4the skinny on the opteka 500mm
By Raymond Harmacinski
I have this lens and use it on my a100. since its a fixed mirror lens you have to set the camera so it doesnt lens detect. Its an f8 lens if its more than just a few feet away it will be in focus. (focus is adjustable) Also mirror lenses, just like telescopes give you very flat images..No depth of field. But even very expensive lenses aren't much better. So this really isn't the lens for a professional or serious nature photographer but if you need a 500mm lens ocassionally this isn't as bad as all that. This lens is not blurry if you use a tripod or, a monopod in good lighting situations. I doubt anyone can handhold an 500mm f8 lens without any motion blur. If anyone thinks they are going to get the quality from a $75.00 lens as you would a $3500 Prime lens then you're delusional Even a $400 500mm lens will only give at best just acceptable results not much better if at all to this cheap opteka. I have used this lens about 5x in the last 2 years and have gotten very good results. If you have the Sony A-series set to VIVID it will give you good color, If not you can always boost it with any photo editing program. Ive been a professional photographer for 22 years and I know a thing or two about cameras and lenses. If you use this lens properly it will handle your Basic needs adequately. Also the best thing about the lens is that its compact and cheap. If you drop it your not actually going to loose your mind if it breaks.

1Blurry
By Golden Boar
I have the 18-250 mm Sony lens that I bought with the Sony Alpha 700. I was hoping to get sharper pictures of birds. After trying every option that I could think of with this Opteka lens, ISO, tripod, multiple light levels, etc., I have come to the conclusion that this Opteka lens just has optics that are of poor quality compared to what is useful for this camera. I compared several pictures taken with the Sony zoom lens at 250 mm and the 500mm Opteka, and then digitally zoomed in so that the images were comparable. Those with the Opteka were noticeably poorer, even though the digital zoom level was only half as much. To get the lens to work at all on the Sony Alpha 700 required changing the camera settings to allow the shutter to release without a lens attached since it did not recognize the lens. The depth of field with this lens is extremely tight and it is difficult to get the focus right. But even after ensuring that the focus was as perfect as possible, I could not get any better than about the last 6 pixels (ie a 36 pixel square) being about as resolved as this lens would get. Pictures looked fine at 640x480 resolution, but anything more showed the lack of optical quality. Is this what I should have expected with a lens of this price? Maybe, but I was hopeful that it might have some utility even though it would be limited and difficult to use, but even with those limited expectations I was disappointed.

3Requires totally manual exposure adjustment
By Jiminy
It was very unclear in the advertisement how it interfaced to my Alpha 300. I expected that it would require aperture-priority and the cam would set the speed, but that is not the way it is. An adapter is provided for the mechanical lens coupling, but there is nothing except the ring that is camera-specific, and no automatic functions are addressed. That would be OK, unless the ad seemed to imply that it "works" with your camera. I returned it. I can't speak of the image quality because I barely used it at all.
