Tim Rudman, Spring Lith News

Tim Rudman, a well-known promoter and practitioner of lith printing techniques, has a number of projects in the pipeline for this summer. First, is his self-printed photo book of Iceland, done in conjunction with American photographic artist, Bill Schwab. Tim setup his own printing company to meet his exacting standards and requirements, Opas Books. The book is 'Iceland, an Uneasy Calm' and will be printed in hardcover and bound by cloth in Verona, Italy. The plan is for an initial run of 1,000 books with a limited run of deluxe copies housed in a silk or cloth clamshell case. The book will contain at least a 100 plates.

Tim also mentions that Foma has shipped to him several samples of updated printing material with updated technical notes for lith printers. He will be reporting on his results with these papers later in the summer.

Wolfgang Moersch, a powerhouse of darkroom chemistry, has also sent Tim a sample of a new product 'Lith G' for the enhancement and control of image colour. Tests of this product are also forthcoming.

Review of the Sigma 24mm f/1.4 Art lens

Roger Cicala of LensRentals compared and contrasted the new Sigma 24mm Art series lens with Nikon and Canon 24mm lenses along with a comparison to the Rokinon 24mm. While the Sigma may be as good as, if not marginally better than the Nikon or Canon lenses on the optical test bench, Roger concludes that "the old rule that the best 24mm f/1.4 is a 35mm f/1.4 and a few steps backwards is often true." The article has detailed MTF charts for all the lenses mentioned and pinhole test images of the Sigma.

The conclusion from all the testing is that the Sigma, Nikon and Canon lenses are all pretty sharp at the center, but focus and constrast fall off quickly towards the edges. The exception was the Rokinon, which had a fairly flat response to the edges, but was not as sharp and contrasty at the center. Roger says that in the "outer 1/4 of the image it [the Rokinon] is as good as the Sigma, or perhaps a bit better." Depending on price and what you want, the Sigma is a strong cnotender against the Nikon and Canon lenses, and the Rokinon may be more consistent overall and just as good off-center as the others.

If you are looking for newer designed lenses for your kit, Roger declares the Sigma 35mm f/1.4 lens to be the best 35mm wide. Being full-frame lenses, these lenses should work with compatible film cameras. To keep costs down, keep in mind eBay and the B&H Used Department.
