I've been toying with the idea of replacing my Canon 55-250 & Tokina 50-135 2.8 with a Canon 70-200 F4is (or even a Sigma 50-150 OS 2.8) and welcome some input. The Canon 70-200 2.8IS is beyond my possible budget. I've been going thru my pics from the last 6 months and find that in about 80% of my shots/keepers with both lenses, that I am living in the range above 75mm and below 200. In this range, my soon to be 3yr old is my main subject, but throw in some landscape and close up stuff as well. I shoot predominantly outdoors, but even indoors, and to my surprise, I found the same exif results. The kicker though, is that with the Tokina, I am shooting mostly 3.2 to 3.5. I've shot several times limiting myself to f4 to see what would happen, and was not unhappy with the results...but obviously 2.8 is quite nice to have.
Both lenses are excellent, very sharp, and free of any issues. I'm looking at this for the following reasons:
1. Consolidation as the 55-250 tends to be largely unused, but it's nice having the extra range and IS when I need it.
2. A gain in IQ in the range above 135
3. IS and USM across the range.
4. There are times 135 feels to short on the Tokina, the extra reach in a single package is appealing.
My main concern is loss of the 50-70 range and being limited to F4, but wondering (as a hobbyist) if one or both of these is truly a concern, and if there are other factors I may be overlooking. I'm not looking to collect lenses, just have the tools for what I need.
Do I sit on what I've got, make the change, or consider an alternative?
