p.1 #11 · Ok, Will I miss 8mm buying a 28-70?? | |
Yes, you will miss the 4mm in my opinion. In terms of angular coverage the difference is not insignificant (you can look this up on the specs for yourself). My experience with 28mm is that is not quite wide enough for many applications, whereas 24mm works 9 times out of 10.
+3. Every millimeter counts.
In my limited film-camera usage of my dad's 28-70 f/2.8, I found that when I wanted to get wide, 28mm wasn't wide enough, and I'd often switch out "The Beast" for his 24mm f/2.8 prime. (I admit... I was spoiled as a kid by having full access to his lens bag )
On a DX body (which it sounds like you're using if you've got a 10-20 UWA Sigma...), the difference between 28mm and 24mm is a bigger deal... 24mm really isn't "wide enough" for my needs, but a zoom starting at 28mm is just a strange range to be stuck with in terms of composition. The 28-70 is effectively a normal perspective, with medium telephoto reach at 70mm. The 24-70 gives you a hint of wider than normal perspective on DX with the same long end reach.
IMO, you WILL miss that 4mm range, and it's a focal range where if I had a 10-20 + 24-70 setup I'd be switching lenses inconveniently often. Go full frame at the same time that you get the 24-70. Sell your 10-20 and previous DX body to help finance the move.
