    Is it Worth it? Opteka 650-1300mm Super Telephoto Zoom Lens

    Hi Guys,

    I've come across this lens and can pick it up for around 140.

    It's F8 - 16 and obviously manual.

    Has anyone come across it?

    I know it's cheap but does anyone think that it could produce some good results and if so under what circumstances and conditions?

    I highly doubt it and F16 you would need insanely bright light or have it VERY locked down and stabilized.

    I came across this lens on ebay for around USD 250 and was highly tempted to buy it specifically for moon photographs...where f/8 - f/16 is usually the norm.

    f/8.0 at 650mm is not all that bad considering many high grade zooms, the canon 70-300 IS for instance id f/5.6 at 300mm... so 1 stop down for double the focal lenght... not all that bad really.

    How decent the lens is optically is of greater importance, and inspite of a lot of searchings, i could'nt find a single review on this lens

    sounds good on paper at least and 1300x1.6 = 2080mm for USD 250 sound very tempting for astro photography

    So who needs a camera when you can get binoculars, or even monoculars?

    Not impressed with Opteka conversion lenses though they made great paperweights until I gave them away. Can't imagine the bazooka would be much different, sorry.

    At f8 - f16 it's an utterly useless lens as you'll never be able to take sharp handheld photos. The lens quality is debatable but I gather they're made in a lock-up garage in Brooklyn.

    Red face Hmmm... a tight pipe with glass on both ends

    Okay ... fair is fair.

    I haven't heard anything substantial concerning this lens other than it has horrible color abberation (CA) and soft edges.

    Have you EVER heard anyone brag about this lens?

    Heck, I'd even entertain reasonable sample shots. What, there aren't any?

    These are so "well-priced", there have to be plenty of them out there ... uhh ...

    Anyone? How about you? Yeah, the fellow sporting the $100 (USD) "No particular manufacturer's name" 500mm f/8 Reflex lens? Any luck with the Opteka?

    Oh well, there you don't have it: Critical acclaim ... NOT!

    Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.
    Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography.
