A tough decision, why not buy an adapter to fit the 17mm to the Canon 500D. You should get manual focus and exposure the same as with a Pentax DSLR at a fraction of the cost, you could always upgrade to a Pentax later when funds permit.

If it's a clone of the Teleplus Pz-AF 1.7x SHQ it'll be very decent IMHO.
No idea on price I'm afraid.

Hi Guys,
I'm having another senior moment so apologies if the answers should be obvious.
I have a Sigma 70-300DG but as you know this is macro 200-300mm only
So I've been looking at lenses (circa 70-110mm max) and havn't yet descided on a macro or a zoom. Or are there any which do both over the whole range
I like the idea of a macro so (for exaple) I can get shots of insects easier, but a zoom would give me a bit wider scope (maybe).
Anyway to the actual query
What do all the codes mean that follow the sizes eg
Pentax - DA; DFA; WR
Sigma - DG; EX; DC; OS
Tamron - SP; DI; DI-II; LD
Not an exhaustive list but I'm sure you've come across these and more.
Is there a listing anywhere that will explain these?
Are they (for the sake of argument) irrelevant and that any will suit a K10D and work beyond my capabilities?
regards
Bernard
DFA: digital and film full frame.
WR: Weather Resistant
DG: APS-C and full frame, digital coatings (optimised)
EX: Professional designation.
DC: Digital only.
OS: Optical Sableiser.
SP: Super Performance (pro grade lens)
Di: APS-C anf full frame (optimised for digital)
DiII: APS-C Digital only
LD; Low Dispersion glass elements

Thanks for the comments, I was actually tilting the camera as I took them trying to get a better composition on the Damselflies but resisted the temptation with the 4 Spotted Chaser as they do tend to be easily spooked.
Regards,
John

Glad to help, hope you can find what you are looking for, maybe Ebay would be a good source if it is available to you.
