About the Voigtländer Nokton 40mm f1.2 aspherical I know nothing but that it probably is a „Distagon“-type lens as my Batis is … There is as far as I know also a modern Voigtländer lens 40mm f2.0, which I never tried! As it is an „Ultron“-design (and also includes an aspherical lens) it should also be of top notch performance. As far as I know, Canon never played around with something like that … nor did Leica! What a pitty! The Pentax DA 45mm f2.8 Limited is famous (a Gaussian!). I once owned a Nikkor 45mm f2.8 pancake-lens of 1977 on the Nikon F3M – it was a just average Tessar design. There are other famous historical lenses, which are not available to me: … and there is an interval of 65 years in making betweeen all of these lenses! Sigma 40mm f1.4 for Sony-E-Mount (FullFormat) of 2018įujinon 50mm f3.5 for Fujifilm GFX50/100 with sensor 44mm x 33mmįrom this list of 11 lenses you can make the conclusion how important this focal length is to me! Panasonic 20mm f1.7 for Micro Fourthirds (corresponds to 40mm at FullFormat)īatis (Distagon) 40mm f2.0 for Sony E-Mount (FullFormat) of 2018 … and the modern available to-date lenses:įujinon 27mm f2.8 pancake design for APS-format X-trans sensors (correspond. Planar 45mm f2.0 for Contax G1/G2 of 1994 Olympus 40mm f2.0 – an ultra compact pancake design of 1978 for OM cameras Minolta M-Rokkor 40mm f2.0 with Leica-M bayonet (for the 1973 „CL“ Leica/Minolta) MD-Rokkor 45mm f2.0 – a pancace-type standard lens for Minolta SRT cameras of 1978 „New“ Tessar 45mm f2.8 for Contax/Yashica-Mount – a 1983 design based on new glass Tessar 45mm f2.8 as fixed lens in the Contaflex II of 1953 In fact this focal length was ALWAYS present in the photo industry for system cameras – and I own some of them: In early times most of the point-and-shoot-cameras with fixed (built-in) normal lenses had 38mm to 45mm lenses … and there are still some today. This history may have strongly influenced me in my preference for this focal length – but you may also find one thousand good reasons for this focal length, which is the „real normal focal length = the diagonal of the 24 x 36-format“ indeed: longer than 35mm, shorter than 50mm. It was the time before the German photo industry „suddenly“ collapsed and when the local camera dealer still could repair a Contaflex II mechanically just within a day! (And there was nothing else really but mechanics – you will not seriously call a Selen photosensitive cell „electronics“?!) The first camera, which very early „socialized“ me for Single Lens Reflex Cameras was the Contaflex II with Tessar 45mm f2.8 of 1953. … and it is the perfect focal length for street photography – and it may be the best, which can happen to you for all situations in which you have just one focal legth to choose, which means: you have no choice really …
