I'm going to be testing it over the next few days>>3435851
K1 is a recent purchase, so far so good, if you are familiar with the K5 and K3 theres not much of a learning curve with the UI and menu system but with added controls can be a little overwhelming at first, you really have to sit down and spend time reading the manual, a lot of redundancy with controls but in a good way.
IQ is incredible but I am still getting familiar with performance and testing a ton of lenses, old glass and new. i do a lot of landscape/nature as personal hobby, long exposure, event photography, band photography, promotional and low light stuff. I have a Tokina ATX pro 80-200mm f2.8 that i want to try today, it didnt fair well with the aps-c (it was okay) but wanna try it on FF. Today is IRIX and Tokina day :)
