'Analog Diary - Taking the AF Sigma Zoom-Gamma 21-35mm F3.5~4.2 for a walk in the park' 

I already had a copy of the Sigma Zoom-Gamma 21-35mm F3.5~4, a 1979 vintage from Sigma in my collection, had a couple of good outing with it, but went on and decided to add AF version of the lens, the AF Sigma Zoom-Gamma 21-35mm F3.5~4.2, to the jumble.

The lens, an AF version of the same, very highly rated by reviewers on the Dyxum forum, was released in 1985. It came with a 77mm. diameter front element, bigger when compared to the 67mm of the prior, and weighs in at 480 grams.

My copy comes with an EOS EF-mount, and the camera I had to test it on was the Canon EOS 700QD (1990).

Aside from the weight of the camera and lens which totals an almost 1.4 kg (with a heavy duty wide shoulder strap attached), which might not take too long for you to feel the weight when it is hanging down your neck, both camera and lens seem to be functioning well. This is despite their age which are about 35 and 29 years old respectively.

As the case with all cameras that I tested, the first instance was always down to the park, an early morning visit this time, with the main emphasis of the test being the zoom range of the lens. Images were shot on Kodak ColorPlus 200, post-processed on Olympus Viewer 3, and print sharpened on Windows Photo.

Your observation is probably as good as mine to the rich color rendition of the landscape. I will have to work harder, however, on getting sharper images with different subject and lighting condition while going through the various pre-set shooting modes or with the shutter-priority option.
