Results of 150mm Apo-Sironar N Lens for Copy Work (Versus Tominon)
Hi,
Ok, i took trannies at f16, f22, and f32 (11 sec). And with the Apo-Sironar N, the f32 looked the sharpest. The brochure said f16-22 would be the sharpest, so i don't know if this one pic was a fluke. But it's surprising considering the risk of camera shake at such a long exposure time. Even at f22, the Apo-Sironar was a tiny bit sharper than the Tominon 127mm. But it really is a bit hard to tell, even with my 10x loupe...perhaps the difference will be more noticable when i scan it, but the Tominon is pretty close. Interesting Note: The Schneider Xenar was STILL sharper in the center of the field! I will definitely keep the Xenar for 6x6 film work. I will use the Apo-Sironar trannies, as they are the most sharp and even overall. BUT, would it really be worth spending $450-550 for a used Apo-Sironar, versus the $40-60 of a Tominon? I dunno if it's really worth it, to tell the truth! The other one i was considering was a Rodenstock 127mm, f4.7-45, in a prontor i believe? I local repair shop wants $195 for it... Slick |

That's the same lens as the tominon, if it's a ysaron, except it's made by rodenstock. I've only used the 105mm version on 6X9 but it's a nice close up lens as well. And you're right I don't think an APO-sironar-n is worth the price difference. For $60 the tominon is hard to beat. -- Stacey |

The Apo Sironar N is corrected for working ranges from 1:10 to infinity. It was not made to be a copy lens. For superior copying results you will need either the Apo Ronar at f22 or an Apo Macro Sironar at 1:5 to 5:1. The Apo Ronar's smallest focal length is 240mm, which might be a bit too long for my Crown Graphic? In terms of bellows draw? S. |

The shortest Apo Ronar was a 150 which may cover depending on your magnification range. I didn't see this one in the brochure, and i couldn't find one this short on Ebay. Perhaps they don't make them anymore? |
