okay, i've been shooting with high end "prosumer" p/s cams for quite some time now and now that i've jumped into a dslr i'm trying to figure out what best suits my needs. basically i am looking for ideas/suggestions pertaining to good walkaround lenses. lately my 50mm has been heavily used but i find it a bit awkward at times when its not quite wide enough and i have to painstakingly re-position myself or re-compose my shots. these are problems that i never encountered having used 10x, 12x, & 16x optical zooms on p/s cams. i know alot of people would say that that's where the real creativity comes in and i do believe that but i think a different lens may be better suited to my everyday needs. i haven't decided whether a zoom or prime would best suit me. i mainly shoot architecture and landscapes. another favorite subject is urban blight (we have tons of that here in philly). and to be quite frank, anything of L series quality (and cost) is not an option at this point in time. the kit lens does a good job but i am leaning towards a prime lens. primes are cheaper and faster and that matters a bit more to me than super telephoto capability. and last but not least, i'd like for my next lens to compliment the other two as far as focal range is concerned. so what are you guys toting around everyday and why do you love what you're using?
