Photo Forum / Digital Photography / Digital Photo / January 2007High Definition Opteka 500mm f/8 Telephoto Mirror Lens
I have a Nikon D80 and have some questions re the Opteka 500mm mirror lens. 1. Is this lens fully compatible with the Nikon d80 i.e. does it provide full metering with aperture priority so that only the focus needs to be adjusted manually? 2. Any comments on the quality of this lens and its suitability for the Nikon D80 would be gratefully received. It is widely advertised at about £60, is it a bargain or junk?

I believe that the mount is a 'T' mount and they supply the relevant adaptor to fit to the camera.

I do appreciate that it has only one aperture (F8) but I need to know if the metering works so that the shutter speed can be set automatically in aperture priority mode. >>> I have a Nikon D80 and have some questions re the Opteka 500mm mirror >>> lens.

What does the camera do if you try to take a -picture with no lens attached. I use Canon, I don't know about Nikon, but the no-lens thing and a T-Mount mirror appear the same to the camera. Obviously you won't get an image, but see if you can get an exposure, should be medium gray. >>>> I have a Nikon D80 and have some questions re the Opteka 500mm mirror >>>> lens.

Manual focus. f8 is actually better than f5.6, increased depth of field, much needed. >>>>> I have a Nikon D80 and have some questions re the Opteka 500mm mirror >>>>> lens.

What about my original question #2 - is the 500mm Opteka Mirror a bargain or junk??? > What about my original question #2 - is the 500mm Opteka Mirror a bargain or > junk??? Cheap mirror lenses are in general junk.

Malcolm, Paul is most definitely right... I have a Phoenix Samyang 500mm f/8 cat lens, and it IS junk... wish I'd never got it and used the money for something worthwhile. Like a beer. Oh well, you live and learn... ;-) Cheers, ink > "Paul Rubin" <http://phr.cx@NOSPAM.invalid> wrote... >>> What about my original question #2 - is the 500mm Opteka Mirror a [quoted text clipped - 11 lines] > Cheers, > ink Thank you for that ink, my suspicions confirmed!! Go to pBase and go a search for the lens. There are some sample shots that I think look pretty darn good for a lens with that mm and price. http://www.pbase.com or http://search.pbase.com/search?q=opteka+500mm&b=Search+Photos&c=sp ljc SignatureDo not assume that because I didn't reply to your comments that you are correct or that I am wrong or that I am correct and your are wrong. You can assume that you bore me! >I have a Nikon D80 and have some questions re the Opteka 500mm mirror lens. > [quoted text clipped - 7 lines] > > Malcolm You will have no metering. The aperture is fixed. Bohkah is characteristic of reflex lenses. I have a Russian 500mm/ƒ5.6 and it has very little depth of field. Works in MANUAL only on my D-50. I see no reason why it should not be the same on a D-80. No, the D80 will not meter with this lens. You would need the D200 for that. > I have a Nikon D80 and have some questions re the Opteka 500mm mirror lens. > [quoted text clipped - 7 lines] > > Malcolm |
