    Adds great production flexibility

    This product is for:

    1. Anyone who is tired of repeatedly moving CF cards (or the camera) from the shooting location to a computer, in order to transfer images.

    2. Anyone who needs to seamlessly transmit pictures from a shooting location (where there is WiFi or wired Internet service) to an FTP server anywhere in the world.

    Nikon has provided a lot of flexibility and capability (subject to the limitations below):

    1. If you don't have an FTP server, you can use a personal computer (in which case the computer must be on the local network -- no across the world transfers).

    2. You can have all pictures taken transferred, or just the ones the photographer selects. In "thumbnail transfer" mode, a person at the computer can select which full images need to be transferred.

    3. The WT-4 grabs images immediately from the camera's memory and saves them in the WT-4 (1GB limit); it then transfers them as required, so that the photographer can change CF cards when full and continue to shoot w/o worrying about the transfer (subject to the 1GB limit).

    I love it, but users need to be aware of the limitations:

    1. Setup (inherent in using WiFi): I'm computer networking-knowledgeable, so setup was trivial for me, but you will have some learning to do if you've never used WiFi before. I understand that Nikon customer support has been very good in this area. Hint: set it up using a wired Ethernet connection first.

    2. WiFi network transfer speed (inherent in using WiFi): Don't expect the transfer speeds you see with a wired connection. I see a full D700 NEF transfer in about ten seconds (this with a 802.11g WiFi network).

    3. Cabling: Nikon started by having the WT-series in a camera grip for various camera bodies, but probably due to limited sales, decided on one separate unit that can be used with multiple bodies. Unfortunately, this decision requires a connection between the camera and the WT-4. The WT-4 is very lightweight and can be on a belt or pocket, but there is that 4ft USB cable from the WT-4 to the camera that can get in the way. Ideally, the camera should communicate with the WT-4 wirelessly (Bluetooth?), but that would require an additional drain on the camera's battery. So, I think the WT-4 makes the best of the present camera situation.

    Note: the WT-4 includes a nice, snug dust cover for both ends of the USB cable, when plugged into the D3 or D300. More recent packaging may include covers for other camera bodies, but mine did not include a dust cover for the D700. A message to Nikon customer support, and one for the D700 was on the way.

    I use the WT-4a with my D300 to transmit NEF files back to my MacBook as I shoot studio sessions and theater performances. This has two benefits:

    -- I get a continuous backup: every shot is saved both on the camera's memory card and on the MacBook's hard disk.

    -- The pictures are ready to review with the director as soon as the session is over; I don't need to spend extra time transferring files from the memory card to the laptop.

    These are big pluses in the type of work I do, and the WT-4a in general does a reliable job. It's a bit tricky to set up (especially since the included setup software isn't compatible with MacOS X "Leopard," the system software I use) but you only have to do the configuration once, and after that the unit is very easy to use -- just turn it on and check the status displays occasionally to make sure it's transmitting.

    As with any WiFi device, range is extremely variable depending on distance, environment, interference, etc. Generally I can roam anywhere in a studio without losing the connection, but sometimes get dropouts in a large theater hundreds of feet from the laptop. This doesn't result in losing any shots -- the WT-4a keeps track of the ones that haven't transmitted and "catches up" once it's back in range -- but it does sometimes allow a backlog to build up that takes several minutes to transmit.

    Things that aren't so great, aside from the complicated one-time setup:

    -- It's convenient that the unit uses the same battery as the D300, but battery consumption seems fairly heavy. I usually run down the battery in the WT-4a long before I run down the one in the camera.

    -- It gets noticeably warm in operation. It's actually kind of nice to have a toasty WT-4a in your pocket in chilly weather, but on a summmer day it might be a bit uncomfortable.

    -- The case that comes with it is rather chintzy considering the price of the unit. I know Nikon sells another case, but haven't seen it so don't know if it's any better.

    Summary: probably not many people need to do what this unit does -- but if you do, and if you don't mind jumping through some hoops to set it up, it will work well for you.

    (And if you've read this and are thinking, "Why not buy one of those slick EyeFi cards instead?", well -- the EyeFi transmits JPEG only, not NEF, and once it's filled up, you have to put in another EyeFi card to keep shooting. The WT-4a transmits raw files, has longer range, and lets you keep shooting with multiple cards.)

    Comments about Nikon WT-4a Wireless Transmitter:

    I like the ability to control live view directly from my computer... However the product definitely has limitations. To connect the transmitter to the network one must FIRST setup a settings download on your computer and plug the WT4A into it so it's not a very fast process. This is a great tool for studio work but I don't see myself using it much in the field.

      Comments about Nikon WT-4a Wireless Transmitter:

      I use the wt4 in party and social scenes but not for much longer too unreliable. It sends photos to the memory card on my d300 and sends other files to the computer, I guess depending on whether the camera can communicate properly with the wireless system. I use a competitor product that is far superior to this and no cables to connect to the wireless device. I would recommend this wireless system for studio style shooting only as too unreliable when walking around in a room. I even reoriented the router and still the same problems

      I'm a working pro and thought I had a pretty good handle on digital. It took me two whole days to get this thing set up and I'm still not confident I have it right. So far can only use the thunbnail view and don't have the ftp set up yet. Also, in order to control the camera from computer you need to buy additional software. Also, this system won't work with Mac Lion OS so my new computer is useless. Nikon needs to simplify the set up and interface and update Mac software. Cool toy but not worth the [$] yet.

      Comments about Nikon WT-4a Wireless Transmitter:

      The WT-4 works as advertised, no doubt about it. They're however are a few cons. First, the setup utility does not work on the latest Mac OS, Lion, big set back to say the least. Nikon as released a statement that they are working on it.
      Secondly, The USB cable coming out of the USB port on the WT-4 has a tendency to easily pull out during the process of moving and relocating during a shoot. Not a deal stopper but an inconvenience. Also, the on off switch is covered over by the strap when in the carrying case.
      A great App for the WT-4 is "ShutterSnithch" found on the App Store if you are an iPad and/or iMac user.
      The Wt-4 is a great tool, just needs a little work.

      Easy to set up. Just follow the directions. I also have the WT-3 which I prefer because it is has the profile of the battery grip. Range is not impressive compared to the the WT-3 with the external antenna. For [$] the unit feels very cheap and should have included a battery. Hopefully it will be compatible with future camera models and not become obsolete as did the WT-3 (will only work with the d200)

        Comments about Nikon WT-4a Wireless Transmitter:

        I use this transmitter in ad-hoc mode, which is a direct connection to my MacBook Pro on the sidelines, in hotel ballrooms, and other large venues where a wi-fi connection isn't available.

        The feature that truly helps is the buffer. Rarely mentioned in reviews is the fact that if you wander out beyond the range of the transmitter's signal, the image or images that have not been transmitted will remain in the buffer and be sent as soon as you return within range of the network. This is a unique feature most wireless cards do not offer. Knowing that all the images WILL be transmitted is one LESS thing to worry about during a shoot.

        Having the ability to connect directly to a laptop allows my client and their editor to start working on images while we're still shooting. Networked imaging - it's here and with this transmitter is fairly easy to achieve.

              Comments about Nikon WT-4a Wireless Transmitter:

              The speed of transmission of the WT-4a I have recently purchased has left me wanting. Currently I cannot process through more than 7 photos a minute with a D700 set to JPEG Fine Large. At 54 mbs the process through put should be a little more than one 6 meg photo per second. The WT-4a buffer fills almost immediately and doesn't allow me to continue to shoot, locking up the D700 from shooting. The unit gets very hot in use and the battery life time is also very low. The quality of the connection was good and the Camera Control Pro 2 software did a good job.
              For fewer photos per second this could be a very good product, but not for the application I had in mind.

                  I made the mistake of not reading the reviews regarding this item's use with a MAC before I purchased it. I run OSX 10.6.4, and the setup utility does not support anything past 10.5.8. There is no mention of this on the Nikon site. So, until Nikon issues a software update, or I decide to run an older version of my operating system, I have a[$]paperweight.

                  I used this device for about a year with great results.
                  my only concern at the present time is that Nikon hasn't bother to upgrade the set up utility for OS 10.6 (SL) onwards for more than a year, therefore you can't use the transmitter anymore with a MAC computer. At the moment I use my wife's old MacBook running Tiger OS, I use it on location and studio where cables are a hassle. The images are transferred painlessly to the computer where everyone can see them and you don't have anybody "breathing on your neck" at all times.
                  The best configuration I've found is to set up the WT-4 to the AD-HOCK wireless configuration rather than a WIFI so you won't need a router, just the Transmitter and your "old" portable computer.

                  It's a bit of a pain to set up, you MUST update firmware in your camera and WT-4 and download and install the latest Nikon software.

                  Once everything is set up, it works like a charm, sending images to the computer in about 20-seconds after they are captured. Huge image buffer ensures that all photos get to computer even if photographer leaves wireless range for a few minutes.

                  I added a 7db-gain antenna to my wireless router and put the antenna on top of a 12-ft lightstand for much better range between the router and WT-4.

                  Comments about Nikon WT-4a Wireless Transmitter:

                  This product is for:

                  1. Anyone who is tired of repeatedly moving CF cards (or the camera) from the shooting location to a computer, in order to transfer images.

                  2. Anyone who needs to seamlessly transmit pictures from a shooting location (where there is WiFi or wired Internet service) to an FTP server anywhere in the world.

                  Nikon has provided a lot of flexibility and capability (subject to the limitations below):

                  1. If you don't have an FTP server, you can use a personal computer (in which case the computer must be on the local network -- no across the world transfers).

                  2. You can have all pictures taken transferred, or just the ones the photographer selects. In "thumbnail transfer" mode, a person at the computer can select which full images need to be transferred.

                  3. The WT-4 grabs images immediately from the camera's memory and saves them in the WT-4 (1GB limit); it then transfers them as required, so that the photographer can change CF cards when full and continue to shoot w/o worrying about the transfer (subject to the 1GB limit).

                  I love it, but users need to be aware of the limitations:

                  1. Setup (inherent in using WiFi): I'm computer networking-knowledgeable, so setup was trivial for me, but you will have some learning to do if you've never used WiFi before. I understand that Nikon customer support has been very good in this area. Hint: set it up using a wired Ethernet connection first.

                  2. WiFi network transfer speed (inherent in using WiFi): Don't expect the transfer speeds you see with a wired connection. I see a full D700 NEF transfer in about ten seconds (this with a 802.11g WiFi network).

                  3. Cabling: Nikon started by having the WT-series in a camera grip for various camera bodies, but probably due to limited sales, decided on one separate unit that can be used with multiple bodies. Unfortunately, this decision requires a connection between the camera and the WT-4. The WT-4 is very lightweight and can be on a belt or pocket, but there is that 4ft USB cable from the WT-4 to the camera that can get in the way. Ideally, the camera should communicate with the WT-4 wirelessly (Bluetooth?), but that would require an additional drain on the camera's battery. So, I think the WT-4 makes the best of the present camera situation.

                  Note: the WT-4 includes a nice, snug dust cover for both ends of the USB cable, when plugged into the D3 or D300. More recent packaging may include covers for other camera bodies, but mine did not include a dust cover for the D700. A message to Nikon customer support, and one for the D700 was on the way.

                    Being able to go cordless has been great. The only down side is that the battery only lasts up to about 3 hours.

                    Takes a bit of setting up but once that's done it's indispensable. As capture devices, computers, i-phones (i-pads) get smaller this must be the way ahead for the workflow of anyone who does any kind of event, wedding or photography where time is of the essence. Don't know how I managed without.

                    Comments about Nikon WT-4a Wireless Transmitter:

                    I use this with a D3 and a Mac Book Pro. It took several months for Nikon to get the software right for Mac, so that was painful but hopefully no longer relevant. The device works, but the transmission speed on anything but low res jpegs is painfully slow. Within my studio, it can take 30-45 seconds to transfer a RAW image. This is ok for product photography, but I use the D3 for higher volume needs. One of the more interesting bits of software is the thumbnail selector that allows a central computer to monitor up to 5 cameras. Problem there is that the thumbnails are too small even in the "large" size. You cannot see anything well enough to judge by. Camera Control Pro has neat features with the WT4a as well in that live view and remote operation are possible.Still, these are [$] add on software packages, so as a stand alone bit of hardware, the WT4a doesn't justify the [$] price

                      Comments about Nikon WT-4a Wireless Transmitter:

                      I had just purchased a new Nikon D300 camera. I needed a remote option to shoot still photos from a 30' crane. I purchased the WT-4a and Camera Control Pro 2 software. Only took me a couple of hours to test the equipment and off to the job next day.
                      I generated a wireless network from my computer, turned on the transmitter and software and had a connection.
                      I shot jpg images and downloaded to my laptop within 3-4 seconds, would then change framing as needed with the crane and shoot again until I had the image. Then switched to RAW images and bracketed the photos to allow for later creation of an HDRI image. Download of 25mb RAW files took about 25 seconds.
                      Battery life in transmitter and camera was good, shot 400-600 images in each crane setup. When moving crane to next setup, installed fresh batteries and re-charged the previous two.
                      The software and wireless setup worked perfectly.

                      Tricky to set up, but does the job

                          Comments about Nikon WT-4a Wireless Transmitter:

                          I use the WT-4a with my D300 to transmit NEF files back to my MacBook as I shoot studio sessions and theater performances. This has two benefits:

                          -- I get a continuous backup: every shot is saved both on the camera's memory card and on the MacBook's hard disk.

                          -- The pictures are ready to review with the director as soon as the session is over; I don't need to spend extra time transferring files from the memory card to the laptop.

                          These are big pluses in the type of work I do, and the WT-4a in general does a reliable job. It's a bit tricky to set up (especially since the included setup software isn't compatible with MacOS X "Leopard," the system software I use) but you only have to do the configuration once, and after that the unit is very easy to use -- just turn it on and check the status displays occasionally to make sure it's transmitting.

                          As with any WiFi device, range is extremely variable depending on distance, environment, interference, etc. Generally I can roam anywhere in a studio without losing the connection, but sometimes get dropouts in a large theater hundreds of feet from the laptop. This doesn't result in losing any shots -- the WT-4a keeps track of the ones that haven't transmitted and "catches up" once it's back in range -- but it does sometimes allow a backlog to build up that takes several minutes to transmit.

                          Things that aren't so great, aside from the complicated one-time setup:

                          -- It's convenient that the unit uses the same battery as the D300, but battery consumption seems fairly heavy. I usually run down the battery in the WT-4a long before I run down the one in the camera.

                          -- It gets noticeably warm in operation. It's actually kind of nice to have a toasty WT-4a in your pocket in chilly weather, but on a summmer day it might be a bit uncomfortable.

                          -- The case that comes with it is rather chintzy considering the price of the unit. I know Nikon sells another case, but haven't seen it so don't know if it's any better.

                          Summary: probably not many people need to do what this unit does -- but if you do, and if you don't mind jumping through some hoops to set it up, it will work well for you.

                          (And if you've read this and are thinking, "Why not buy one of those slick EyeFi cards instead?", well -- the EyeFi transmits JPEG only, not NEF, and once it's filled up, you have to put in another EyeFi card to keep shooting. The WT-4a transmits raw files, has longer range, and lets you keep shooting with multiple cards.)
