Originally posted by jab2980 As someone with a K-5II, has never had a problem with low light AF, doesn't worry much about WB until editing in RAW, and doesn't use AF points (manual or focus and re-compose), would there be any advantage in upgrading? The only problem I've ever really run into his how slow AF-C is... I have many pics of my dog running at me where only his tail is in focus ....The recent K3 price drop sparked my interest.
I use both k-5IIs and k-3 and both bodies are usually available and the one I always reach for first is the k-3. Not sure I can say it would be worth it to you to upgrade, the k-5IIs is an awesome camera. But, the k-3 is better.
Reasons I like it more:
24mp - more room to crop for what I do
button layout - especially the rear AF button is just perfect
faster AF - not huge but noticeable
more AF points - I always used single point center, focus and recompose on k-5 but on k-3 I find myself using the AF point select and actually using the AF points. Still don't on the k-5IIs
response - k-3 is just more responsive, quicker due to the faster processor
exposure - more reliable on k-3. I always had +1/3 or 2/3 on the k-5IIs but on k-3 I almost always leave it at 0 compensation
focus peaking - not available on k-5 series but a nice feature on k-3 for macro or when using the tripod
low light AF - really scary good, yes k-5IIs is not bad, k-3 is better
YMMV. Is that list worth upgrading? Only you know that. I have both bodies in the bag and the k-5IIs gets little use.
