Nevertheless, the image rendering and bokeh difference is much less than expected if the distances to the object and background are increased compared to a full-frame camera.īoth classic Biotar type lenses proved able to deliver good images, with a beautiful image rendering character and bokeh when adapted to the Sony a7ii full-frame and a6100 APS-C cameras. The image rendering and bokeh of these lenses are different, depending on whether they are adapted to a Sony a7ii full-frame camera or to a Sony a6100 APS-C camera (the sensor size of an APS-C camera is only 2/3 of a full-frame sensor). The image quality and bokeh of the Carl Zeiss Biotar 58mm and Helios 44M-4 58mm classic lenses barely differ. the Russian copy Helios 44M-4 58mm f2 lens Swirly Bokeh? The legendary Carl Zeiss Jena Biotar 58mm f2 vs. Read more about the origin and history of the Carl Zeiss Biotar and Helios 44M-44 58mm f2 classic lenses here These photos demonstrate that the Russian Helios 44M-4 58mm f2 lens for EUR 60 delivers the same image quality and bokeh as the Carl Zeiss Biotar 58mm f2 lens for EUR 250, and both lenses performed well when shooting them on a Sony a6100 camera with a smaller APS-C sensor. These were on show at a former Echelon and NSA satellite tracking station compound in Bad Aibling, southern Bavaria, on the 31st of July, 2021. Let’s have a look at some photographs of classic cars. Slideshow | Fullscreen | Image-Info | Original-size Comparison: Photos of Carl Zeiss Biotar and Helios-44 58mm f2 lenses adapted to a Sony a7ii full-frame camera and a Sony a6100 APS-C camera When you click on an image in the galleries, following buttons will allow you to select some features, including a slideshow (which is auto-started for some galleries, you have to press the pause button to stop a slideshow): The good thing using those Biotar type lenses with an APS-C sensor is, that the lower performing corners of the lens are not used, but otherwise the sensor pixel density is higher. That makes the field of view almost the same as a 85mm portrait lens used on a 35mm equivalent full-frame camera like the Sony a7ii. When German and Russian Biotar type 58mm lenses are used on a Sony a6100 camera with an APS-C sensor, a crop-factor of 1.5 applies. In my opinion, the following photos quite nicely answer the following question: Are the German Carl Zeiss Biotar and Russian Helios-44 58mm f2 lenses of any use when adapted to full-frame and APS-C digital camera bodies? How does the Carl Zeiss Biotar 58mm f2 lens made in 1953 and its Russian copy Helios 44M-4 made in 1990 perform when adapted to a Sony a7ii camera with full-frame sensor and especially a Sony a6100 camera with a smaller APS-C sensor?
