Its been a while since we've been out with just one zoom lens. The last time was with the Panasonic 14-140mm. Carrying it round for the day, it did start to feel quite bulky. However to get some idea the combined weight is approximately the same as a Canon 5D Mk II body only.
Due to the general sluggishness of the Olympus E-P2 AF and the added slowness of using a 4/3 to m4/3 adapter focusing was occasionally a bit slow, though for landscape/location work perfectly adequate.
The results were as good as we expected. Sharp, good colour, virtually no CA.
