Originally posted by jwc77 I am considering pulling the trigger on a really cheap F35-70mm. Would like anyone with experience to chime in....how does the 35-70 compare to my already owned 18-55mm kit lens? Is it any better...or different enough to purchase? Any advice would be appreciated.
Go for it! It's sharp and agile, my favourite for working in that focal.length range. It's longer and faster than the 18-55, and better-built. It really is like a little bag of primes. Consider that the 35-70 is a 2x zoom, while the 18-55 is 3x. That makes a difference -- fewer compromises. Take a look at the lens reviews. You won't see much hate. My deal: I bought mine on an SF-1 for US$21 shipped, then sold the SF-1 body for US$5, so the lens was damn cheap.

EDIT -- a note on value: I rate value as price:performance. The more I can do, with good results, for the least cost, means more value. My best-value inexpensive lenses are my Tomioka 55/1.4 (US$2.25), Vivitar-Komine 90/2.8 macro (US$3), SuperTak 55/1.8 (US$8), Nikkor 85/2 (US$9), F35-70 (US$10.50), etc. These all give hella performance, especially at their costs.
Comparing new lenses is a whole 'nother thang. The not-cheap DA10-17 was a hella value when I bought it as nothing else came near. Same with the then-cheap-ish FA50/1.4, and the later Tamron 10-24 (discounted). Is that Tamron a better value than a Sigma 10-20 or DA2-24? That depends on price:performance: are they twice as good for twice the price? As noted in another thread, copy variation means that individual copies of each may be very close in performance, so cheap wins IMHO.
