[20 to 200 mm] This is very good flash

[1/1 to 1/256] Its is amazing when you can have something at a reasonable price and still get amazing Quality, This was recommend from a friend and now we can recommend this to another friend. Thank you for having the item we need for the wedding.

[-7 to +120°] Best product reasonable price. Friendly website and help to save taxes.

[PC] Easy to use

[1.505 lb] This wireless remote control for Neewer speedlights shares the same capability of pricier systems. Easy to set up and use, it works well with in camera sensor iTTL metering. Much more reliable radio remote control than optical systems such as older Nikon speedlights. It will read zoom lens settings and send the data to all of your slave strobes. Neat to hear all of them remotely respond to your lens! But one caveat. Out of the box my QPRO-N was ignoring in camera compensation settings! I emailed Neewer and they sent me the latest firmware update which wasn't even on their website. Worked like a charm. Thus, they earned a full five stars.

[4x AA] The most consistent clear flash I've ever hsd

[-7 to +120°] One technique in capturing images of hummingbirds is to use a bank of 3 or 4 strobes (flashes) to provide the light source and capture or stop the motion. After numerous brands and models of strobes I selected the Neewer NW620 because it did what I needed to do ... use a flash in manual control at a minimum output to eliminate the time for the flash to recharge itself. The flash, the Neewer NW620 out performed what I thought it would do. Using the Yongnuo RF603C II transmitters, I was able to have the strobes (3 or 4) simultaneously flash when the camera was making an exposure. Here are a few examples.

[PC] This works very well to help stop the action on my macro photos. I'm happy with this flash.

[-7 to +120°] This 400w strobe was such a great value packaged in such a great form factor that I switched from another system. I really like that the Bowens mount is built in, the powerful modeling light, the ease of use, etc. Really glad I made the switch.

[1.505 lb] NEEWER Z2-S 2.4G TTL Round Head Flash Speedlite for Sony, with upgraded UI, 2 Adjustable Modeling Lamps, TTL/M Quick Switch TCM Key, 76Ws Speedlight 1/8000s HSS 7.4V/2600mAh Battery rated 480 Full Power Flash (this flash punches way above its weight!)

This is a really great speed light. Everything about it is next generation, and there are improvements everywhere compared to the Neewer Z1 released only a year before. The Z2 has a better LCD screen a modern round head shape, an intuitive menu system and a huge capacity rechargeable battery cell. This flash works with in the entire neewer accessories system and wireless flash triggers.

The improvements over the Z1 are quantum leaped improved although the units look similar. This Z2 speed light works perfect in both manual and TTL settings with my Sony a7cii (only looking a little ridiculous because of the small footprint of the a7c2). If you need a speed light /flash system this is a great one to consider at one fourth the cost of a Sony branded flash system.

The Neewer Z2-S (Sony) works with every Sony mirrorless E system camera. (Both FE systems as well as ASP-C) It comes with a nice storage case, stand, battery pack, battery charger, USB-C cable and instructions with full illustrations. (You will however need reading glasses for the micro sized print.)

The unit's construction is similar in quality to a Sony NG60 sized flash and is slightly bigger and heavier than the Sony HVL-F46RM (25oz v 19oz with batteries). There are slight indentations, when the flash head is swiveled or rotated, but overall, the movements fill tight and well built. The flash has a nice quick release for the hot-shoe. I like the large rechargeable battery pack and never having to deal with AA batteries again.
