Excerpt: I just received this unit in the mail, and as soon as I turned it on, the image on the screen was the same size as that of the image on the native camera screen! (The image only filled about 1/2 the screen!!!) I was using the monitor with my Canon 70D (DSLR). I did my own research, and called B&H. Both yielded the same conclusion: apparently not many monitors display video properly with DSLRs...
Pros: Compact Design, Easy To Use, Form-factor, Improves Performance
Cons: Image Not Filling Screen, Limited Compatibility
Summary: As I am getting near 50, this allows me to check focus and color much easier. I also show people their picture and it is easy for them to see. So I bought a second one for my second camera. I use this on my Sony A900 and Sony A850.
Excerpt: Would have been nice for Sony to supply a battery to make this unit work - a big minus to Sony for that. My review: No Sync with Canon G16 although you can view photos taken with the camera on the Sony CLM-V55 (the viewer), but the screen does not appear to work otherwise with this camera.
Pros: Compact Design, Easy To Use
Cons: Limited Compatibility, Pricey, Some Items Not Supplied
Excerpt: I had a problem with the image-size too, using my Canon T4i, and was very disappointed with the monitor for that reason...until today! I messed around with the "info" button on the camera and discovered that by pressing the button a couple of times you can increase the image size on the monitor significantly. This must be some kind of problem with the interface with the camera. Anyway, I'm happy now, but it took me a couple of years to discover this little glitch!
Summary: I purchased this monitor to help ensure the products being imaged with my Sony Alpha were in focus rather than wait for post-processing through Lightroom and setting up do-over shots. The monitor works perfectly with the Alpha and mounts to the camera hot shoe for convenience, but if you need a flash in that spot, you can mount the monitor to a hot shoe bracket off to one side. The monitor includes an HDMI cable and is powered by the same battery that powers the camera.
