Iguana, PenQ7 & Sigma 70-300

Wanted to try out the inexpensive Sigma 70-300 I had lying around; put on the Minolta AF to Q adapter and spotted this male iguana sunning about 35 feet from my position in the park.
I'm really impressed with this Sigma 70-300- just ordered the Tokina 75-300 which is considered the sharpest of all the 70(5)-300 range and will test when that arrives.....I'm looking for sharpness and no visible chromatic aberrations......I will also test my Sigma 70-300 Macro DL which I believe will be sharp as well; more tests coming soon.

If anyone is shooting with one of these inexpensive 70-300's, please post comments on your experiences.

I used to have one. This is one of the few shots I kept that I shot with it. Just was not sharp at infinity.

Are these recent auto-focus lenses?

reh, no they are older very inexpensive lenses that almost every manufacturer makes a version of.......the poor man's zoom.......70-300 (75-300) range......you can find them used from $60 to $150 in various mounts........the Tokina is the one to get (based on reviews) as their version is sharp and has the least CA.........there are new Sigma APO versions which are probably even better but I don't have one so can't comment.

(They are AF in their respective mounts- not on the Q)

Crewl1, that's what some scientists say- I'm beginning to think they were destined to be in Florida as scientists now state many may have arrived here due to past storms that blew them in on sea rubbish from Cuba and beyond- there are just far too many for them to be released "pets" that have bred and multiplied............there are literally hundreds of thousands of them all around south Florida- but who knows!

Yeah the Green Iguanas are common. I put my large pet iguana on the roof to warm in the sun and when I came back there was a Jr Iggy sitting on top of her! lol

I have the Tamron version (Quantaray) which is impressively sharp on APSC, it's a versatile lens, esp for the $20 change I paid for it. Mine has developed an internal problem though where after taking a shot the aperture stays nearly closed (f/32 ?). Dismounting and remounting solves that, but is a pain. From what I've read this is not uncommon. I wonder if the Sigma internals are the same? I took it apart previously (not hard) and I think I see a tab with a spring that I'll have to glue down. Anybody else play with one of these??
