Re: Policar
Yes, would be great to have a 17mm TS-E or even the Zeiss 21mm I keep reading about. For those
prices though it had better grow arms and legs, walk out and pose every dang tree and bush for my
landscape photo, walk back, mount itself on my camera body and reach back and hit the shutter release.

Of course that's fantasy and it's nice to hear about those sorts of lens but they are totally impractical
for lego_boy's or my budget. Currently I'm about at about his budget going towards a EF 20mm 2.8 early next
year.
I would have to greatly disagree that his or my own budgets make getting a lens impossible. Challenging
perhaps but not impossible at all. I've been doing quite a bit of research and I'm still looking at adapting
an M42 mount, for $50US and $10 for an el cheepo adapter it's right in the price range my wallet likes.
As for other options; the 2 lenses I've also been looking are the old-ish Tamron 17-35mm f/2.8-4 and the
Canon EF 20-35mm f/3.5-4.5. Both seem like decent lens from what I have read. When they are available
the Tamron is less than $200US (about 130GB) and the Canon less than $275US (about 180GBP).
Don't be intimidated by having to adapt and old style lens. Canon's EF mount being as verstile as it is and
in our budget range it's actually a very real option.
