Hello all,
Don't know if this is the right of the Photozone forums to ask this question.
In Lightroom you can choose which lens you have used to correct the lens distortion. I use the Canon EF 28-105 f3.5-4.5 ll USM, but is lens is not listed in the latest(and older) version of Lightroom.
Does anybody know where these plugins are for sale and if there is one for the Canon EF 28-105 f3.5-4.5 ll USM? Or can I use another lens which has similar distortion like the Canon EF 24-105?
Hope to hear from you.
Best wishes,
Reinier
Hi Reinier,
very likely, the changes between the first and the second Make of the 28-105 USM will
not influence lensprofiles ... as you see here ...

... the optical construction is the same.
There is a change in the number of aperture blades (5 -> 7) which eventually makes a difference
for bokeh (and vignetting?).
To see, if the profile of the 24-105 is simillar to the one of the 28-105 (personally, I doubt it), you could try
PTlens ( http://www.epaperpress.com/ptlens/ ). The testversion 10 conversions ... if you convert
the same picture at 28, 35, 50, 80 and 105 with both profiles, you will see the difference or you
will see that the difference is "small enough".
Just a thought ... Rainer
Hi Rainer,
Thanks for you reply and advice. I will give it a try on this website you mentioned.
By the way Lightroom doesn't have a correction profile for Canon EF 28-105 version I and version II either.
Kind regards,
Reinier
