I'm relatively new to the dSLR world. I picked up an XSi kit earlier in the year that included the kit lens, 50mm 1.8, and the 55-250. It is an awesome kit to start with and I've gotten great pictures with all of the lenses and learned a lot in the process!
That said, I'm finally getting a feel for what I like and where I'd like to upgrade. Couple that with the fact that I'm heading to Yellowstone for a week next month and I'm really interested in grabbing at least one better lens to bring with me. Here is what is going through my mind right now:
-I like the 55-250 focal length and quality and don't feel I can do better right now with what I am willing to spend
-I'm not a huge fan of the 50mm prime on a crop sensor, I find it to be too tight.
-The kit lens has served me well, but I'd like to replace it either completely or add better lens(es) within its focal length
-I don't have the UWA focal lengths covered right now
So here's the problem I have... while I'm in no rush to upgrade my body any time soon, I do see myself going FF one day. It seems like there's a real "battle" between EF and EF-S lenses when it comes to getting the focal length you want with the sensor size you want. I would ideally like to invest in glass that I can keep over the long term and that can grow with me. I feel like my weak spot right now is in a lens to shoot landscapes, which is going to be key on this trip, and I'm torn with whether I should invest in something like the Tokina 11-16 with the future burden of having to sell it if/when I go FF or if I should just grab a nice EF prime like the 28mm 1.8 and stitch panoramas if I have to? I'm a BIG fan of the 24mm-30mm focal lengths (actual, so would be 15-19ish pre-crop) and would be happy to walk around with a prime in that range if it were available on a crop.
To add insult to injury, I have a good friend who is a pro that is whispering in my ear to not spend so much money on EF-S lenses and to just go for something like the 17-40L for now...
I'm sure I'm not alone in feeling overwhelmed and confused by all of these options and their limitations. Can anybody chime in and offer some advice?
