What Are Your Experiences with 28mm Lenses?

I'm interested in getting an inexpensive 28mm lens for the KP, as I think that gets me closest to 40mm equivalent, which is a focal length I really like. I like small primes, but I'm willing to experiment with anything if it's inexpensive. Do you have experience with a 28mm that you like, and why?

Manual focus or AF?

Either one! I know I'll have to pay more for AF, but I'm still interested in hearing about them.

For me AF only in zooms, primes I have 5 or 6. Favourite is an M42 version vivitar 28/2.5 with 67 mm filter., but note, I also have sigma super wide 2 in ka mount that suffers really bad lateral CA, a tamron . Adaptall 28/2.5, a vivitar 28/2.5 in K mount with 62 mm filter, a Kiron 28/2 in k mount ( note these lenses are subject to sticky aperture blades

the only 28 I ever enjoyed using was a Sigma 28/1.8 EX DG...

I have the A28/2.8. I don't use it much because I find it hard to nail the focus. It would not be my choice for a walk around lens, but that may as much be due to user limitations as anything inherent to the lens. It has a fairly narrow focus throw which also makes it challenging.

The f and fa 28 arenít bad. Thereís debate about which is better. The fa is a new design comparatively. It has an aspheric lens, the f design is based on the old A series design. Iíve owned that A28 f2.8 lens long ago, and I thought it was good.

FA 28 mm f/2.8 AL.

This is one of the best lenses I have, be it on the K1 (2 wide-angle upper pictures) or on the K3 (three lower pictures as a short normal).

I don't own a 28mm prime, but the FL is useful on FF. The short end of my DFA 28-105 gets quite a workout.

Ironically the only 28mm autofocus prime Iíve ever owned is the Sony FE 28 f2.

Ok...here is a short list of considerations:
  • Being a component of the classic three lens kit (28mm, 50, 135mm), there are a ton of them out there from all of the major makers as well as a plethora of 3rd-party and house-branded examples
  • Most are acceptably good and many are very good, optically; few are exceptional.
  • Very few feature or need exotic optical designs and most are f/2.8 maximum aperture though f/2.0 and f/3.5 are also represented.
  • At least one has cult status (Pentax-K 28/2.0 "Hollywood") and a few others are considered more desirable; the Vivitar 28/2.0 MC Close Focus (Komine-made), Vivitar 28/2.8 MC Close Focus Wide Angle (Komine-made), XR Rikenon 28/2.8, and Pentax-K 28/3.5 come to mind.
  • Field curvature is a common, though not universal, fault.
  • With possible exceptions of the f/2.0 models, most should not command a premium price.
I own four in Pentax-K or M42 and have no difficulty recommending the Tamron 28/2.5 (02B) or Vivitar 28/2.8 Close Focus (Komine-made).* Both the Tammy and the Viv feature close-focus and the Tammy was designed as a flat-field lens.


Tamron 28/2.5 (02B) on Rollei Retro 100 with Ricoh XR-2s




Tamron 28/2.5 (02B) on Fujichrome with Ricoh XR7




Vivitar 28/2.8 MC Close Focus Wide Angle (Komine, Palmar K02) with K10D




Good luck!


Steve

* The other two are an S-M-C Takumar 28/3.5 and a Vivitar 28/2.5 (Kino Precision, Palmar M13). The SMC Tak is an excellent lens, but slow and the Viv is decent, but big and heavy.

I own the F 28mm and it is decent even out to the corners on my K1. It is better than any of my zooms at that length. That being said 28mm is not a focal length I shoot very often on FF or APSC so it doesn't see a lot of use. I much prefer 35mm as my wide on FF or normal on APSC.

I've also got the Vivitar 28/2.8 MC Close Focus Wide Angle (Komine-made), it is a great lens, not quite up to modern standards, but very close. The close focus is something I use all the time. They usually are priced around $50, much cheaper than the f2.0

I've got a really low-end 28mm f2.8 from the brand "Formula 5" that has terrible bokeh, not overly sharp, and for some reason I've always liked it.
