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.

Carl Zeiss 2.8/25 T* ZF with Canon EF Adapter: First Use in the Field


I tried the Zeiss 2.8/25 T* ZF for the first time in the field yesterday. As I mentioned in another post to this blog some time ago, this is a Nikon mount lens that I purchased for its unique working distance of only several centimeters. This makes wide-agle shots like this one possible. Unlike with fisheye lenses that are typically used for this kind of photography, with the Zeiss 25mm the distortion is not noticeable. Since I have Canon cameras, I use this lens with an adapter. This means, that all controls are manual. Since the aperture also has to be set manually, the image in the viewfinder is dark. To my big surprise, however, the Live View image was lighter, and focusing was much easier.

Herping lens for Pentax

In May this year I have posted a list of close focusing wide-angle lenses that are suitable for herp photography. Here is another lens for this list that I found later:

smc Pentax DA 10-17mm F3.5-4.5 ED (IF) Fisheye

This lens has a KAF bajonett and hence is suitable only for Pentax DSLR. It has not only very nice short focusing distance of only 14 cm over the entire zoom range. In so-called “super macro” mode its working distance can be reduced to only 2.5 cm. This lens also allows precise manual focusing even with autofocus turned on.
