In camera auto adjustments


3 Aug 2013 1:39PM
My Sony A-57 has in camera auto correction adjustments [which can be switched on or off]. i.e. Lens Comp: Chro. Aber. Lens Comp: Distortion.

This will not work with lenses other than Sony lenses. So for arguments sake, if I wanted to use a Tamron 17-50 no correction adjustments will take place. However, I use a Microsoft editing programme for my Jpegs that has a auto correction facility, would this do the same job as the in camera corrections.

Thanks

No.

are all lens related and specific to Sony camera/lens combination. The camera will pre-programmed to respond to the Sony lens.

Microsoft editing software will act upon the image related parameters such as exposure, colour balance, sharpening etc, it does not know how to adjust for specific camera / lens combinations.

Hope that makes sense.

Thanks, I see what you mean. I will start looking out for some second hand Sony lenses.

Don't the in camera adjustments only apply to the jpgs, raw files are not altered. Software such as PShop/ lightroom will allow you full control of such adjustments including 3rd party lenses to the raw file.

What has RAW to do with the original question?

Thanks all for your input, Yes, they only work on Jpegs, but as I mainly use Jpegs its a useful feature.
However, a good quality lens so I'm told will not exhibit too many faults that may need correcting, although no lens is perfect in that respect.
I did hear that one independant lens manufacturer was going to 'chip' the lens according to its mount, i.e. Nikon, Canon, Sony and Pentax. This is so the camera can respond to the lens. Not sure that ever happened though.
