I still translate in my head when I'm using APS-C. It definitely takes experience to be equally comfortable in both formats. The catch, of course, is for those of us who use both systems. Then you won't need to worry about the translation. Learn what subjects work well with the field of view of a 35mm lens on APS-C. Learn what f-stop will give you the depth of field you want. It's still a 35mm f/1.4, so just learn how a 35mm f/1.4 behaves on an APS-C camera. A 35mm f/1.4 lens doesn't change physically because you use a smaller sensor. However, the best scenario is actually just to get comfortable enough with lenses on an APS-C format camera that you can think in those terms without having to translate into full frame equivalents. It's an accurate translation, because the 35mm f/1.4 will behave on your APS-C just like a 50mm f/2 behaves on your full-frame camera. You put a 35mm f/1.4 lens onto your APS-C lens and you "translate" it into 50mm f/2 (approximately). When you are first learning another language, you tend to hear words in the foreign language then translate them in your head to your native language. I always think about this the same way I think about learning a foreign language. Worry about what a camera can do and not what it can't. All that matters is that smaller aperture numbers gives smaller DoF. So if you shoot a M with a 50mm lens set at f2 and a TL with a 35mm set at 1.4 the resulting images will look similar (technically it would be 52.5mm and an aperture of 2.1).īut honestly it's a daft thing to get hung up on unless you really know your stuff. Multiply the focal length and the aperture numbers by 1.5. So if you are shooting on a TL with a 35mm lens at f1.4 and you want to know what 35mm format lens/aperture will give a similar looking images you use the "crop" factor. And because the amount of enlargement required to make an equivalent print size the "apparent" DoF will be increased. Because the TL sensor is smaller the angle of view is reduced. They will act the SAME in respect of exposure. M35 Summilux = TL 35mm Summilux when used on a TL.īecause the M and TL have a different sensor size a 35mm 1.4 used on each camera will behave differently in respect to angle of view and apparent DoF. It only matters what size sensor it is used on. It does NOT matter that the M lens is made for a larger sensor. 1.4 the way it behaves will be the same as the TL 35mm 1.4 on the same camera. So if you take a TL camera and fit an M 35. A summicron is a summicron is a summicron. F2 is f2 regardless of camera, sensor size etc etc etc. It's the relationship between the focal length of a lens and the diameter of the aperture opening. When used on my leica TL?Īperture is aperture. So, according to the calculation, my Leica M 35 f2 has an aperture of 2.8 and my Leica TL 35 f 1.4 has aperture of 2.1. That's to say I'm very happy with my new TL2 and TL 35 summilux. So is an apsc summilux really a summichrom? Because when it comes to full frame, what about my leica TL 35 f 1.4, is it actually a "leica tl 35 f 2.1? ![]()
