| p.8 #8 · Sony Full Frame attack: (SR5) Three E-mount FF to come within 5 months! |
Agree with the logic, Rich. And it makes sense for Sony to do so - maximum flexibility in both directions.
'A 24-70 f/4 zoom would seem a good choice because it would be lighter than 2.8, and contrary to popular belief on modern photo forms f/4 is quite servicable'
The key to this lens design is that it must perform very well right from f4, in the way the older slow max aperture CY lenses did: 35-70/3.4, 80-200/4 and 100/3.5. [It was interesting to see Phil Reeves' fine tests of the 16-70 do poorly at f4, I hope we see this kind of test on a good copy.] They will know users will be looking hard at the FF corners so a slow lens will help get that right also.
Hooligan, it really has to be much much better than the wider range Canon 24-105L. Very different design parameters, different and very discriminating audience, no faster star lens in the lineup, almost certainly Zeiss recent asph development. I hope it's quite small/light too - 350-375 grams.
It can't quite be at top end prime level performance, but it is the most important lens for them, the way to get people out of their DSLRs is better quality in the bread and butter offerings they can afford and want to use, maybe exclusively.
