Hi all, I'm very lazy. So, on Friday, after taking pictures around the yard to test the Sigma 400mm f5.6 APO for flare and general performance; as well as the feasibility of using the P30t at -27C, I simply processed the film in the same old stuff I've been using since the first week of August. The results were no different, to my eyes, from those obtained during the first processing. This was the 15th film done in the same 500 ml of solution that is supposed to do only 8 _as long as you do two films at a time_. I do them one at a time. So, conclusion number one from this test is that the P30t works fine at 27C degrees below zero and two is that Tetenal engineers have been rather conservative in their recommendations. I swear I'm going to mix up more chemicals soon! Incidentally, I was outside for about half an hour, time enough for the P30 to get quite cold. Maybe the plastic helps?
I tested not only the Sigma tele lens, but also the Takumar A 28~80 Zoom Macro f3.5~4.5 for flare, shooting right into the sun with the zoom and almost directly with the telephoto. I also took a few shots with the Sigma 50mm f2.8 macro and the SMC-M 50mm f1.7. I've posted the results on my website. If anyone is interested there is a link below. All the images shown are from films that have been processed in the same chemicals - now four months old. I've included one directly scanned image of the end of a film trimmed so that it will go perfectly into Nikkor S/S processing reels, or any S/S reel for that matter. I've mentioned this trimming before. The tele shots were all taken at f5.6 and either 1/500 or 1/250. The films were Ferrania Solaris and Kodacolor, both ISO 200. Naturally a big solid tripod was used for the long lens shots. The others were hand held. I used the big Metz flash and a Vivitar 135mm f3.5 tele on the P30t for the little bird - no tripod. There is interesting OFE in two of the pictures. http://personal.inet.fi/cool/don.williams/hold/index.htm Don Dr E D F Williams http://personal.inet.fi/cool/don.williams Author's Web Site and Photo Gallery Updated: March 30, 2002
