Outstanding in every respect.

The mechanical aspects of the Panasonic 12-35mm f/2.8 12-35mm zoom were outlined here.

This is a costly zoom and for the money you get a fixed f/2.8 maximum aperture, a far higher standard of construction than the kit zoom, with silky smooth controls, and bulk not much greater than the kit lens. The original 14-45mm kit zoom was a fine optic and you can read about it here. It has long been discontinued but affordable ones can be found on the used market.

What does the 12-35mm add? Outstanding micro-contrast and edge to edge sharpness even at full aperture, an f/2.8 which comes in handy in marginal lighting. And the extra width at 12mm is a good trade-off for the loss of 10mm at the long end.

Here’s a selection of images taken in Williams and Sedona, Arizona the other day.

Except for modest use of the Highlight and Shadow sliders in Lightroom for the Williams images – the late sun lighting means very high contrast – these are pretty much straight out of camera, my Panasonic GX7.

Proof of the pudding? The Panny 12-35mm has replaced three of my other MFT lenses – the 14-45mm kit zoom, the Olympus 17mm prime and its brother the Oly 45mm prime. All sold. Now my MFT kit is back to basics, consonant with the ‘small and light’ concept of the original design. I own only one other MFT optic, the excellent 45-200mm zoom, with its mighty reach for special occasions. It resides permanently on my other GX7 body.

Here’s the ‘contact sheet’ from the Williams outing; having grown up poor and using film, digital waste is not something I indulge in:

The two images with a ‘2’ in the upper left corner were roundtripped via Photoshop – the first to remove overhead wires, the second to fix verticals.
