Lens Calibrated: Sony E 18-55mm f/3.5-5.6 OSS for NEX

This goes in "profile_sony.txt" in place of the existing block with zeros:

begin lens
group: sonyemount
multiplier:1.5
aperture: 3.5
menu_lens: Sony E 18-55mm f/3.5-5.6 OSS
cal_abc: 18.0 0.025590 -0.086399 0.046144
cal_abc: 21.0 0.031353 -0.089208 0.057472
cal_abc: 24.0 0.034082 -0.098398 0.083739
cal_abc: 28.0 0.012071 -0.027476 0.030799
cal_abc: 35.0 -0.003121 0.025128 -0.016311
cal_abc: 45.0 -0.001392 0.012881 -0.000238
cal_abc: 55.0 0.008579 -0.017748 0.022726
end


Note that this formulation requires the following entry in "profile_sonyemountlenstable.txt" - the file as shipped should already have it:

E 18-55mm F3.5-5.6 OSS|Sony E 18-55mm f/3.5-5.6 OSS

I've done this using PTGui. It seems to work, but as I've taken a different approach to other profile creators, I'd appreciate if someone could test it and confirm that it's ok.

Note that the NEX cameras do not seem to be auto-recognised. I think that this is because the camera ID is in maker notes and not standard EXIF, which is a real pain.

Does this work for the Alpha A-mount version of the lens?

You can try, but I can't imagine why it would work, other than by extreme luck. After all, my understanding is that it's a different lens with a different optical design, even though it's covering the same size sensor over the same focal lengths. It has to be, given the much shorter lens to sensor distance.

You've made a number of posts today that suggest that by doing so your views will come to the attention of Corel. However this is a user-to-user forum and it's unlikely that they will. You might get lucky, but my advice would be to find a way to send them direct. The surveymonkey used to be the official route, but I'm not sure that it's working any more.
