slightly puzzled

err sorry George I should have mentioned that bit

Your right John a couple of them do look similar.

Probably out having fun somewhere. The ones I have met have a commendable knack of doing so.

The only non SMC F versions I am aware of are the 70-200 and the 28-80.

If installing new lights in the Kitchen and removing a fireplace from the living room is considered fun, then yes I am having a wow of a time

Thanks, guys. Clarky. I know your enjoyment... I am putting in a whole new kitchen at this time. I realise that the A version is built like a tank but the F version is tiny in comparison, so easier to carry. With the A version, plus the F version plus the Sigma 35-105 coming somewhere between the two I am not sure which to keep and which to sell. Where is the world wide button on the Ebay site? Have entered ebay.com and tried to find the F lens there but still no joy. apologies for being such a pain.

It runs down the left hand side of your browser under preferences. You won't find the worldwide button on your summary page though, you have to run a search first, then look under preferences. I hope I explained that right

I have a Pentax F 35-105mm boxed and never used, so I can't help you with the IQ but it is quite small, I would keep it instead of the A version just for that reason alone.

Heres mine, such a pretty lens

I agree. It is a nice looking lens and easy to carry. I also have the F version of the 24-50 F4 and I like that a lot. The F 70-210 is covered by my DA 50-200 and so that must go. Still searching for a price guide for the Sigma 35-105 3.5/4.7. Must try the worldwide E.bay. Thanks for your guidance. Hope your homework progresses without injury.
