Re: 24-70L ii - Appreciate that IS is not usual for this size zoom.
efs 15-85IS, 17-55IS, 17-85IS, 18-55IS, 18-135IS, 18-200IS,
ef 24-105LIS, 28-135IS, 28-300LIS,
sigma 17-50OS, 17-70OS,
tamron 17-50VC and i'm getting bored of looking already.
a) it's easy to put IS in that zoom range for efs
b) it's easy to put IS in that zoom range for efs f/2.8
c) it's easy to put IS in that zoom range for FF f/4
but somehow a full frame is just too expensive?
Comparing the 70-200s with and without IS isn't so useful, at 200mm f4 iris size is 50mm for a â‚¬500 premium non-IS to IS, f/2.8 size is 72mm for a â‚¬1000 premium. Also, don't forget that price premium includes weathersealing.
The bigger the iris size, the bigger the glass that has to be shifted around in the IS, more powerful motors and complex design.
On a 24-70 f/2.8, the iris size is only 25mm. the 24-105 iris is just a smidge bigger at 26.25mm, both FF image circles.
my price list has the 24-105LIS at â‚¬1050, 24-70L at â‚¬1140.
i'd be guessing a 24-70L II would come in around â‚¬1400 if they fixed the curve of focus back to a plane, and/or the 24-70LIS would be around â‚¬2000...
I see no reason to not bring out both models, a basic economic principle is to fragment the market and get more sales in, people who want IS will pay for it, people who don't will pay less and get the nonIS.
