There are such a lot of glorious second hand lenses on the market, some at give-away costs, maybe as a result of they’re not modern, maybe just because they don’t shout out amongst the sheer quantity of prospects. So right here we now have an unsung, comparatively unknown Tokina zoom lens, most likely courting from the early 1980s, in Minolta MD mount. It’s full body, being a film-era optic, it’s guide focus and it’s simply adaptable to the Sony Alpha A7 III physique used for this evaluate. So, attaching it utilizing the Neewer MD-NEX adapter, let’s run it by its paces and see what it could actually do.

Preliminary impressions are good, the lens weighing in at a stable 510g and feeling solidly made.

The big entrance ingredient is surrounded by an ordinary 62mm filter thread, this lens being made earlier than bayonet match lens hoods turned just about customary. Behind this, the massive and properly gripped focusing/zooming ring operates utilizing the one contact trombone system. Rotate to focus and push/pull to zoom. That is the place what might be the foremost disadvantage of the lens is revealed, as a result of for many of the focal size vary the minimal focusing distance is a woeful 2.5m, or 8.2 toes. This makes utilizing our customary take a look at chart inconceivable till we attain about 50mm, as a result of the lens can’t be centered shut sufficient to fill the body with the picture of the chart. At 2.5m, a 28mm lens just isn’t very helpful except we’re capturing at a distance.

Nevertheless, at 105mm the lens will be centered nearer into an space marked as “macro” which permits us to maneuver in to 0.9m, or three toes, a most magnification of 1:6.6. That is hardly near macro, however no less than higher than the usual vary. Additionally it is extra acceptable to have the macro vary on the longest focal size, permitting area for lighting the topic. It’s not a flat area although, so though we transfer nearer this isn’t the lens for copying paperwork and different flat topics.

A one contact zoom does although have one benefit, and that’s the capacity to have a significant depth of area indication that reveals traces for f/5.6, f/11 and f/22. The f/5.6 line additionally reveals the Infra Crimson correction and is marked in purple. A small white index mark signifies the change in aperture worth when zooming from 28mm to 105mm.

Lastly, the aperture ring is nearest to the mount and operates properly sufficient, though it’s not as easy and refined as we now have change into used to on many trendy lenses. The Neewer adapter is solely a hyperlink and there are not any electronics connecting lens and digicam, nor are there any cease down linkages.

The consequence is that no matter we set on the aperture ring is what we now have and the picture will darken as we cease down. The method used will most likely be to focus broad open after which simply rely down the clicks to set the aperture desired earlier than the shutter launch is pressed. This works simply sufficient.

There have been varied mount choices accessible, together with Contax/Yashica, Canon FD and FDn, Minolta SR (MD, MC), Pentax PK-A, Nikon F and maybe others as properly. Adapters are comparatively cheap and available.

Optical development is 15 parts in 14 teams. The lens is multi-coated and has six diaphragm blades. The SD designation within the title signifies the usage of Tremendous Low Dispersion glass.

Dealing with is easy sufficient, though guide focusing just isn’t significantly exact because the focusing throw may be very brief. Nevertheless, utilizing varied in-camera focusing aids does assist accuracy, while slowing the image taking course of down. The largest bugbear just isn’t having the ability to method shut sufficient to make wider focal lengths any use. This is able to be an issue with close-in avenue images, however, to be truthful, not a lot with panorama capturing. Having a separate “macro” vary is one thing that may be very a lot of the lens’s period and never wherever close to as handy as a steady focusing vary.
