Panasonic Lumix S 20-60mm F3.5-5.6 Review

Sharpness at 60mm

For this test, the Panasonic Lumix S 20-60mm f/3.5-5.6 lens was attached to a Panasonic S1R body, which was in turn mounted to a sturdy tripod. Exposure delay mode was activated and image stabilisation turned off. Tonal and colour variance across the crops are due to change in natural light during the session.

At 60mm, the maximum aperture is f/5.6. Detail is sharp over the entire aperture range, save for f/22 where the effect of diffraction (an overall softness) is seen when really scrutinising a picture. There is a slight softness f/5.6 and f/16, but again you have to strain to see it.

Again, centre sharpness is maintained all the way to the very corners of the picture when a shallow depth of field is not a factor. The sweet spot of the lens at 60mm is still between f/11, but we would have no hesitation to use this lens even at its maximum aperture where there are no lens distortions either.

We have been surprised by just how sharp this lens is. It's not critically sharp in the same way as lenses three times the price, but it is very sharp indeed!
