Tamron 28-75 makes a case

To be the lens that stays on the K-3 most of the time:

The K-3 seems to like 63mm (95mmFF) with this lens.  This lens was just rated above average on the K-5 and my records show a -2 fine AF correction.  No AF correction needed with the K-3 and this lens:

63mm 50% crop

100% crop from above

another 100% crop

63mm f/5

It likes 75mm also watch out 70mm ltd at only 1/3 stop faster and Tammy is 30cm min FD as opposed to the 70's 60cm

50mm not bad either.

So do I need the 70ltd if I have the Tammy on a K-3 ?

50mm Tamron 28-75 at f/5 ambient side lit through near window on K-3 50% crop
