Carl Zeiss 2.8/25 T* ZF on Canon as Herping Lens


Today I tried out the Carl Zeiss 2.8/25 T* ZF with a subject that I actually planned this lens to use for. Above you see my first herp photo with this lens – a Common Frog (Rana temporaria). I had no flash with me this time, and was shooting with high ISO – 1600. Nevertheless the shutter speed was quite slow – 0.8 sec – due to narrow aperture – f/22. Even with this aperture which is maximum for this lens the background blur is quite strong when the subject is so small and so close. The frog was only about 5 cm from the front of the lens.

To eliminate overexposure in the top of the frame, I am using this lens with a B&W gradient filter.

The image presented here is a full frame, and with normal processing – gradation curve, saturation and vibrance increase, sharpening.

Bottom line: This view angle is not as wide as in fisheye lenses, and with small subjects the background is too much blurred even at maximum aperture. Shooting with f/22 is very difficult because the image in viewfinder is almost black. On positive side, the distortion is virtually absent. The lens provides typical for Zeiss nice realistic colour rendering and contrast.
