Comparing an assortment of CONTAX Zeiss lenses at minimum focus distance

For this test I wanted to see how my current collection of CONTAX Zeiss lenses compared at minimum focus distance. This will give you a sense of the focal lengths, lens compression, bokeh, and other characteristics while choosing a CONTAX Zeiss lens. No images have been corrected or modified in any way.

For this test I have sheepy in front of a miniature Christmas tree. He never moved for the test.

First up is the 28mm f2.8

Followed by the 50mm f1.4

Followed by the 28-85mm f3.3-4

Followed by the 135mm f2.8

Followed by the 80-200mm f4

Followed by the 180mm f2.8

Followed by the 300mm f4

CONTAX Zeiss 300mm f4 @ MFD & f4.

What conclusions can I make from this?

For starters, the 50mm f1.4 seems to give a very pleasing rendering, which is able to capture enough of the sheep, while also melting away the background. The zoomable 28-85mm f3.3-4 has a fairly poor minimum focus distance at 28mm, meaning I couldn’t isolate the sheep, and ended up getting much of the couch in the photo; however, it does a more pleasing job at 85mm.

Surprisingly, the 80-200mm f4 can get closer at 80mm than it can at 200mm, and our winner in the tight crop department has to be the 180mm f2.8, I could only get the head in the frame at MFD. The 300mm f4 has the most compression, no surprise there, but it’s not able to blur the backgrounds like the 180mm f2.8 or the 50mm f1.4.

Let me know your thoughts below!

CONTAX Zeiss 50mm f1.4 vs Nikon 55mm f1.2

This is a quick comparison showing the minimum focus distance of the CONTAX Zeiss 50mm f1.2 to Nikon’s 55mm f1.2. The vintage 55mm from Nikon has been my go-to “Nifty 50” for quite some time. I’d really like to see how it stacks up against the 50mm from CONTAX.

Minimum Focus Distance of CONTAX 50mm f1.4

I’m really impressed with the close focus distance of the CONTAX lens. Here it is at MFD wide open at f1.4:

CONTAX Zeiss 50mm f1.4 @f1.4 and minimum focus distance.

Minimum Focus Distance of Nikon 55mm f1.2

I’m really impressed with the CONTAX 50mm f1.4. I would have assumed that my Nikkor lens had a better ability of blurring the backgrounds as an f1.2 lens, but the ability of the CONTAX lens to get closer to the subject actually gives it more background blur. Here are the two images side-by-side:

Nikon 55mm f1.2
CONTAX Zeiss 50mm f1.4

The Nikkor lens appears warmer in this example but that’s not typical from what I’ve seen. It may just be the light through the window changing.
