NEEWER Upgraded NW645II-C TTL Flash Speedlite, GN58 HSS Flashlight Speedlight Compatible with Canon EOS R6 R5 R3 R M6 850D 800D 760D 750D 650D 600D 7D Mark II 7D 6D Mark II 6D 5D Mark IV/III

My first experience with this flash was taking it out and watching a piece on the side fall out. Sure it was a decorative piece but still, not a good sign. So I've only had Canon OEM flashes so the build of Neewer was underwhelming. Like snap-together plastic assembly with no rubber gasketing. Moving the flash head is easy because there is no "lock" on usual Canon flashes. It just clicks into place, also, anything at 75 degrees or more is impossible unless you tape it into place. Light output is good actually, very bright and I was pleased by the recycle time, pretty typical of the 600 II-EX flash that I have. Also, works wirelessly as a slave, once you figure the menus out. That's the other thing, really no frills panel for the flash and the menu is a little confusing but afdter about 10 minutes I worked it out to get it to be used as a slave by the 600 II-EX master on my camera. All in all a good second or more flash for a good price. I liked the Neewer better than a Godox I had because the Neewer shoes is made of metal and not plastic. A big plus.

Useful as a secondary flash that triggers off other flashes but not so much as a daily-driver. The interface is fairly un-intuitive and is mostly a chore to deal with. If you need a basic flash this can be useful but if you are looking for your first flash I'd recommend something else with more features and a more robust interface.

This is a rather bare bones unit. Zoomable pattern, nice dual diffusion/reflection flags built in, plus a diffusion "scatter cap."However, it does have built-in optical slave modes that can eliminate the need for a radio-attachment. It will optically slave in S1 and S2 modes for manual use in a TTL setup, but with the addition of a "shoe emulator" transceiver, like the Yongnuo YN622C-TX/YN622C-II system, it can operate in full ETTL mode in a three-group flash setup, for far finer control.Still, you trigger everything you need for manual setup without the additional radio support. You'll just need to meter or pop a few frames to lock in your exposure. You'll have all the optical trigger options necessary to make sure it fires.I particularly like the extra pop-out diffuser that you can see in my photos, in the shot with the small pull out bounce card. The diffusion cap is nice--too bad the case is sized too small to put it in with the flash, but hardly a deal breaker.Low cost flashes like these have created a relatively modest point of entry for photographers looking to create multi-light portraits, or to light larger and more complex scenes. What you lose in a unified ecosystem (Canon in my case) I find that you tend to gain with a few accessories (like the Yongnuo trigger/transceiver kits I mentioned). This allows you to buy lights essentially like a commodity, knowing that you can tie them all together with reasonably priced trigger units. Just don't expect one brand's trigger to perform with another brand's flash, without a dedicated transceiver unit.Even when you add all that up, they represent a bargain compared to the "big daddy" brands, and have become just as dependable in the performance department.Five stars for a solid little performer.

All the Neewer NW635-C TTL functions are carried over into this upgraded NW645II-C, so thru-the-lens (TTL), manual, multi-shot, S1, and S2 flash modes are here. The new and upgraded additions in the NW645-C are high speed sync, first curtain, and second curtain flash modes. For the small increase in price, these new features are worthy and useful additions.But I do have a couple of nits to pick. Comparing the instruction manuals, the version for the NW635-C is more complete and detailed. This, I think, would be the better manual for someone just beginning in flash photography. Also, the placement of settings which appear on the new screen has changed, and the type was bolder on the NW635-C. Again, I prefer the NW635-C over the upgraded NW645-C in this respect.Overall, however, Neewer still provides a very good flash for the money. The upgraded features are welcome and they make it easy to recommend the new version.

This is a basic starter flash. It is very light on features, but it will do the trick if you are just getting started or don't want to spend a lot of money. If you are looking to use multiple flashes in your lighting set up, there are probably better options. Worked fine on a Canon R6 and also a 5D Mark IV.

初日のR6での使用はまずまずだったが、翌日にR3,R7で使ってみっところ調光せず、HSSが勝手にコロコロ変わり不安定に。じきに発光しなくなりました。対応と謳っているから試しに買ったのですがやはりだめでしたね。

This is a review of the NEEWER Upgraded NW645II-C TTL Flash Speedlite. It comes in a cardboard box with the flash in its own carry case that also holds the small stand, a separate clip-on defuser (this does not fit in the carry case oddly, but supplied separately in the box) plus a well written instruction manual. The flash has a Guide Number of 58, has a built-in optical slave trigger facility, in place of a radio trigger that does feature a lot these days in other specified models. Also there is a PC socket and mains adaptor socket, both covered by a rubber type cover, to the side and the front - see photos. There is a pull out ‘pop-up’ type defuser plus bounce white flash card. It requires 4 x AA size batteries (not supplied) to power it like most similar looking units of this type of design do. I am using this unit with my Canon 7D and it works flawlessly or just the same as any other type of flash would. I used it at a small retirement presentation party and it delivered very good, well lit and balanced photographs that, something I wasn’t aware of beforehand, are being selected to go into a presentation album of the event, so can’t say fairer than that.

I got this for my canon camera and it has proven to be a useful tool. It is a massive upgrade from the one I had before. Over a period of time, I have gradually built my photography kit to fully include this speedlite. This light has a good amount of throw, along with fast recycling time. The TTL functionality has so far been spot on I have found. It is a bit annoying that they opted for AA batteries as you constantly need to replace or recharge them, but that has certainly kept the cost down for purchasing. The price is quite reasonable.It keeps it on auto and I never had any issues with it. I find sometimes it leaves a strong horizontal vignette on photos but it’s very rarely and usually if I take a couple of shots it corrects itself. This may be due to some tweaking I need to do. The Build quality isn’t too bad, too much plastic for my liking but it seems to be well built and it makes it weigh near to nothing.The interface is very easy to operate and reasonably good that you will pick it up in minutes. For professional event use during high-frequency shooting, I have very specific requirements, exposure consistency, this seems to be its weakness. There is no option to connect an external battery pack which in itself shouldn't be a problem but as the unit gets used the flash recycling time gets slower, and slower and slower.After just 15 mins of inconstant use, the recycling time at 1/4 power dropped from very quick to over 2 seconds, this is a problem for me. Despite this, for a mid-range speedlite and a reasonable price, this is more than good enough for amateurs and upcoming photographers that need something with a good throw rate and a decent recycling time, as long as you have plenty of batteries to hand.All in all, for the price there isn’t much to grumble at. It is easy to use and works quite well.Hope this review helps.

I tested this on a Canon 90D, 7D & 250D firstly on the cameras shoe mount and as you would expect I was able to change the flash settings from the camera and it flashed on all three cameras which is great. I then tried using it as an external camera I do not have a transmitter so was using the camera inbuilt flash to fire the external flash and I got this working on the 90D & 7D but could not get it to work on the 250D. It might work if you have a transmitter instead but I do not know so this is something to keep in mind if you have a 250D and want to use it as an external flash.The build quality of the flash is very good and feels solid will last for a long time if treated correctly like anything else.The controls on the flash are very responsive and it is very else to control and setup I am no flash expert and I had this up and running in a few minutes.This requires four AA batteries which is not that big of a deal if you have rechargeable AA batteries, I would have liked it to have come with a rechargeable battery that would have been a nice touch.Also comes with a diffuser and a mini stand which you can also attach to a tripod/light stand. Overall I am very happy with the Neewer flash speedlite and would recommend it.

Absolutely love this flash. It arrived very well packaged. It comes with 1 x NW645II-C Speedlite, 1 x Mini Stand, 1 x Soft Diffuser, 1 x Protective Case, and 1 x Manual. This flash is Compatible with Canon cameras. I have to say I'm very impressed so far I've found that it's much higher quality and much more useful than I expected. The flash has a fantastic build quality and feels sturdy to hold, the flash head moves smoothly. I tested it and it works great. Easy to use and I was shooting within minutes. TTL and Slave modes are also easily set up.Recommend it.
