I might not have done true justice to the SMC Pentax-M 100mm f/2.8 here. I had it mounted on the Pentax MZ-7, an excellent camera by itself, but mismanaged in the manual setting for the lens. This ended up with the camera/lens combo not working at its best, and I went through half of the film roll with that.
The SMC Pentax M 100mm f/2.8 is, however, a delight to use. It is compact, light, sharp, and solidly built, and enjoys an average user rating of 9.6 on PentaxForms.com. The lens has always stayed at the top of the enthusiast's choice.
The all-manual lens is of 5 elements in 5-group construction and comes with 5 aperture blades. Images, as you can see from these shots, are not as contrasty and can be boosted or adjusted with image processing.
At 100mm focal length, the SMC Pentax-M 100mm f/2.8 is a great lens for outdoor portraits and landscapes, and should be equally suited for traveling by its small and compact size. It has also been reported that, when used in the field, the lens has the potential for purple fringing issues in high-contrast situations.
This is the first time I am using the lens, and as I mentioned earlier, mounted on the Pentax MZ-7. Images were shot on an almost expired Kodak Colorplus 200 and were post-processed on Olympus Viewer 3 (OV3).
