I haven't posted here for quite some time now, although I have always kept current by regularly browsing. So, it's nice to be back. Like some, I became more involved in the digital end of things, once the output quality became more viable. At the moment I'm very interested in alternative process printing, using both trad. & digital negatives for source material.
For some time now, I've wanted to do some lens comparisons, between older vs newer glass, esp. looking at what difference the presence of coatings makes (or not). The lenses sampled here include the following:
1. G-Claron 355mm SC
2. G-Claron 270mm MC*
3. Docter Germinar f/9 240mmW MC
4. SK Tele-Arton 240mm f/5.6 SC
* That's not a typo. This lens is in fact multi-coated, which of course isn't how they were produced. I've had this lens for years, but for some reason, never got around to using it. The results for the 270 G-Claron appear clearly to be on par with the Germinar which does have modern MC from the factory. Please excuse the forgettable compositions, and down and dirty scans. I was out shooting with my friend, and wanted to quickly take advantage of the sun that came out, to utilise some potential for lens flare. All lenses, except the 355mm G-Claron, had lens hoods on, with about 3/4 sunlight across their fronts. So, the 355 G-Claron clearly suffered the most from flare. The Tele-Arton shows lower contrast, which is to be expected for a SC lens, but doesn't seem to suffer too much from flare.
I've got a couple older lenses, in barrels, that I'm going to try next: a Ross 14.5"/8.5" Combinable uncoated, and a Cooke 8.5" process lens SC.
Any thoughts? I'd like to hear what others think.
