Re: Opteka 650-1300mm High Definition Telephoto Lens
VOICE OF DISSENT !! THEY'RE GREAT !! I looked at these a while back and decided the cost was too high for what has to be junk, then I spotted an ad for an Opteka 500-1000. On reading closely I found that like the 600, the 500 comes packed with a x2 converter, but could be bought without it. As I already have a x2 converter i took the plunge and paid about £80 to 47st.photo on eBay. My lens arrived in a few days. I had to give the courier just short of £10 for Import Duty so I spent £90 in total. It isn't complete junk and performs OK. It's totally manual, not great at extreme distances, but not the complete pits either. F8-F22 so yes you're looking for good light, but you can shove up the ISO. Use a tripod for preference, but you can handhold and jam yourself up against a tree or a lamp-post or something. As long as you don't expect top class results, you should have good fun with it.
I think I've posted these images here recently already? The swans are 500mm at about 50 or 60 yds, 10 or 12 feet apart, focus on the more distant one, DOF clearly visible between them, the mountain, Slieve Donard in the Mournes is 1000mm at about 25 miles. I think I had the ISO quite high. There was a bit of haze as usual in the evening but the Mourne Wall is clearly visible running up to the top of each peak and the triangulation pillars atop these mountains can also be seen. They're built out of granite blocks and would be about 20 feet high. The dove is I think 500mm at about 20 yds handheld with me jammed up against my back door. The other two were taken on tripod with a beanbag draped on top of the lens for extra stability. I'm sorry now, that I didn't buy the 600mm, but I decided the 500mm at £80 was less of a loss if it did turn out to be rubbish, but I'm well pleased with the results I'm getting. Alex.
