Shot with 6D + 24-70 f4L @ 40 mil. A hand held five frame panoramic.
A really good lens, sharper across the frame than the 24-105, small and compact, feels like a large prime on the 6D, but looses the 80-105. Hmmmmm..............................................
Sporgon, if you had to pick one which one would you choose? 24-70 f/4 or 24-105 f/4?
That is a tricky question, made all the more difficult by the fact the 24-105 can be bought so much cheaper despite the RRP being similar.
If I wanted a general purpose zoom that was relatively small and had IS to give me as close to prime quality as was feasible, and I was shooting pictures made up of a single frame (which most people are) I would be willing to loose the extra focal length and cash and get the 24-70 f4 L.
However if I intended to use primes for critical, planned work, and use the zoom as a 'walk about', more casual lens I would go for the 24-105 and gain extra length and cash in my pocket. I might add that vertically shot stitched frames with the 24-105 @ about f8 are as good as any other lens, certainly in the print anyway.
