Re: phototgraphy tips if u can
I've not used either of these, but from what I've read they are very capable. Basically considered entry level dslr and either should be good. There is a bit of a learning curve when jumping into the dslr world, but nothing too complicated and it just takes a little time. A lot depends on your budget and then which lens you put on it. The dslr world "can" get expensive. The kit lens is generally the efs 18-55mm f3.5-5.6 and will add about $100 to the cost of the body. Not too bad of a lens for the money. Some get the ef 17-85. You hear good and bad about both.
The differences that I'm aware of are :
XT - 8mp XTi - 10mp. Not a huge difference, the 10mp will give room to crop and may be able to print just a bit larger. My 20D is 8mp and I've printed 20x24 with no problem.
Focus points : XT -7 XTi - 9. Again nothing deal breaking here. I typically select my focus point, so this is a moot point to me.
LCD : XT - 1.8" with 115,000 pixels XTi - 2.5" with 230,000. XTi is clear winner here. Very nice improvement.
There may be some other improvements in the XTi as it's newer. It'd be best to go to the store and hold them. A whole nother world opens up in the lens department.
