I am sure the bellows is not quite as convenient as a macro lens. I have the Novoflex automatic bellows, but, of course, the 100/4 is a one cam, stop down metering affair. I have contacted Leica about adding extra cams and they say that lens cannot be upgraded like the other one/two cam lenses. So, I have to use the DOF preview lever while metering. I have toyed with the idea of disconnecting the auto levers in the bellows so the lens will stop down w/o having to depress the DOF lever. I often forget get improperly exposed photos. Or if the light changes it takes more time to adjust the exposures and I might miss my opportunity. Can't use one of the auto exposure modes. So, here are my choices. I could get the 100/4 macro at a reasonable price or the 100/2.8 APO at about 3x the price. I have been happy with the quality of my bellows 100/4. Is the focusing macro 100/4 the same optical formula? I am sure the 100/2.8 APO is a very fine lens, but is it worth the difference for 1 f-stop? Does it perform that much better at f 5.6 and beyond? For most macro work, DOF is at a premium, so stopping down is mostly the rule, not the exception. Both of these lenses need "help" to reach 1:1 and beyond. If I save my bellows, they could both work in auto mode on the Novoflex bellows. Would the 100/2.8 APO perform well at 1:1 using extension rather than the special optics designed for 1:1? I also have a 90/2.8 that I use. If I bought the 100/2.8 APO, would that make my 90 expendiable? Would the 100 perform as well for portraits? For infinity shots? Is it bulkier than the 90/2.8? Any help would be appreciated. Thanks Aram This message is made of 100% recycled electrons. No new atoms were destroyed in making it. Aram Langhans Science Teacher, Naches High School P. O.
