Sorry if this is in the wrong forum, but you can't always blame the newbies
Anyway I'm currently looking at obtaining a Pentax k-x, as;
1. They are cheap(about $630 off ebay)
2. They have loads of glass, both new and old
3. They run off AA batteries(I'd like to go bush or travel with it whenever I can(and AA batteries can be found everywhere), and
4. It isn't a Canon or Nikon(lol)
To skip to the point, I'm looking at either the Tamron 70-300mm or the Sigma 70-300mm, both f/4 - f/5.6. They are both pretty much the same price(Tamron is $190 + $30 shipping, the Sigma is $200 + $20 shipping). I suppose the questions are;
1. Which gives a better photo quality?
2. Do they both support manual aperture adjustments/focusing?(I dislike AF with a passion, as it rarely works when I need it to).
Obviously the budget is around $250, but the Tamron appears to be recommended around here, so for curiosities sake I guess.
Thanks. If it has already been asked(probably) feel free to link it for me
