Originally posted by pres589 Let's pretend for a moment that money didn't enter into the equation, like you could do a 1:1 trade at a shop; would you keep the DA* 200 if you could straight across trade it for the new 70-210? Have you thought about that one?
Seems like a 28-105 and 70-210 combo would be really sweet with a full frame camera and not too shabby with a crop body (throw in a DA 21 or DA 15 with the crop body just to get some width back if you like)
I can cover the whole zoom range K-1 28-105 and 70-200 with the K-3 and 18-135 when hiking. Too match the DA 18-135 and DA 55-300 you'd have to throw in the 150-450 on the K-1.
The DA*200 I bought mainly so I'd have something when my DA*60-250 was being repaired, obviously the 70-210 is a better back up for that lens. But there are times ƒ2.8 is a wonderful thing, I have 50 2.8, 100 2.8, 200 2.8 and 300 2.8. The DFA 70-210 for the DA*200 would leave a gap there. Currently I have The HD DA 1.4 TC and the F 1.7x AF adapter giving me lots of flexibility inside those 100mm gaps, but they can't cover a 200mm gap if I go from 100 2.8 to 300 2.8.
You really have to look at your whole lens environment to make these decisions. In the scenario you suggest, the DFA 70-210 sounds like a good one. But in the 2.8 scenario it's not so good, at least for me. Someone with 2.8 zooms might see things totally differently, but all my 2.8 lenses are primes.
