A subjective look at Cosina AF 19-35mm F/3.5-4.5 MC @ Canon EOS 5D. Part 4 — Optical Results

For the purpose of this review Cosina AF 19-35mm F/3.5-4.5 MC lens was used on Canon EOS 5D DSLR.

Canon EOS 5D is now discontinued amateur fullframe digital SLR camera announced back in 2005. The camera is equipped with Canon 12.8 MP CMOS sensor. The Low-Light ISO parameter of the sensor measured by DxO Labs is 1368. Auto ISO function is only available in fully automatic green mode and is restricted to the range of 100-400. The camera produces 12 bit RAW images and is only compatible with Compact Flash memory cards. There’s no Live View mode and no built-in flash.

However it was quite comfortable to shoot with this camera due to really large and bright optical viewfinder common to all fullframe SLR cameras in general and Canon 5D in particular.

The images which illustrate this review were developed in Adobe Photoshop Lightroom 5.6 WITHOUT correction of distortion, vignetting and lateral chromatic aberrations, WITHOUT sharpening and increasing of overall contrast, brightness, saturation and WITHOUT changing of any other settings.

With a wide angle of view provided by the lens on a full frame camera, it is possible to make pictures with impressive perspective. Visually the lens is sharp in the center of the frame at all focal lengths already wide open. The sharpness increases with closing of the aperture and remains excellent with Canon 5D even at F/14-16. The edges of full frame are different story though. Wide open the edges are mediocre at all focal lengths (while the corners are even soft), but their sharpness increases gradually with closing of the aperture and becomes more or less good, I think, from F/8.
