When set to 'indoor' shooting mode, the flash points up to bounce light off the ceiling for shadowless illumination of your subject
When set to the 'outdoor' shooting mode, the flash directs light directly at your subject
Built-in diffuser for wide and telephoto shooting:
With the built-in diffuser, the flash illumination covers a wider angle of view or if users want to to shoot at a greater distance, they can rotate the dial on the side of the flash unit to the 'Tele' Position
While the 'Tele' setting reduces the width of flash coverage, it extends the range to illuminate more distant subjects
Easy intuitive operation:
Unlike most external flash units, the HVL-F20M has no dedicated ON/OFF switch
Instead, power is automatically switched on simply by raising the flash unit into the shooting position
In addition, a switch on the side of the unit quickly moves the flash from direct to bounce, making it easy to obtain flash illumination that suits the shooting situation
A charging lamp indicates when the flash is ready to fire
ADI Flash Metering System:
The ADI (Advanced Distance Integration) flash metering system offers the optimum flash metering and automatic white-balance compensation regardless of the background conditions or the subject's reflectance
ADI flash metering works in combination with Alpha cameras and lenses that incorporate a distance encoder
When used with these lenses, the camera calculates a guide number to control TTL (through the lens) flash metering
This guide number is calculated according to distance from the subject, ambient light and pre-flash reflectivity of the subject and the background
Flash Modes: Bounce Upward angle: 75 degrees
Guide Number: GN20
Flash Coverage: GN20 = up to 20 meters (65 ft) at ISO100 with 50mm lens
Number of Flashes: More than 90 times (Alkaline battery)
Power Source: 2 x AAA Batteries; Alkaline, NiMH
Material: Poly-carbonate plastic
Flash Modes: Automatic Light Control
Storage Temperature: (-4 to +140 degrees F (-20 to +60 degrees C)

Great Little PerfomerThis flash is a good companion for my A99 when I don't want to carry F60M or F43M. Works great in small premises, but even better just as a wireless trigger - it doesn't add lots of bulk to the camera. Basically the flash can be considered as a wireless trigger with a bonus - lighting :)
Two the reviewers that give the flash one star - both reviews have nothing to do with the unit features or failures, so not sure about the point of rating a product without even testing it. Just return the flash and get your refund.

Perfect for the A6000A great flash for the A6000, this is my first flash so I cannot really compare it to others but it works great. This is my first flash that lets me take bounce flash pictures. Over the holidays, I took several hundred pictures with it and I have been really impressed with its performance. I used my Sony (CycleEnergy, 800 mAh) AAA rechargeable batteries and they worked great with the flash and the fact that it only uses 2 batteries is a plus since I can swap out them out for another pair fairly quickly.

Nice flash, but poorly constructedI bought this flash to use on my SLT-99V to command my HVL-F58 flash wirelessly. I used it one time in this manner and it worked amazingly well. However, when I took the flash off of my camera, using extreme care as I had been warned about the frailty of it's mount connector, the mount connector separated from the flash and could not be reattached. Upon a closer examination I saw how poorly designed and cheaply built the connection was between the flash's mount connector and the main part of the flash. I returned the flash to my vendor and replaced it with a HVL-F43M, albeit at a $250 cost differential. The F43M has given me no problem whatsoever. It's mount connector is outstanding and seems to be constructed to the level of excellence that I have come to expect out of Sony camera products.. unfortunately I cannot say that about the HVL-F20M.

Good for small placesWas visiting family for Christmas and I did not like the flash results on my A77. I wanted something small to easily take with me and use while taking pictures of family in the house. You are able to bounce the light so that your subjects do not have that glossy flash look. I was really happy with the Christmas pictures. It worked well also taking pictures of groups outside at night close up. The only down side is that after a few shots with the flash it takes some time to recharge. I missed a couple shots because of that. I found that if I shut it off (folding flash down toward the camera) then turned it back on (flipping back up) it helped recharge a little faster.
There is also a etched piece if plastic in the flash that you can turn down so that a direct flash is not so harsh.
Works up to 100 ft IMO but better 75 and under
I did not need any adapter for this to fit my A77. I am pleased with the purchase.

It was good for a whileI bought this flash less than a year ago for my NEX-7. It complimented the camera well since the built it flash is not high enough to get over some of the lenses. Also, it allowed bounce flash pictures. It was a reasonably good flash for it's size. However, within a year it would only take one picture and would stop (batteries were not the problem). I may have taken 40 - 50 pictures with it. Now it does not work at all.

What they fail to MentionI was very excited to finally get an external flash for my camera, as I take many portraits. I have a Sony a65. The description for this item says its compatible with the camera, however they fail to mention that in order to make it work you must purchase an adapter. Thus the flash is useless until you buy an adapter as well.

Outstanding Value and PerformanceVery compact and adds great clarity to my photos. I use this as an add on to my A35 and I could not be more satisfied. Huge upgrade from built-in flash.

great flash, poor constructionI had this flash on my sony rx100. I'm a pro photographer and use a dslr, but also like to have a small point and shoot. This flash really brings the rx100 to a new level and I love the picture quality it gave me. I dropped the camera and the flash broke instantly. I bought a new one, dropped it, and the same thing happened. It broke in the exact same spot, the very thin point where the flash meets the attachment screw. I think Sony should redesign this flash and make this pivot point wider.
Yes, I know I dropped it, but it did not drop very far either time (I'm short...from my hip to the ground), and all of my other equipment has gone through so much more without ever breaking. Probably will not buy a third one. I'd recommend the flash if you're careful!
