I have a 28 Elmarit, but don't think it will be wide enough. >By the way, between the 21mm's, does the Elmarit have more distortion than >the Super Angulon? I don't have any Heliar pictures on my site yet. Anyways, it wouldn't help you much, as anything less than a high-end drum scan would obscure the results, and such scans I only get done for well-paying clients. The 15 Heliar is fully up to the standard of the old 21 Elmarit, if not up to the 21ASPH. The 15 Heliar's performance is on a level with the 3rd version of the 28 Elmarit, but not quite that of the 4th (current). All these lenses have more distortion than the SA, but none have any amount that can be called significant. All are better than any SLR lenses in this range I know of. If you need 110 degree coverage, and high quality, why not go MF? A Horseman 612 with shift and the 35 Apo-Grandagon will give you either 6x12 or 6x7 with shifts, which are likely to be more useful than a 15 on 35. A swing lens panoramic like the Noblex will give you nearly 130 degree horixontal coverage, with less _perceived_ distortion (in some respects) than a 120 degree rectilinear image. In any case, the 15 Heliar is the best game in town for 35mm work at this time, unless you can get away with 90 degree coverage, in which case a lot of other options open up. * Henning J.
