|Sigma Aspherical 24-70mm f/3.5-5.6 D (1994)|
Sigma launched their super compact zoom lens in 1994, the Sigma 24-70mm f/3.5-5.6. It incorporated aspherical elements to control aberrations and distortion.
I have only borrowed this lens and what I can share here is merely first impressions. The copy that I had, was unfortunately suffering from severe flare problems, hazy images and lack of contrast because of one hazy glass inside. It would be fair for me to inform you about this, before you conclude based on my test samples.
There does not seem to be much of a big difference from a later version of this lens that Sigma launched in 1996, the Sigma Aspherical 28-80mm f/3.5-5.6 D Macro.
Same appearance, size and weight. The mechanisms also appear to be the same. They are both close focusing at 0.5 meters.
The only difference I saw was that the later 1996 version can get as close as 0.2 meters (1:2) at 80mm, but having to turn on the Macro Mode switch was really an annoying ritual!
