Your question is hard to read: So I have taken the liberty of putting it in an easier format for people to follow i.e more spacing. Hope u don't mind:
I am really trying to make some decisions based on the needs I have for my photography but would like some insight from the Pentax community.*
I currently have:
the K-x with a SMCP-FA*50mm f1.4 lens, Tamron 28-75mm f2.8 lens, andd the Kit 18-55mm lens, and I have 3 flashes and shoot off camera flash a lot.* I shoot portraits, baby, infant, couple, engagement, and family portraits.* I will shoot weddings maybe later this year so great ISO performance is important to me.
*So the question…should I keep my K-x and buy a nice DA* 50-135mm f2.8 (either that or the Tamron 70-200mm f2.8 or Sigma 70-200mm f2.8),
sell my K-x (hopefully will get $420 for it) and get the K-r (I like the auto focus assist lamp, better AF, and higher res screen) for $560 (buy.com) and because I’m not having to spend a lot of money I would get another nice telephoto lens as well but not as good as the ones I mentioned earlier,
sell the K-x and get the K-7 (since it’s similar to the K-5 but worse ISO performance and slower autofocus) and get a so-so lens,
or sell the K-x and get the K-5 and just keep the equipment I have.*
There is going to be a trade off somewhere so I’m wondering what would make the most sense based on what I shoot.* What do you all think?
