Finally, after just over two years using a Canon S1 IS, I have the chance to step up to a DSLR. I have been using my S1 mainly for macro shots, since I attached a Raynox DCR-250 super macro. My main line of work is macro photography; I don't make a living out of it, but since I'm working in an entomology lab it's very useful, and generates some extra income. I'm planning on buying a Canon Rebel XTi with the 18-55mm kit lens, a 100mm macro and a Canon ring flash (the MR-14EX macro ring lite). I already have ~4GB in CF cards from my S1, so storage isn't a problem, and that setup fits my budget just right. I was hoping to get the 40D and the 100mm macro, but I prefer getting a good lighting setup. While I'm sure I'll be using my 100mm macro for the great majority of my shots, I'd also like to take pictures of landscapes, portraits of my friends, family shots, etc. I was considering replacing the kit lens with the Canon 50mm f1.8. Is this a wise choice? Are there any other lenses that I should look at? (please keep in mind that my budget is pretty much set on the $1500-ish that the current setup costs, so I'm not expecting anything besides the 50mm) For me it's a toss-up: I like the versatility of the 18-55mm range, but I'd like to take indoor (ie. low light) pics, the greater DOF control of the 50mm is nice and from what I've seen it's sharper. Although I'm pretty spoiled by my 10X zoom, I could very well adapt to "zooming with my feet" Thanks for any advice, and any other tips are well received!
