What does that mean in terms of the lens? The quoted spec is 'f/2.5-16' and if that's as correctly quoted as the 1.5" sensor, then based on how apertures are printed on the lens, it means f/2.5 max aperture at the wide end and f/16 max aperture at the long end. I really doubt they'd release a camera that only opens to f/16 at the long end, so I believe that that spec is indicating the total aperture range (i.e. f/2.5 max aperture at the wide end, some unknown max aperture at the long end, and a minimum aperture of f/16 throughout the range - that improves on the G12 which is f/2.8 max and f/8 min).
So, if the Wells Fargo analyst isn't relating the information on the aperture in the standard/conventional way, what makes it certain that the sensor is being specified properly?
Bigger than m4/3? Ok, conservatively slot it between that and the Canon APS-C and give it a 1.9x crop factor. That means a 28-112mm FF-equivalent lens is really a 15-59mm lens, with f/2.5 at the wide end. That means it's got to be substantially bigger than the m4/3 kit lenses, the smallest of which (Oly 14-42mm f/3.5-5.6) is 2.5" long when retracted. The PowerShot G12 is 1.9" deep - do you think Canon will release a G1X that's well over 3" deep, probably closer to 4" deep? If it has a sensor bigger than m4/3, it would have to be...
I completely understand what you're saying neuro, but I'd like to add this for arguments sake:Canon 510HS:
28-336mm equivalent (5.0-60mm f/3.4-5.9)
dimensions: 99 x 59 x 22 mm (3.9 x 2.3 x 0.9 in)
equivalent older cameraCanon SX200 IS:
28-336mm equivalent (5.0-60mm f/3.4-5.3) slightly faster on the long end
dimensions: 103 x 61 x 38 mm (4.1 x 2.4 x 1.5 in)
even older cameraCanon S3 IS:
1/2.5" sensor smaller sensor
36-432mm equivalent (6.0-72mm f/2.7-3.5) a little longer, and faster (1 full stop) throughout the range
dimensions: 113 x 78 x 76 mm (4.5 x 3.1 x 3 in)
I know the physics of lens design has not changed, but they have managed to cram larger range zooms into smaller cameras.
and the Pro 1
that was mentioned earlier in this thread:
28-200mm equivalent (7.2-50.8mm f/2.4-3.5) slightly faster than S3, much faster than SX200 and 510HS
7x shorter zoom range
dimensions: 118 x 72 x 90 mm (4.6 x 2.8 x 3.5 in)
Neuro, I completely agree with you, though, that this is definitely NOT a constant aperture zoom lens.
