Originally posted by Si1maron So, I own a K-x and lately, I've been not satisfied with my flash sync speed issues, which surprised everyone in the service centre. So, I decided that I want to change body. There is a K-5 which costs like my K-x, but I won't have any money for it in nearby future. This K-5 has troubles: crack on the viewfinder(covered with magnifying cover), bayonet release button is lost(i have a friend with 3d printer, so I doubt it's a problem) and the mode wheel occasionally won't turn, or turns not very easily. Aside from that, it works perfectly and has only 50k shutters. Should I trade my K-x with it's flash sync toruble for a better, but little battered K-5?
I won't be able to save any money in nearby future, sadly.
The first few runs of K5 had a host of problems. The one you are looking at has the very common button falling off problem, which isn't solvable with a new button as it's a design fault in the camera. You have also noted the mode wheel problem, which can also manifest as the wheel turning but not actually doing anything useful, like changing a setting.
In addition, the early K5s had problems with accurate auto focussing, and the sensors would develop spots on the inside cover glass that could only be solved by replacing the entire sensor assembly. This wasn't necessarily a Hoya QC problem as the entire assembly was supplied by Sony, but it was still an issue with the camera.
I suspect, given what you are seeing in the camera you are looking at that it is an early run camera as eventually Hoya did sort of most of the issues.
If you want to see what you might be getting into, go to the K5 specific forum and start looking at the really early threads from when it was first released in 2010.
For myself, there isn't a barge pole long enough for me to risk my money on a K5. Look at a K5II instead. They are Ricoh built, and they put adults in the room, something Hoya didn't bother doing.
