I've been saving for about 8 months to buy a must have lens to add to my gear. I currently have the 50, a sigma 17-50 2.8, a canon 24-70 3.5 and now, as of next wednesday, I should a spanking new 70-200mm 2.8 L. I'm feeling a little bit of guilt for the purchase as this lens will cost me more than my body. I spent the last few days trying to convince myself that I didn't need it and I should just save the money. In talking to a couple of professionals and getting their feedback and also talking to other amateurs, I got some mixed signals. The pros tell me that it is a must have lens for wedding photography, sports photography and wildlife, the amateurs tell me that it is not worth the money. My wife is very supportive of my hobby and she understands that it is something I love.............I love her for that. I want to go all the way with this love and I feel like I'm taking the right steps. What do you guys think? have you guys felt same feeling of remorse when making a big purchase such as this?
