I have a Nikon D3200 DSLR. I know the Pro-Optic 500mm Mirror lens is manual focus and I believe fixed aperture at f/6_3. If I put the D3200 in "Aperture Priority Mode" will the camera light meter adjust the shutter speed to give correct exposure? Or must I operate the D3200 in Manual mode and select the shutter speed myself. Thanks, Jon D

Jon - Sorry for the delay. Been traveling and didn't have my ProOptic 500mm with me. I just tested your question using a Nikon D300 and in aperture priority mode it did NOT automatically set the shutter speed. Not sure if your D3200 will work or not. Checked the Instruction Booklet - here's what it says.
"Both aperture and shutter priority automatic cameras will automatically set the right speed with its auto exposure mechanism, except a few models which it is necessary to operate on a manual function."
Suggest you see if you can contact ProOptic and see what they say. FYI, don't expect anything close to the sharpness you get with Nikon glass. I strongly recommend a tripod, or at least a monopod.
Hope this helps.

I use the Pro-Optic 500mm on my Nikon d40X in the manual mode only. Nothing else works, aperture, speed automatically. I also only shoot with this lens on a tripod. It is almost impossible to hand hold without camera shake.

I use it with a D300 and have used it set with my camera in Aperature mode.

I did buy the lens. The Nikon-3200 says "no lens installed" and will not take pictures in any mode other than "Manual". Aperature mode is deactivated. So I have to set the shutter speed, look at the result, and guess again. The camera will not use the built in light meter and adjust shutter speed itself. Otherwise the lens performs as advertised. As expected it is VERY sensitive to focus (and vibration of course).

I use a Nikon D300. The mirror lens is manual. If you haven't already, go into your "setup" menu, select "non-CPU lens data", enter the focal length and maximum aperture, then scroll up to "done" and hit the ok button. This way you can operate in Manual mode and know what shutter speed to use. If you have more than 1 manual lens, you will have to number them. I do not believe you can use this lens in aperture priority mode, at least I have not been able to. Hope this helps.

Jon D-
You are correct about this lens being manual focus with a fixed aperture. However, the camera will not recognize this lens electronically in any of the auto modes. You must set your camera in Manual and select the shutter speed, as you thought.
I bought one of these lenses, and was very satisfied, using it on both my Nikon D40x & D90.

I have a Nikon 300s and when I use the 500mm lens I set the camera to full manual. Take a look at the screen to see what I have and adjust as necessary.

The Pro-Optic 500mm f/6.3 lens works fine on my Nikon D300 in Aperture Priority. Mount the lens then go into the camera menu for Tools/Non-CPU lens data and tell the camera software that the lens aperture is 6.3. If you put on another lens then later remount the Pro-Optic, the camera will identify the lens and remember the data you entered about it.

I have a D300s and that's what I used. I almost always use AP mode and it works well. This lens is best used with a tripod for steady shots and for focusing as at 6.3 the dof is shallow at the closer distances and needs to be spot on.

I just tested with my Nikon in "Aperture Priority Mode" and the camera light meter will adjust the shutter speed for exposure. I did not calibrate the accuracy of the meter reading with this lens however.
