MINOLTA G-ROKKOR 3.5/28 Photo example / HEXAR-RF
Impression
A compact 28mm wide-angle lens with a beautiful silver barrel.
The GR28mm released in the same era weighs a hefty 180g, but this one is made of aluminum and is much lighter at 110g.
I used this lens often with film cameras, and as you can see in the photo below, it looks very good when attached to the ZEISS IKON and MINOLTA CLE, and it gives you an exciting image that stirs your photographic desire. When used with a film camera, if you are conscious of vignetting, you will hardly notice any drawbacks. Although neither of these systems is already in my possession, I think I can grin just by having them.
When used with the LEICA M9 digital camera with a 35mm full-size sensor, vignetting and color blurring were sometimes a concern, but with the α7s and other recent sensors, color blurring is not a concern.
This lens has no lamination surface, so there is no need to worry about balsam loss, which is a welcome feature for an old lens. The Ricoh GR 28mm (the same goes for the wider 21mm), which has the same angle of view, has a fairly high probability of being fogged up.
It was released in 1998, but new ones were available at camera shops until around 2005. It was an idyllic time when even limited editions did not sell out so quickly, a time different from today’s too-busy world.


Specification
The lens used in the high-end TC-1 compact camera was released in a limited edition of 2,000 in the Leica screw L mount with the same lens configuration as the TC-1.
The TC-1, the compact camera on which this lens was based, had an interchangeable circular plate for the diaphragm blades, but this L-mount version has an aperture with nine blades, which is more convenient for normal use.
It comes in a luxurious package with a nameplate, and the cap at the end of the hood is made of the same material as the lens and is screwed on with the MINOLTA logo.
This is MINOLTA’s first lens for the Leica L/M mount in a long time, since the release of the M-mount lens for the Leitz Minolta CL / Minolta CLE.
