Problems with new 18-135 lens on K5Mk2
Mar 21, 2014

I would appreciate advice as to what I or the camera are doing wrong. I have recently bought an 18-135 lens for my new K5 Mk 2. I am having problems with the sky which appears to be melting or layered both in the blue and cloud. It also prints like this. Is it me or the lens? Here is an example

Thanks

Nice photo if it weren't for masses of jpg compression artefacts.  Cant say what you've done for sure, but it could be you've shot in RAW and what you're using is the embedded jpg rather than a RAW conversion, or if shooting JPG you've edited the file and saved it at a very high compression/low quality setting in that software.

This isn't a lens problem. This is a low-quality jpeg problem. It's a digital artifact from making the file size extremely small. Do you have your jpeg quality settings at only 1 star in the camera? Actually this looks worse than 1-star in-camera jpeg, so I guess you have edited the image with another program and saved with low jpeg quality, or perhaps selected an option to force the file size to be low.

Many thanks to both of you. I have just taken this outside the house in RAW converting to 4 star quality JPEG and it seems to be OK. You both hit on the same cause, (operator error i.e. me!)

Very grateful
