Originally posted by 12345 Yes, I realize the FOV loss, and I expected it. I have a good wide-angle lens, I'm just looking for a cheapish zoom with as much range as possible. I see that the Tamron 28-300 has gone for as low as $125 here on the marketplace, so the price I found isn't the greatest at $195.
Pretty sure the 10mm difference at the wide end is more *actual* range than the 30-50mm at the tele end. 250-270-300 is 6.2 degrees vs 5.7 vs 5.2 degrees. 18-28 is 73.7 vs 51.5 degrees
So and 18-250 would get you from 73.7 to 6.2 degrees; a 28-300 would get you 51.5 to 5.2 degrees, and an 18-270, 73.7 to 5.7 degrees.
A 28-300 lens is intended as a full-frame version of an 18-200.

Question, though: Have you actually *used* telephotos in the 200-300 range? There's not really all that much difference between 250 and 300. You can simulate the difference right on Tamron's website if you need more visual on what the difference actually translates to.

It's too bad these super zooms aren't 5.6 at the top end... if they were, you could always pack a 1.4x teleconverter and extend reach that way if you needed to. I don't think it'll autofocus with 6.3 though. Could be wrong. Dunno.
