    FUJIFILM EF-42 reviews

    EF-42 Flash is rated 4.4 out of 5 by 92.
    Rated 5 out of 5 by from Spot-on power for X-T2 I have very simple flash needs bouncing flash off the ceiling to photograph my dogs. I'd used the 580EX when I had my Canon 1DX Mark II but recently bought the Fujifilm X-T2 and did not need the overkill of their top range flash. However I doubted this medium power flash could do the job. I am happily surprised! The flash is excellent does exactly what I need it to do. Added the diffusion dome as an extra, but have not needed it. Flash is very simple to use, and exposure is TTL varying with exposure compensation. The size is a factor here the unit is not too big. Highly recommend it for the smaller-scale X-T2 or other Fuji camera. Getting beautiful all over lighting and spot-on exposures.

    Rated 4 out of 5 by from Monster claw This came with the special issue X100 but does not necessarily mate well with it. As the X100 has excellent low light performance and low noise levels the need is little for such a powerful torch. However the unit is very powerful and has an enormous reach. I have not used it much but find it difficult to get the low level fill I wish for. It is light but it is bigger than the camera itself which defeats the purpose of the X100 and main attraction. In the context of X100 it is an overkill but I know the attraction of having that kind of power for photojournalism and possibly landscape photography and will pursue that line of thinking in the future.

    Rated 5 out of 5 by from MISSING LINK ????? I purchased the HS 30 fugi camera about 3 months ago and have benn very pleased with the results. However, after noticing the limited capability of the on board flash it was time to upgrade to the EF 42 shoe mount. It truely is the missing link to this camera, it allows me to take so much better flash pictures. I went to a wedding recently and was able to capture large groups with no trouble. It also allows me to bounce the flash and be more creative, sometimes direct flash is too harsh. The EF 42 flash is lightweight and uses easily accessible AA batteries and gives a good amount of flashes per set. Do yourself a favor and get one, you won't be sorry and your pictures will be the talk of the town. Fugi always a great product.

    Rated 4 out of 5 by from Decent choice for X Series cameras I just received my Fuji EF-42 flash unit, and I have some random thoughts to share, in case anyone else is interested in it. First, some background: I have a lot of flash units, ranging from a dozen or so speedlights to various monolights to big studio pack and head systems. At work I tend to light a lot of different assignments, so working with on- and off-camera flash is something I do pretty much every day. When I got the Fuji X system, I decided that the high-ISO capabilities were so good that I would not buy a flash to go with it. No need. And anyway I can always stick a Canon speedlight up there and use it on manual, right? Yeah, ok, so I've shot a couple of things recently where I could really have used a flash, and a TTL flash is just so much easier to use on-camera. So I ordered this one. The EF-42 is about the same size as a Canon 430 EX II. It takes 4 AA batteries and has a guide number in the same range as any other 4-AA speedlight. Not wildly powerful, but not bad. The control interface is very simple -- an on/off switch, a charge lamp/test button, and two control buttons: Mode, and Select. The head is fully articulated and can be turned it almost any direction; there is no interlock on this movement. Output can be varied with Exposure Compensation, 1.5 stops in either direction. Manual control is possible, too, from full to 1/64 power in full stops. The control interface is kludgy -- scroll through every setting using the MODE button until you reach the setting you want to change, then use the SEL button to change that setting, then wait several seconds for the unit to reset. With fully charged NiMH batteries, recycle times were about twice as long as a Canon 430 II flash unit. Performance: OK, this is what counts, right? TTL exposures seem very good, especially for bounced flash. The camera gives me perfect fill-flash from the EF42, and maintained the perfect overall exposure and color balance. Surprisingly, I can use this with my usual full-auto settings on my X Pro 1 and XE-1 cameras, including auto-ISO and auto white balance, and the camera and flash work very well together on the final exposure. Overall impressions: Not bad. Construction and user interface aren't the same as the Canon speedlights. The size is just about right for an X Pro 1 -- it's large, but not overwhelming. It might be too large on an X100S, though. If one needs a fully capable TTL flash for the X series, this is probably the best choice.

    Rated 5 out of 5 by from Necessary Addition I purchased the EF42 to compliment my Fugi HS30. This is definitely the missing link. I have a dslr but it's a pain in the neck literally to carry all that equipment around all day long especially in the amusement parks of florida. The flash lets you take some great pictures once the sun goes down. It has enough power to really get out there and runs on AA batteries. You really do need this to complete the outfit. It takes great group shots when you just don't have enough flash on the camera. A must for those family weddings. The price is really reasonable too. Fugi does make a nice product for those times when you just don't feel like dragging all your stuff around. Keep up the good work.

    Rated 4 out of 5 by from Good Unit This flash does what it's supposed to. Only reason for 4 stars is because of the slight lack of sensitivity when it comes to the automatic / digital mode. Seems to me that the camera (X-T1) should communicate the slight differences and give a better lit final product. I seem to get more pictures that look like I used either a point & shoot or a cheaper flash. I've used both Nikon and Canon for my 35 year photographer career so I know what it is I'm talking about and what I see as lacking. HOWEVER - using this in manual mode (for me) works GREAT! Can pretty much illuminate a :ARGE area with no problems at all/

    Rated 2 out of 5 by from Really rudimentary flash I am eagerly awaiting the new EF-X500 so I bought this to tide me over. Unfortunately, I tried the Nissin i40 but it isn't compatible with the newly released X-T2. Many reviews talk about build quality and I really don't see a problem with it. It is on par with some of the older Canon flashes I used to use like the 430EX or 550EX. The size of the EF-42 is about equal to a Canon 430 or Nikon 700 series flash. The main problem I have with this flash is the very rudimentary (or lack of) controls. There are essentially two buttons, one for mode and one for settings. If you use any flash exposure comp or manual power, you need to toggle through the power levels. It's sorely missing an up and down toggle. For example, if you find yourself at 1/2 power and need to get 1/1 power, you need to cycle through 1/4, 1/8, 1/16, 1/32, 1/64 before returning to 1/1. On the flip side there aren't any intermediate power levels between full stops and the lowest setting is 1/64, so there aren't too many power levels to cycle through. The second major (for professional use) problem I have is that recycle is very poor. I sort of knew this going in, but there aren't any other options for a top-level Fuji flash with TTL at this point in time for the X-T2. There is no option for battery pack so you are left with perhaps one of the slowest recycle times in a flash. Also, do not expect the red AF assist light to work on your Fuji camera and the shoe does not lock securely into your cameras' hot shoe. You have to tighten the wheel and it just holds the flash by friction. I really like the Nissin i40's locking shoe better. Overall, it's a pretty bad flash but one of your only options for the Fuji system at this time for a full swivel TTL flash. Fortunately, the flash is fairly cheap and once the new EF-X500 hits the market, I'll just sell this off and not lose too much money.

    Rated 4 out of 5 by from Great for the price Let me start by saying that I'm normally a Canon shooter and am used to their high quality speed lights. I got this light to complement my new Fuji x-t1 walk around camera. Its a great, no bells, no whistles flash. It has TTL but not a lot more. It's controls are very basic but also easy to use. The housing feels a little flimsy compared to a Canon or Nikon but at 1/2 - 1/3 of the price it is good enough for me. It'll take some knocks into the wall but don't drop it. If you have a fuji or just want an extra manual flash for use with RF triggers, this is a great choice.
