shots missed while changing lenses... not any more.
the tamron 18-250 made me -
- sell my primes
- stop before ordering the da* twins
it wasn't the money, it was the convenience, combined with very nice IQ.
for me, to get top value from this lens, i do this:
- bokeh? get closer & go longer (70 to 100mm for portraits is great)
- extra sharpness? stop her down. though the sharpness wide open (of my copy at least) is WAY better than what photozone.de got - and close enough for me to the primes i've owned, not to be an issue
- high contrast scenes (ie likely CA issues)? stay between 30 and 100mm if it's critical - then no pp required.
for me, all i need is what i already have: k10d, d-bg2 grip, tamron 18-250, couple of 8 gig fast cards, and a af360fgz and a few tripods.
the da* and classic prime glass are great fun, but the framing options the range of the tamron gives you destroys any advantage of the marginally higher iq of the top glass. in prints, and with quality pp, the sharpness difference doesn't exist, even with a microscope - so i got over it :-)
i guarantee that any pro (like ben kanarek) could get exactly the same income shooting this lens, and only this lens for the rest of his career. it's what you do with it, and wasting time and effort on primes means less time to enjoy capturing the moment - though... god... i'd love a voigtlander 40mm pancake... hey, i'm human
