will this also work in a darker environment as far as manual focussing is concerned?

It is darker than the original screen and does help indeed your manual focus but once installed 1 tends to get used to it and to forget about the inconvenience if any as well as to get used to the small advantage it providesIt works and I won't go thru the trouble to switch back. Most of my photography is indoor and lowlight where you need mf

it depends on your lens and how dark the environment is. If you have a 2.8 lens you should be fine. If you have a 5.6 lens and it is dark you may have a hard time focusing manually or automatically.

it works fine as long as your eyes can see it. if it's an environment even af fails to lock on, you are probably better off with liveview + magnification

You'd have to set the light/dark setting toward lighter - if you don't, the B&W; will be mostly dark and you won't be able to distinguish much

I use this on mine and it works on full manual mode. Light meter doesn't work as there's no metering so it does take some experience and guessing. Also just a tip, images are sharper if you set it to f5.6.

It does work in low lighting but it depends on the distance and if its on the manual modes. anything other then the manual...you will get grainy photos.

None at all on my M- it is a bit slow in the focus- but when I combined it with a short loupe to act as a viewfinder it became handy. Mine works perfectly except for the focussing time. VRR

Results are somewhat dependent on your camera. However, I've not had good success in low light conditions especially at high zoom settings.

Yes! Remarkably well! Of course, pay attention to the "day" "night" "stars", etc settings. For most purposes, you'll want to keep the "low light" setting on.

In a fully dark room, once your eyes adjust then this would work. The lighting it very dim. Sorry I cant give you an empirical measurement in lumens.

I don't use dark field viewing as a technique myself, but I have used it years ago in college. I don't think the light source is bright enough for dark field viewing. Sorry I can't be of more help.

I believe it will only auto focus up to 5.6 f stop. Sorry I just don't know any more.

Like the Canon, the lower the light, the more likely focusing will take longer. I found that using the 'focus assist' button (on the camera back - in easy reach) along with manual focus worked best in those conditions.

It should, yes. As others have noted, there will be no electronic control. This means both focus and aperture.

Hello Steve, this is not a good choice for low-light conditions. It only works in daytime, or indoors with good lighting.

Yes/No. You need the lights fairly dim to get a good result from this thing, and if the projector is far from it's screen getting the sharpness narrowed in for text can be tricky. It'll work in a pinch, but a large well lit room would not be good.

Yes as long as it is away from any direct light shining at the project or any light above the path of the projected image. Works well in the dark.

Should do fine in low light too, but adding light will always give you better results.

Not in low ambient light when on either auto or aperture mode; I have not found a mode in which it works well in low light, but haven't read the manual either.
