The Pentax 35mm f/2.4 SMC DA AL features a maximum aperture of f/2.4. Coupled to a Pentax APS-C D-SLR such as the K-r, K-5 or K-7 it offers a film-equivalent focal length of 52.5mm with the 1.5x crop factor, and features a construction of six glass elements in five lens groups. It has a six-blade aperture design but unfortunately has a plastic mount at the rear that’s susceptible to more wear and tear than a metal one.
Being so light in weight, it feels a little basic and with the AF/MF control taken from the body on Pentax D-SLRs there’s no focusing switch to be found on the barrel.
The finely grooved focus ring is smooth and it’s extremely well weighted for subtle focusing adjustments. The front element isn’t fixed and protrudes by 10mm when the lens focuses on close subjects. The 30cm minimum focusing distance is on a par with most other primes and although some loud whirring was evident when focusing, it managed to lock onto subjects very quickly with no obvious signs of hunting.
For those who like to use filters or adapters on their lens, it has a 49mm thread at the front and although the front element extends, it doesn’t rotate so is fine when using graduated filters or polarisers.
