Sigma EM-140 DG Overview

  • 1Description

The Sigma EM-140 DG Ring Flash for Nikon AF cameras is ideal for photographing subjects in fine detail - close-up photography - and is extremely effective for scientific and medical applications.

Dual flash tubes can fire simultaneously or separately. Using only one flashtube creates modeling, which can give a three-dimensional feeling to the subject. The Modeling Flash function makes it possible to check for reflections and shadows before actually taking the flash picture.

A wireless flash function is also available, where the EM-140 DG is used as master and the EF-500 DG Super as a slave unit for creating fine shadow details. High Speed Synchro functions are also available for advanced flash photography.

55mm and 62mm adapter rings are included with the flash; 52mm, 67mm, 72mm and 77mm adapters are sold separately.

Fully dedicated with i-TTL/D-TTL with Nikon photo or Digital cameras
Wireless TTL flash control (4 channels)
High Speed Synchro flash
Stroboscopic effect (power level and frequency customizable)
Modeling light, also provides AF assist

    Sigma EM-140 DG Reviews

    EM-140 DG Macro Ring Flash for Nikon AF is rated 4.6 out of 5 by 66.
    Rated 5 out of 5 by from Easy to Use and Works Great! I purchased this flash so that I could get a much better depth of field in my macro work for subjects that are not entirely still such as plantlife, insects, etc. by shooting in the range of f/22 to f/32 with my Nikkor 105mm f/2.8 macro lens. The user manual for the product is pretty dated but it was somewhat helpful in getting acquainted to the flash's various settings and functions. On my first use in TTL mode, I got a bunch of images that are ready for production. I had no problem at all getting great images from using this flash the very first time out in the field. I am very happy with it and highly recommend it to anyone doing serious macro work.

    Rated 5 out of 5 by from Great product- I would buy it again I am using this product with Nikon D90 and D7000 with 100mm macro lens and a 18- 105 zoom lens. This product is nearly perfect. Easy to understand and to use. Instruction book is easy to understand and apply. I am happy I bought it from B+H . Great after sales and service. My only reservations are that the module needs to be pushed all the way to the end of the camera hotshoe to work properly. It took me about an hour to figure this out. I don't think it is a problem with either the Nikon or the Sigma unit itself. But, be aware that with the configuration I noted above, the camera, the lens and the flash at the end of the lens makes this setup HEAVY. So, it is best that you use a fast shutter if you intend to use indoors. I guess you would have to also crank the ISO as well. All in all, a great purchase. Well worth the money.

    Rated 4 out of 5 by from Good for hiking and field photography. Used for close-ups of flowers mostly and other subjects of interest. More compact and easier to carry and set-up than the Nikon R1C1 system. Works satisfactorily in the TTL and manual modes. Instructions are not complete. Does not explain the flash operation when using AIS lenses (I use the Nikon D2x and the D300 which can be used with AIS lenses and use manual focus to better control the focus plane.) Not as flexible as the R1C1 system in controlling off camera flashes.

    Rated 3 out of 5 by from Great Except for Dead Flash Tube I bought my unit in March of this year and it worked beautifully until last week, when the left flash tube kicked the bucket. I'm contacting Sigma as we speak, since the product is still under warranty. Its a shame because the unit worked beautifully for extreme macro photography. However I've been using it with the right flash tube only, and its been okay. As a side note, this unit is a little hard to figure out at first, and the manual provided is less than useless. Its definitely a learn-as-you-go product. Whether it was really worth it or no will depend on the repair quote Sigma gives me.

    Rated 5 out of 5 by from Pleased with the results I bought this flash to use for Micro photography and more specifically with my 105mm Micro lens. So far Ive had excellent results. Im surprised how well the exposures have turned out. Im having far better success than when I used an off camera cable and flash. Its much easier to use and the results are even better.

    Rated 4 out of 5 by from EM-140 DG Macro Ring Flash or an off camera speed light. I purchased this ring flash four years ago and it works well and has many useful features. Using any kind of flash for macro work increases your options considerably. You can use low ISO settings and small apertures for more DOF. About a year after I bought it, I decided to purchase a Nikon SB700 speed light for a general purpose flash. A short time later I started using it for my macro work as a remotely controlled off camera flash. Once you get the flash off the camera, the results are so much better and more natural, especially if you use a small soft box. You can easily move the off camera speed light left, right, over, under and behind the subject and you get more natural light and shadows. The ring flash works well, but you end up with a very flat, low contrast light that is very unnatural looking for insect and flower macro work. The EM-140 is a nice product and it's well made, but I just wanted to post this review for anyone who is debating on whether they want a ring flash or a speed light. My SB700 didn't cost that much more than the ring flash, but I can use it for so many more applications. The other thing about the ring flash is that you have that big ring flash hanging right off the end of your lens, which is awkward and more intimidating to any wildlife you are trying to get close to. You also have to have adaptors for the lenses you intend to use. If you really need a ring flash, then I think the Sigma is great for the money, but even if you use the left or right bulb to try to add more contrast, you will never get the results that you can get with the off camera flash when shooting natural subjects. I wish I could have come across a post like this, before I bought the ring flash, because I haven't used it since I bought the speed light three years ago. If you have a camera that doesn't have a built in flash commander, then you may have to purchase a separate flash commander device to use a speed light off camera. Anyway, these are just a few things to consider, before you buy.

    Rated 4 out of 5 by from Works well for intra-oral photos Use the product with a 105 mm Nikkor Macro lens and D3000 body for dental photography

    Rated 5 out of 5 by from Works like a charm or maybe a ring flash I'm giving the Sigma EM-140 DG Macro Ring Flash five stars because in all my testing of this flash everything seems to be very good. I haven't had it long and only used it for testing indoors and out and it preforms very well. How long it will last...I don't know but it seems to be made well and attaches to all my lenses securely. Instructions could be better but if you have any experience with the better flash units you shouldn't have a problem figuring this one out. Comes in its own travel case, (way too large to fit in any of my travel Pelican cases) but it is nice. You will most likely need adapter rings for your lenses since the unit only comes with two. Over all I think this was a good buy.
