Would greatly appreciate comments regarding the clarity and sharpness of the lens, as I can still return this lens for a full refund. Will post some more during the next couple of days to get feedback.
A fair test would be without the tele-convertor. Honestly, tele-convertors are only good with fast lenses, and I'm afraid the Tamron's f5.6-f6.3 is a little slow. Although I am happy with my Tamron, it creates the sharpest images with good lighting, and the 1+ stop hit with the teleconvertor might be too much. Tele-convertors of any kind will degrade image quality to a certain extent. With top quality primes this is not significant, but other than that you may have problems.~onlybill
Thank you for your informational comments. Yes I made a mistake in typing 750 instead of 700. Please remember this is the eager to learn thread and I'm not aware of what IMHO stands for.
But thank you again
Hi Oscar Agree with the suggestions of 100% crop for evaluating Can take a area and save it a t 100%
Remember you have lots of magnification without the converter 500 + the camera crop factor is 750 Anytime you go with the converter the image will be degraded how much is just a test away. Take a target which could be a poster with writing them make images at different focal length wide open and one stop close. You will know if it works or not.
The posted image looks fine and could have come out of any prime lens. when you blow it up for printing etc will be a different story !!!
Hey Oscar,
I like your duck...:p:D To me it looks fine but I would do the newspaper test that Al suggested at various focal lengths, tripod mounted of course...:D The lens feels very light to me. Do you like it?
