I have a very nice DAL 55-300.. but like all lenses it isn't perfect.
No quick shift, which I find useful. Also 58mm filters, of which I have but one - but I have several nice 52mm filters for various needs. So I search high, low and in between, and finally find a well-priced DA 50-200.
Not the WR since that takes 49mm filters
(why Pentax, why?) - and
not a DAL despite bargain prices, I really want that quick shift!
But as the 50-200 approaches, I wear myself out wondering. I have a Quantaray 100-300 so no focal length is lost, just another lens to change when needed - and when I don't need 200+ I have a very nice and compact lens in my pocket. But how many of us know when 220mm is ideal, in advance? And can't I just buy another filter or two and be happy without the occasional quick shift? After all the 55-300 has a great rep, and I know from experience that it is well earned.. plus it's f/4.5 just short of 200, so a bit of speed gain for a few grams. I've found myself to be a real gram counter with cameras, but on yet another hand I went from k-x to k-r and put on a few grams with little complaint. And I had the WR 50-200 with my K-7 and liked it a lot.. except for those 49mm filters I don't own. And if I keep the DA and sell the DAL, it frees up some funds for the next obsession..
but it could be cheaper still to buy two or three 'decent' filters (and oh yes a hood!) and refuse the 50-200 so it goes back unopened.
Or I can let it in the door, take the two lenses & test the stuffing out of them before the return period ends. Thing is I suck at lens testing, it always seems that or more variables are varying due to my lack of foresight. And in the end it's always very close unless a copy is just bad, which I've seldom encountered. As of 4:30 Friday that's the plan (give or take the 'rigorous' tests
) .. but it's a risk! It wouldn't be the first time an either/or decision comes down to 'heck why not keep them both?' - that path has deep ruts from my taking it so often.
Not expecting any wisdom from you folks that I haven't heard before - just thought I'd share my story and you can shake your head in sympathy
... and count how often you've done this very thing. If you can honestly say you haven't, you have my deep respect! And some day perhaps I can share this story with DA* in place of DAL, perhaps
but today is not that day.
