This flash is a perfect fit for my Pentax K1. I haven't used it too much, but I have nothing to complain about so far. It is small and light, just what I wanted. The full power mode, however, is good enough - particularly since the K1 can handle higher ISOs and slower shutter speeds.

Beside my Pentax gear I have a Fuji X100 with an EF-20 flash. Great combo, great little flash.

  Compactness, AAA batteries, power, built in diffusor, quick release

  none for me

Not a bad little flash. If you are a small room with all white walls and and standard height white ceiling it's easy to fill the room with reflected light. It easily fits in your pocket. Just remember it runs on AAA's and not AA's.

I purchased this because I wanted a small light weight travel flash. I also purchased a Vello off camera flash cord to go with it. The bounce flash works ok in small rooms. Off camera this is a great little flash.

  Tilts!, Size and weight, ample power for what it is.

  Not wireless.

Nice compact flash to complement the Pentax K-3 II that does not have a built-in flash. Head will rotate so you can have bounce flash as well.

I searched a nice small PTTL-flash mainly for the K-1.

  lightweight, well build, WR, good vertical tilting, manual mode, seems to support also analog TTL besides PTTL, affordable

• -

  no wireless slave and controller function, no led beam, manual mode only 2 steps: full and 1/4

I purchased this flash for two reasons: its compact and weather resistant design. The only cons is its battery life. Overall, Im happy with it.

Initially bought this item as an addition to my af540fgz version 1.

  Vertical tilt, past vertical. Super easy to pack

  No wireless ptll capability

It is light and small, it only use 2 AAA batteries, very easy to bring it to walk around. It has tilt flash head can flash vertically and even it can tilt to the back to do some reflective flash, much more flexible than the internal flash.

I was able to get this for an excellent price. This is about as good a small flash as you're going to run across: weather sealed, it tilts (but does not swivel), and, best of us, has very ingenious manual functionality (more than it's given credit for).

  Small, compact, ingenious device

  small size makes wide angle diffuser less useful for wide coverage
