I have seen opteka lenses lately but have not seen any pictures from them. How do they rate? Are they reasonable quality lenses?

I have the Opteka battery grip and really am impressed by it, are the lenses comerable in quality and IQ?

Opteka lenses are just organized coke bottle bottoms.

someone bought the 650-1300 one, they said it was OK for the price, but pretty soft

The 500mm preset (NOT MIRROR) is meant to be OK for the price, although not below F8. A few people have those and will swear by them.

The 500mm mirror lens is a piece of junk

The 100-400 lens is also a piece of junk.

In the case of the mirror lens, someone got sharper pictures by taking a picture on a similarily priced 70-300 and upsizing it. They even got sharper pictures upsizing a 200mm lens.

In short, only buy the 500mm preset and the 650-1300, and even then, only buy them if your pretty short of cash. In the case of the 500, you'd get better performance with a 70-300 (sigma's good) and a cheap kenko teleconverter.

The 650-1300 needs a tripod, but I guess it could have a use for some people?

I am looking for a longer type lens. I wangted to make sure I wasnt waisting alot of money when a much cheeper lens would do the trick.

Can someone post some pictures taken with the 650-1300?

search the EF section for 650-1300. I believe pcasciola has one, but I PM'd him a while ago and he said he hadn't made many shots with it.

Its only real use is static wildlife, moving wildlife on a very bright day and the odd paparazzi type "snipe" shot. From what I've seen, its huge :D

Thanks for the links...those are not bad!, I just have to think whether I just want to pull the trigger and get the real thing, or go with a "just OK" long lens...

What are my options? What other good long lenses are out there?

I aways heard that Opteka/Cosina/Vivitar/Phoenix lenses are all made by the same Company and then rebranded. Not sure if this is true, but the lenses are pretty much all identical in appearance.

They sure all look alike. And are all priced alike. I bet they are made by the same people...

I'm one of those that has used the Opteka 500/8 'preset' manual focus lens.
It gives quite usable results .
Leo described them very well i say -most of the opteka's are horrid.From images others have taken i say only the 500/8 preset lens is worth bothering with.
And i'm sure james is absolutally right about several of the brands being from the same factory.

I'll see if i have any example pics online from the 500/8 lens

I don't think you should bother with them... maybe get a Sigma 70-300APO like mine for really cheap (~$150) and using photoshop/geniune fractals to upsize and crop the image. Chances are, you may get very similar quality images for cheaper.
//edit: I just noticed you have ...
Canon 70-300 4-5.6
Sigma 70-200 2.8
Sigma 170-500.

I believe if you take your Sigma 70-200, slap her on a tripod, MLU and stop it down to about f/5.6-f/8 and crop a "630mm" or longer from the image.. you'd get a sharper picture :D

These were taken with the opteka 500/8 lenson a 300D.All at f11 (i think),all handheld/braced.This is the lens in question (not the smaller mirror lens!)-

when I win the lottery, I'm going to buy one along with my 1200mm f/5.6, just to look amazing!

(in fact, I'll buy 10, and give them away to people)

Wouldn't that be considered cruel and unusual punishment?:lol:

Actually the 500mm mirror lens doesn't seem to do too bad considering.
