Hi,
Has anyone been using Tamron 90mm Macro on K-5 and found that it has problems finding focus? I was just checking today all my lenses on K-5 to see, if any of them need AF adjustment, just to find that K-5 realy doesn't like my macro lens.
The focusing is just erratic.
So I thought the focusing would be OK as long as I wasn't trying to focus on objects that are difficult to lock onto ( low contrast objects, objects in the back/foreground ). In almost every case the camera is just focusing back and forth several times and stopping without locking focus on anything. Tried to focus on some simple to focus objects, but K-5 just refuses to find focus. Trying again and again, but focus only locked on the object a couple of times.
So I tried this lens on my old K10D and focusing works much better, not locking focus only a couple of times. And even if it didn't find focus after the first try it locked focus after I pressed the af/shutter button again.
Is it possible that K-5 has problems with this lens, or is the lens?
