Using an after market lens ( Lens correction)

[BADGER.BRAD]

Hello all,

A while ago whilst playing with .raw files I realized (after some help from here ) that the standard kit lens on the Sony A6000 is made down to a budget and it's imperfections have to be corrected by the camera, No such imperfections ever seem to show on my film camera lenses (with them having no options for lens correction) but I I were to buy a super dupper after market lens would it just be really good quality needing no correction or would I have to correct in post ? I'm unlikely to buy a super dupper lens so your information is just for interest sake !

Thanks all.

I think it's becoming increasingly common for makers to make compromises with lenses to enable them to hit more important to them targets such as keeping the weight and / or costs down and when doing this some camera bodies apply corrections automatically and if not they can probably be done in processing software with a lens profile. Even top end lenses may well have some correction applied these days.

I don't know what you use, I convert all my raws to DNG's and process them in Adobe CS5. My Sony camera is probably too old to apply in camera corrections but there are a huge number available in CS5 but even so I do have lenses for which there is no specific profile and if I want to load some corrections it's therefore trial and error and guesswork until I find one that seems to apply good corrections.

I have some old film era lenses, just mass market stuff, Canon FD, Olympus Zuiko, Minolta Rokkor, Nikon, Takumar and others, and although there aren't specific profiles for all of them probably because Adobe don't think it's worth their time and effort to make them there are some, for example there are a lot of Nikon film era prime lens profiles and there may be some third party ones out there. Shots taken with these lenses may benefit from an existing profile to correct the issues which are there if you look for them, vignetting and distortion in particular.

Another point is that for ML cameras the distance between sensor and the rear element is much shorter than for a DSLR so it is easier to design and manufacture the lenses for a given performance. For my DSLR all of the lenses are automatically corrected in LR for me.
