Takumar 135mm F2.8 Bayonet

This is a manual, non-SMC Pentax lens.
This lens has no "A" setting and thus does not support aperture automation (Tv and P modes), but only Av and M exposure modes.

Lens Review Date: April 11, 2018 I can recommend this lens: Yes | Price: $40.00 | Rating: 8 

Pros: Portraits, skin tones, warmth, soft-ish
Cons: soft-ish, limited use on portraits
Sharpness: 7    Aberrations: 7    Bokeh: 8    Handling: 9    Value: 9   

The lens is great for portraits. Very kind on the skins, a bit soft which is good as it forgives imperfections.

I also have the M 135mm/3.5 and find the latter to be an overall superior lens.

However, again, portraits... I'd choose the 135mm/2.8 bayonet.

Note - The last picture, of the moon, was taken through a closed window at my NYC apartment. Honestly given the circumstances, not a bad shot...

Lens Review Date: June 3, 2015 I can recommend this lens: Yes | Price: $35.00 | Rating: 9 

Pros: Sharp, compact, good colours and pleasant bokeh
Cons: some purple fringing on backlit objects
Sharpness: 9    Bokeh: 8    Handling: 10    Value: 10   

This lens is a steal! As far as I can tell it is the same optical format at the Pentax A 135mm f2.8 but without the automated aperture and perhaps inferior (though still multicoated) coatings. It appears sharp from wide open and very sharp when stopped down. The images are contrasty and the colours look great.

I have three manual focus 135mm lenses, the Steinheil Quinar f2.8, the Jupiter 37a and this one, which I picked up for peanuts on ebay. Of the three the Steinheil gives me the best images, but it is twice the size and weight. The Jupiter is also a great lens, but the Takumar beats it in handling. The wider aperture makes manual focusing easier and the slide out lens hood is just so easy. The Takumar is also the smallest and lightest of the three making it very easy to slip in my bag. But enough words ... time to let the images speak for themselves.

Lens Review Date: March 21, 2014 I can recommend this lens: Yes | Price: $90.00 | Rating: 9 

Pros: An affordable 135mm 2.8.
Cons: No "A" on the aperture ring.
Sharpness: 9    Aberrations: 8    Handling: 8    Value: 8    Camera Used: Pentax K5ii and Q7   

I like this lens. I already had an M 135 3.5 so wasn't sure if it was worth getting this. The M 3.5 scored higher on this forum, and the two more positive reviews here haven't used the lens. But I wanted a 2.8, so I bought it.

Naturally, it is a little bigger/heavier than the M 3.5. But still not huge.

I am not an expert tester or anything, but from simple comparisons, my thoughts - comparing the two lenses:

I like the colours on both about the same. Didn't notice a significant difference.

The 2.8 seemed a little sharper to me. (I can't remember now how I did the comparison, but I think this was my conclusion even comparing both wide open.)


I'd say the purple fringing was a fair bit better on the 2.8.

At f8, both were pretty good (at least in the conditions I did the test in).

Shooting wide open, however, the 2.8 was significantly better than on the 3.5.

More subjectively, I think I prefer the feel (physically) of the 3.5, and certainly the fact that it is smaller. All things considered though, I'd have to say I prefer the 2.8 lens.

More expensive, and a bit heavier, but worth it for the 2.8, slightly better sharpness (I think) and less purple fringing.

I just won this lens at an eBay auction ( 27.95 including shipment), and it may take some time till I finally get it. But I want to add some comments beforehand.

1) Some time ago I met a retired professional who told me that in the eighties an official Pentax dealer showed him a written internal paper by Pentax which informed that, since 1979/1980, ALL Pentax/Takumar lenses not labelled as "SMC" are nonetheless MULTICOATED. They would just lack the patented SMC coating, but the multicoating should not be worse than that of the competitors. If this is true, it would include most of the Takumar Bayonet lenses.

2) Also some time ago, I downloaded a PDF with a detailed real life comparison (including some marginal chart tests) of the Pentax 135mm range lenses. I think I got it from a link in some other forum, if I can find out the URL, I will add it to this comment. His results differ in some respects from the usual findings in forum posts.
Winner in this test is the SMC-F 2.8/135 [IF], closely followed by the SMC-A 2.8/135, which is not too surprising, as they are the newest. But for the rest, there are some amazing results (which could be caused by the fact that all these lenses are old, used, and probably would need a factory adjustment). In this test the Takumar 2.8/135 [Bayonet] is, together with the SMC-M 2.8/135, very near to the winners! It also was on par with the SMC-M 3.5, and in most respects better than the generally highly praised SMC-K 2.5/135.
Also astonishing: the missing SMC coating did not show ANY bad effects in real life shots with the Tak 2.8, but was VERY visible with the Tak 2.5! Could it be Pentax changed the coating during production without mentioning it? Also, the Tak 2.5, wide open, has significant loss of resolution against the Tak 2.8, and PF and other colour errors are SIGNIFICANT worse at all apertures.
So, according to these results, one could think the Tak 2.8 could be a better buy than the Tak 2.5.

By the way, he also compared to the Pentax DA 4-5.6/55-300mm at 135mm, which was no match to any of the Primes in any respect.

Added: Just found the URL.

Unfortunately everything is german only, but the result sheet (conclusion at the end) should be fairly self-explaining.

I can't really put a full review of this lens here as I do not own it and never have.
But I wish to make a few comments.

Basically this lens is the same as the SMC-Pentax version except for the coating.
In some light-conditions it can give the same good result as the SMC-version.

When light comes in from the wrong angle however it can lose contrast, give flare etcetera. This can be suitable for dreamy portraits.

If one remembers that in the '50s and early 60's lenses did not have multicoating either, it is clear that a lens like this can be used to create a similar effect.

That said, it is easy. Learn what the lens can do and cannot do. If you need a flare-free lens that gives always crisp images go for an SMC-version. If you want to use the effect, or cannot afford (then) or find (now) the SMC version, this one is a good choise.

The 2.5 version can be expected to be slightly better than the 2.8 version.
The 1.8 star and 2.5 (SMC) were top of the bill then whereas the 3.5 (both 3.5 K and M versions) and the more recent 2.8 (A, F and FA) version were clearly the cheaper (but still good) counterparts for the average user and for those that needed to travel lighter.

Lens Review Date: July 7, 2008 I can recommend this lens: Yes | Price: N/A | Rating: 8 

Pros: Fast, great build quality, built-in hood
Cons: Not really sharp wide open
Sharpness: 7    Aberrations: 7    Bokeh: 8    Handling: 9    Value: 8   

135 mm with f2,8 is a very exciting combo. Sadly this lens is no macro lens, and cannot focus really close. When wide open, it is decently sharp, but not great. It becomes quite sharp at f4, and remains that way at least up to f11. At f16 it becomes visibly softer.

Images look good. I think the contrast is what bothers me most, but it's not BAD, just not fantastic. The problem is that I can compare it with a Vivitar 70-210 f3,5 and it cannot really hold its ground against it. But then the Vivitar was selling for 700$ CND thirty years ago, so it's not a fair comparison at all.

Build quality is surprisingly good. After 20+ years, the focus ring is smooh, the body is clean, the aperture ring is fluid. There is a built-in hood that works very well. Some people claim that this lens is not coated; that is false. It is coated, just not SMC.

Manual focus is efficient, the focus ring has a long throw and feels well damped.

I'm glad to have this lens, and will probably use it more in the future, if only to experiment and see what I can do with it. At the end of the day, having a 135 mm f2,8 lens is always a good thing. And this lens is certainly not the doorstop some people claim it is.


Edit : I used this lens at a wedding a few days ago, between f4,5 and f5,6 (where it's supposed to be very bad according to some), and it can shine as a portrait lens! I'm revising my evaluation from a 7 to an 8. Here's what it can do:

Creamy bokeh, beautiful contrast, sharp enough. I can't ask for more...
