Great powerful compact flash.

Perfect for my Panasonic G9 and GX7. My OLY M43 flash was ok but broke 2 twice. This flash is almost as powerful and I like the simple quick dials.

After much research I bought the two unit i40 kit.  Works great with my Olympus Pen-F.  The i40 is compact but packs a powerful punch.  They are well-built and should take the normal jostling around your camera bag--emerging unscathed and ready to go to work.  It did take some time fiddling with the i40 and Pen-F settings to get things coordinated.  The i40s included directions and the downloaded version left a lot to be desired.  Still Ill give the i40 five stars.

Excellent flash

After 2 years of owning this flash I can say it has been an excellent investment. Its extremely well built, compact, and thoughtfully put together. I should mention that near the 2 years mark of ownership it did develop a slight issue where it would not fire when aimed straight up. But Nissin, in a no-nonsense, no-question-asked manner (and with the help of B&Hs excellent invoice history) replaced it. Truly remarkable service.

Very good and fit my camera.

I really like this smallish but effective flash. It's the right size for my Sony a6400. I also like that it is simple and straight to use. My other flashes have many more disks and lights to deal with. This flash does the job, is easy to use, small and light to carry or pack. Glad I have it; I can see myself using this flash whereas the others stay in the drawer!

Good thing in a small package

It just works! Small, surprisingly heavy, and feature packed. The only downside is the need for four (4) AA batteries.

NIssin i40 on a Fuji X100F

By Gerald
Rated 4 out of 5

I specifically purchased this flash for the small body on the Fuji X100F and think the size is a good match. TTL & Auto Modes: Both modes initiate TTL exposure when the flash is hot shoe mounted, or off camera with a TTL cord (Use Canon pinout cords for Fuji bodies).  The mode difference being that in the Auto mode, TTL power compensation (FEC) must be done from the camera's TTL menu (+-   5 stops in 1/3 stop increments in the X100F)  The TTL FEC dial does not change power in the Auto mode. In the TTL mode, you can make TTL FEC changes using the dial on the flash head (+- 2 stops in 1/2 stop increments). This is a really nice feature, in that you can adjust the FEC without looking, using the audible clicks on the flash dial for feedback, rather than looking at the dial on the flash head or looking at the cameras TTL menu.  In Manual mode, you change flash power on the flash head, from full power to 1/256th power. The camera menu Manual power setting will follow. If you try to adjust the flash power in manual from the camera menu, the power setting will return to whatever the manual setting on the flash head is. Zooming: The flash head zooms from 24 mm to 105mm, plus has an Auto Zoom mode. This is changed by holding down the power button for three seconds while in the Manual mode. It does not appear that you can zoom the head in TTL or Auto exposure modes.  Verified that with version 18-9 firmware that HSS is active. Shot fine with the Fuji at 1/4000th How to check Firmware version of i40: Turn on the flash, pressing Pilot button and Power button at same time for a second. The indicator lamp A and C will pulse until you take out batteries, the pulse count identifies the firmware version. For example:  Indicator lamp A twinkling 18 times, Indicator lamp C twinkling 9 times, i40 version is 18-9, which is the latest version for Fuji. I also use the Demb Flip-It with Diffuser and find the Photojournalist model is a good fit.

Does it have Automatic aperture modes so it will work on a Leica m6? I know it has a manual mode, but often nikon flashes have a good aperture mode to control the flash when working with leicas.Thanks
Asked by: Anonymous
The Nissin i40 has an auto mode. If you set the Leica to manual exposure this flash will sync with your camera and adjust the output based on your distance to the subject.

question

For use with Nikon remote CLS, it looks as though there are settings to choose between Group A, B and C. Is this correct? Is there also a Channel setting available? Also, is there a PC socket? Also, is there a shoe locking pin as on Nikon brand speed lights? Thanks.

Are these units, the i40 and i400 for Nikon, pre-updated to firmware version 18-11 so they are compatible with z6/z7/z50 Out of the box? (I don't want to send in an unit to nissin just to get it updated)
Asked by: Cristian
Hello Cristian, That is a good question, and a difficult one to answer. We (ExpoImaging) have been the Nissin distributor in the U.S. since June 2019, and we update the firmware of every flash we ship to our customers, including B&H. You cannot identify which version of the firmware is installed on a flash without powering up the flash, but if B&H purchased the flash from ExpoImaging then you could identify the firmware with the flash's purchase date (from ExpoImaging) and serial number. Nissin i400. Nissin released firmware version 2.0 (0102) for the i400 on July 10, 2019. This update added compatibility for the Nikon Z6/Z7. Any i400 purchased prior to July 10, 2019 would need its firmware updated to be compatible with the Z6/Z7. Nissin i40. Nissin released firmware version 18.11 for the i40 on Dec 19, 2018. This update added compatibility for the Nikon Z6/Z7. Any i400 purchased from the distributor prior to Dec 19, 2018 would need its firmware updated to be compatible with the Z6/Z7. If you have any other questions please contact us directly by sending your email to [email protected] Our offices are open Mon-Fri from 8:30am to 5:00pm PST. Best Regards,
