Originally posted by Douglas_of_Sweden I'm not gona talk you out of primes since I favor primes myself, but you are overestimating the size of the DA*50-135.
I've handled it some, and I thought it seemed uncomfortably large and heavy for regular use. The question in my mind was whether I'd get used to it. The Sigma 600/8 seems to be telling me that no, I'd probably continue to find it uncomfortable. But I'm an unabashed small lens junkie.
Quote: the DA*50-135 must be a much more versatile tool, and not be heavier, but lighter, than most combo of three primes that would cover the same range.
Actually, according to the specs, it is heavier than the combined weight of the *four* primes that I normally use to cover that range - the M135/3.5, M100/2.8, DA70/2.4, and DA40/2.8. That's a pretty impressive statement on behalf of the primes, actually.
And I don't normally use all four primes in that range - often I'll just use one or two of those, and virtually never have more than three of them with me. So I'm *way* under the weight of the 50-135. And even if the 50-135 were marginally lighter than the lenses I have with me (which it isn't!), it's not the combined weight that concerns me - it's the weight *on the camera*. No getting around the fact that the 50-135 is like having all four primes mounted at once, rather than one on the camera and the rest in the bag.
Anyhow, I could see it being useful in situations where I'm shooting professionally and under pressure to get certain shots and feeling the need for more than two primes and being slowed down by lenses changes. But under normal circumstances, I'd prefer the primes. If I won the lottery, I suspect I'd buy the 50-135, but leave it at home more often than not.
