Is the image quality affected by the bit of glass in the adapter? Is there any lose of light with it?

Not that I can tell. That glass is designed to achieve the infinite focus. Without it, it wouldn't be possible.

It is really hard to tell whether it is the adapter or the lens itself. The images I have taken so far are reasonably good. I am using Vemar and Mamiya lenses from my film days. If the old manual lenses you have are of good quality you are likely to get good images. There doesn't seem to be any drop off in light transmission. This adapter has a single, clear piece of glass in it so light loss, if any, should be minimal.

When adjusting aperture ring and you're zoomed in you will deal with vignetting, other than that no quality issues

Not really ... the LEDs aren't quite bright enough and it will really depend on if you have anti-glare glass.

Yes, I have done so. The IR's at night will not shoot out properly and you will get a reflected picture. During the day, it is hit and miss depending. I have tried this with several different types of glass (dual pane, single pane, etc.) and when I have looked at the quality of the video, it is poor. This method also relies on how far away you set up your camera from the window, and the ambient lighting surrounding the area as well.

Teleconverters usually work better with faster glass but if you have lots of light should be no problem. Use a tripod as you take a 300 on a Cmos now your at 450 and add a 1.4 at 675

The image is pretty good. I don't notice any bluriness, the only spot it loses detail is the very brightest part, because I adjusted the image settings to show more shadow detail. Zoomed in, sharp lines are just 2-3 pixels wide. Small details in the wall texture or tree trunks show just fine. At night it shows a good image under street lights, but note that it is not infrared or "night vision."

I can only tell you what I know from experience. Light can make viewing clearer if it's far from your viewing, but close light can hurt your eyes. Whether or not it can damage the device, I don't know. It says if you power it up in open light, don't remove lens cap or it will damage the device...I'd say email the company directly but it's probably impossible to get an answer.

The adapter fits beautifully, but the quality of the image was fuzzy that it could not be used. It was not an issue of focus but the optical quality of the glass inside the adapter. I was very disappointed that I was unable to use this with my minolta/sony lenes. One thing to consider is that I bought the item used and could have been this particular adapter was defective. If you purchase one, I recommend buying a new one only. Please give us a report of your experience if you do. Thanks

It isn't bad in low light, just use a wide angle lens to use as much light in the area as possible and you shouldn't have any problems.

Not really- it largely depends on on your lighting.You certainly cannot see detail through it

Certainly not for me, I could not justify the reduced light transmission of the APD filter. I use this often at f/1.2 and the APD version may be worse than f/1.4, some say 3/4 an f stop. Personally I thought about changing until I saw the impact on light and a rendering that i did not prefer.

I'm just an average user, but I think the quality is just fine. I did not notice any change in brightness/clarity of the picture.

Hi. I ended up returning it since the quality of the image was so poor compared with what I was used to.

No, you need to spend a few hundred more dollars for something like the Metabones Speed Booster and I haven't noticed any light loss in really use. But, I don't pixel peak or run complicated lens tests to check.

The adapters with glass will allow you to focus to Infinity, but with some loss in image quality.

We'll I'm not sure if you mean "image quality" as in taking pictures? Or as in the screen. And we'll the plastic is only on the back side and it has a a part cut out for the mic, camera lense, and flash. So in answer to if it affects "image quality", no. You will notice nothing at all.

It does better than comparable lumen models I have owned. The lighting location matters, I.e. if you turn on a lamp on the opposite wall you'll see very little change... but if you turn the overhead lights on near the screen it is considerably washed out. With my mini blinds closed in the middle of the day the picture is still very good. Short throw does matter I believe. Not sure if I'm saying this correctly but I believe the closer the source the less effect light pollution has on it. If your looking for a projector to use with over head halogen lighting you'll need a significantly higher lumen version. It does better than comparable lumen models I have owned.
