Well I'm baffled! I have been using my 800mm mirror for about a year, Taki g great pictures! Although the construction quality of this lens needs improvement it does normally work well. I was at a "long boat" meet yesterday of Prep schools and thought I would surprise them with photos of the meet! I had nothing but trouble! My D5200 just would not work with the lens! All I got was white outs! When I came home a bit dejected, I went out in the back yard and took some good shots! I am thinking that the combination of bright sun and water did me in. I tried every setting of iso the camera offered (100-6400) but it didn't matter. Any suggestions? They are coming back in a few weeks! This is not a paying job, this is for the kids!

You know the fixed f stop of the mirror lens, so exposure will be controlled by shutter speed and ISO setting. It sounds like this may be a lens flare issue? Your location in relation to the sun may be the issue. Tent or scrim your lens from overhead sunlight. Change locations to see if the angle to the sun makes a difference. You can practice these things these things at the lake with or without boats!

Thanks! Yes I know it has a fixed aperture (f/8), and I will check out your suggestions this afternoon as the sun angle and light will be the same! Not so for the next week, rain coming! LOL again thanks.
