RE: Popular Photography 31/1.8 Limited test (WAS: Re: Pentax a "best ever prime lens" at Pop?)
Popular Photography changed the SQF system recently and scores from past tests are not comparable with the new system - I don't remember when the 35 f2 was tested, but I think that the scores from it and the 31 LTD are on two different scales. The new system was meant to be more stringent. - MCC At 05:20 PM 2/17/02 -0500, you wrote: >OK, I looked it up.

The MTF numbers are quite high (but, since Pop Photo just changed their testing equipment, current numbers are said to be 5-7% lower). It is slightly weak at f2.0 and 2.8, but that seems to be the main difference from the 31 in terms of sharpness. And even at those apertures, sharpness is probably adequate for moderate enlargements. My right brain is trying to convince my left brain that I can do just fine with the 35. So far the left brain is holding its own. Joe - This message is from the Pentax-Discuss Mail List.

RE: Popular Photography 31/1.8 Limited test (WAS: Re: Pentax a "best ever prime lens" at Pop?)
No, it's not lines per millimeter, it's their SQF numbers. SQF is Pop Photo's "Subjective Quality Factor". It's a number based on MTF and converted to a system meant to show what you should expect in different size enlargements. It's like a grade in a class you take, where 90 + is an A, 80-89 is a B, etc. It's just meant to make it easier to see where the strengths and weaknesses are, and see how big an enlargement you can make before you lose grade A quality.

> And what exactly do they say about this lens? > > Pål > - > Popular Photography never says that an advertiser's lenses are bad. Still, the writer seemed especially effusive in praising the 31. I go by the numbers in their MTF tests. According to these numbers, the lens is consistently sharp at all apertures from 1.8 to 22. One would have to go to very, very large print sizes to detect a difference by eye. The article also says: well-built, minimal distortion, accurate exposures, light fall-off gone by f2.8. And as we would expect from any Pentax lens, slides were sharp and contrasty, and flare was well-controlled. The article points out that the fixed hood prevents use of square filters.

Re: Pentax a "best ever prime lens" at Pop?
There's no article, just reviews of the three prime lenses (including the 31 limited), plus a review of a zoom. There's also a review of a Voigtlander camera, which comes with the reviewed Voigtlander lens. In the camera review they do say that the Voigtlander lens may be the best prime they have tested. On Pop Photo's online discussion forum the managing editor does clarify that the three primes reviewed are what the cover refers to. I think it's sloppy. I'm reading through the issue now. It is filled with writing and typesetting errors. Either the copyeditor was out sick, or they have just cut back on copyediting to save money. Either way, the magazine is annoying to read. Peterson's has had the same problem over the past few issues.

Pentax a "best ever prime lens" at Pop?
I just happened to pause at a newsstand long enough to note that: (1) The cover of the new Popular Photography features something like "we test the 3 best prime lenses ever" (2) The inside cover indicates that the lens test section is the article indicated on the cover (3) Unless I missed something, the only three prime lenses tested in that issue are the new 45mm from Nikon, a new 50 from Voightlander (?), and the new 31mm Limited lens from Pentax.
