Pentax, Sigma and Leitz 500mm..560mm optics

Well, now the Pentax 560mm is priced beyond reality, some may find an older test of my museum pieces interesting.


The heavyweights :


Takumar 1:5 500mm (from around 1960)

Leitz telyt 1:5.6 560mm (before 1970?)

SMC Pentax 1:4.5 500mm (optical design form the sixties, the K version dates from the seventies)

Sigma mirror ultra telephoto 1:4 f=500mm (early seventies)

The test target :



And the rest are 100% Pentax K5 crops.

Sigma 500 at F 1:4:


Leitz telyt 560 at F 1:5.6:


SMC Pentax 500 at F1:4.5:


Takumar 500 at F 1:5:


Unfortunately, the lighting changed a bit during the test, but it takes time to swap these lenses, and the weather is beyond my control.


Conclusion :
Sharp to less sharp : SMCP, Leitz, Takumar, Sigma
Highest contrast to lowest contrast: Leitz, SMCP, Takumar, Sigma
Most 'colorful' to least purple fringing: SMCP, Takumar, Leitz, Sigma
Easiest to carry around : Sigma, Leitz (in parts), SMCP en Takumar.
The worst tripod connection : with a big margin, the sigma 500

Handheld usable : only the Leitz.

I want all tele lenses to have the same pistol grip accessory as the Leitz. That's amazing looking.

Interesting review, it's the kind of review I like, no nonsense, what does look it like on the image.

So now all the rest will be sold then, to fund other LBA.

Thats possible, one of the two grips is from Fuji, I assume for some videocamera:


I removed the internal electronics:


And adapted it for triggering a pentax DSLR.
