    Nissin i40 reviews

    i40 Compact Flash for Four Thirds Cameras is rated 4.1 out of 5 by 16.
    Rated 5 out of 5 by from Great little flash for Micro 4/3 Everything you have read about this flash is correct. It is smaller than anything I have found with similar output. Manual dials are easy to use. Fully articulated head with built-in bounce card and included cap-style diffuser provide great flexibility. I have used this flash on and off camera, in slave mode, Olympus RC TTL mode with my E-M10's built-in flash as commander, and in manual with a Yongnuo RF-603 N2 trigger. This little Nissin has worked well in each situation. Of special note is the bounce card: it is a plastic-backed slab, not a mere flexible card like competitors. I love that it is designed so that it can be raised or lowered inside the cap diffuser. Very nice touch to reduce light loss to the back, but still get benefits in other directions. I tried the more expensive alternative from the big camera manufacturer and was disappointed. The Nissin i40 is a keeper.

    Rated 5 out of 5 by from Better than the Olympus I've had this and the FL-600R and I can tell you this is leaps and bounds better. It's smaller, well built, easier to use(manual dial controls you can actually feel), the video light is brighter and adjustable. And the light is consistent. The olympus video light was always twitching. Also the pop-up bounce card is useful and not tiny, and a diffuser is included! I do wish you could use the light and fire the flash, that's not a dealbreaker.

    Rated 4 out of 5 by from Adequate I use this for interiors/real estate photography. I had the same flash for Sony before I moved to Panasonic and it seemed better to me than this one. Could be a difference in the camera technology & not the flash...? For most rooms this is an adequate medium quality flash. A little over-priced but it's a great size for mirrorless systems. It is very easy to adjust the head angle, rotate front to back, swivel, etc. No locking buttons to push when you want to make a directional adjustment, which to me is a PLUS. I HATE having to hold a button down just to select a different angle, etc. Switching from mode to mode (Auto, TTL, Manual) is very easy & adjusting the output couldn't be simpler. Comes with a snap-on diffuser which is nice.

    Rated 3 out of 5 by from Good ideas, quirky execution The i40 is based on two good ideas: keep it small, so it balances well on Micro Four Thirds cameras; and use simple control knobs instead of a complicated LCD panel.The execution of those ideas is a bit quirky, though, so I'd suggest making sure you can live with the i40's peculiarities before committing to it.What I like about it:-- It's fairly compact -- although not that much smaller than my Olympus FL-36R flash -- yet has a full range of features.-- Balances well on my Olympus E-M 5 camera, and works with all its TTL features including the RC wireless flash system.-- You can tilt and swivel the head without having to push any lock buttons.What I don't like:-- The control knobs aren't really such a good idea. They're hard to read in dim light (which is exactly where you're likely to need a flash) and they don't stay put. I've had pictures spoiled because I brushed against the exposure-compensation knob and changed its adjustment without realizing it.-- The controls for manually zooming the head and engaging high-speed flash sync are poorly labeled and hard to use.-- The head tilting mechanism is hinged at the back edge rather than at the center. This makes the i40 hard to fit into some flash brackets and modifiers.-- While it works as a slave flash under Olympus' RC wireless system, it can't be used as a master flash. This feature (or non-feature) is poorly documented in the instructions, so beware.-- The case is a peculiar cube-shaped design that takes up a lot of space in a camera bag.-- The battery door is hard to close because you have to press it in against spring tension while sliding it.Given that it's not THAT much less expensive than the similarly-featured Olympus FL-600, it's hard to see much reason to buy the i40 unless compact size and good balance on the camera are especially important to you. I thought seriously about sending mine back, but decided to keep it because it handles well on the E-M5.

    Rated 5 out of 5 by from Brilliant compact but powerful flash Very simple controls make it the best flash I have ever used by far. I had owned FL-600r at one point but could never get along with it. It was a little too big snd heavy for E-M10 and controls were pain. i40 balances perfectly on an m43 body and has all the important features which are easy to access. Great for outdoors and indoors. The only con is that the flash doesn't fold up nicely for storage.

    Rated 5 out of 5 by from Ease of Use and Power in a Small Package To preface, I'm no professional photographer. I've had my eye on the i40 for M4/3 - anticipating its arrival when I saw it released for other platforms. Mine was purchased for use with my OMD-EM5. The Olympus equipment seemed either too large (physically) or under powered and under-featured for my needs. What especially attracted me to the i40 was the dial/analog controls. The i40 is not only easy to control, but is sized well to the OMD lineup of Olympus cameras. In fact, for those who are super-critical, the coloring on the i40 matches the EM5 to a tee, right down the light blue lettering...uncanny. In terms of performance, indeed the i40 is a performer - putting out a very respectable amout of light with a very adequate recharge rate. Initial power-up could be quicker, but this is a minor nuisance only. I don't think anyone, amateur or pro alike, could fault the build quality of the i40. This was the first thing I noticed - right down to the spring loaded battery access door and diffuser, owning the i40 has proven very satisfying.

    Rated 5 out of 5 by from Perfect for Micro Four Thirds This is perfect for my Olympus OM-D. Great light, smooth coverage and fills the area evenly. Came with a diffuser that works really well. Bounces in any direction. Works well as an off-camera slave flash triggered by the clip on flash that came with my E-M5. So small. So light weight. Well balanced on my camera. Controls are super easy to use.

    Rated 1 out of 5 by from One glaring flaw I researched this product quite a bit before purchasing it. The size was just right for my Olympus E-M10, the controls were effective and straight forward. However, after receiving it, I tried using it in fully automatic mode with my Olympus 17mm f1.8. The flash coverage was horrible leaving deep vignetting in the corners especially the lower left and right corners. Maybe this was defective? I don't know but the flash zoom appeared to be operating. Anyway, the unit was sent back and replaced with two Yongnuo 560 III's plus a Yongnuo 560 TX. This works great. I still like the idea of having a dedicated flash that supports the M43 flash system. Maybe I'll try it again in the future.
