Lens Review Date: January 8, 2007 I can recommend this lens: Yes | Price: $109.00 | Rating: 5 

Pros: inexpensive and plentiful
Cons: none

I purchased this lens rated in LN- condition from KEH in January of 2005. At the time, in the late '70s and early '80s, it was the 'standard' wide angle lens that people purchased if they didn't have the budget to get the more expensive 28/2.8 wide angle lens. As such, they are plentiful and readily available and are fairly inexpensive on the used market.

Construction quality is outstanding, as are all M series lenses. Optical quality is certainly quite acceptable.

I haven't used this lens much because most of my shooting opportunities and interests tend more to the telephoto than wide-angle. In the subsequent time frame, I also purchased the FA35/2.0, so have little need for the M35/2.8 these days.

It is a good little lens, and perfectly acceptable for those on a limited budget. You won't be shortchanged using the M35 rather than the newer versions. Your only limitation is that you will have to use the lens in manual exposure mode (or Av if shooting at f/2.8). And of course, you will have to manual focus. Just like the good old days.

Recommended. Only given a 5 rating because while it isn't really outstanding, neither is it inadequate in any way. It is a 'good' lens, nothing more, nothing less.

Lens Review Date: September 10, 2007 I can recommend this lens: Yes | Price: $120.00 | Rating: 7 

Pros: small, relatively fast
Cons: nothing outstanding

M35/2.8 is one of those quiet performers that nobody seems to rave about.

It is a solid performer. It is sharp enough wide open and very sharp by f4. Very good contrast.

That said, it doesn't seem to have any point that "stands out", everything seems to be in the good to very-good area but no one single outstanding point.

So if you are looking for a good solid, no non-sense performer, I can recommend M35/2.8.

By the way I have only used this lens on dSLR.
Lens Review Date: April 18, 2008 I can recommend this lens: Yes | Price: $76.00 | Rating: 8 

Pros: Good build quality. It has the "M" feel. 49mm Filter
Cons: It's a "M" short for manual everything.

I have only had the lens a few weeks and have been using it on my K100D. The pictures have been sharp with good color saturation. It makes a nice standard lens for the digital camera. My opinion is that it's sharper and has better contrast then Pentax's DA 18-55mm. I would say it is on par with my M-28mm f3.5 for overall picture quality. This is being said without doing a formal test.

Lens Review Date: May 7, 2010 I can recommend this lens: Yes | Price: $80.00 | Rating: 8 

Pros: Sharp w/ good bokeh, value for money
Cons: Shutter blades get sticky easily due to the lubricant "leak" on to the blades holder

This is one of those forgotten lenses - a great performer but seldom got mentioned or recommended anywhere. I've used all 35mm prime lenses by Pentax except the 35/1.4, this M35/2.8 can easily perform as well as any other 35mm lenses, other than the K35/3.5 which is really a great performer.

If you happen to get a good copy (no oily sticky blade), and if you are confident w/ using full manual lenses, just enjoying using it don't need to look for another better one.

Lens Review Date: October 27, 2010 I can recommend this lens: Yes | Price: $45.00 | Rating: 8 

Pros: Optical quality, built
Cons: Nothing for me...

I just want to point out that while many rave about its A version and pay 2-3 times more for that the two lenses are actually the same lens design only in different bodies. It seems that Pentax only renewed its physical design but left everything untouched.

So if you do not mind the lack of A setting and you can live without the plastic exterior of the P-A 2.8/35mm then get this one instead. It is as good optically as the A version but better built. I have both so believe me.
The "A" might have had a touch of upgrade coating-wise but it is not obvious on the pictures taken (at least on film).

Lens Review Date: November 4, 2010 I can recommend this lens: Yes | Price: $52.00 | Rating: 9 

Pros: color, sharpness, easy focus
Cons: none
Sharpness: 9    Aberrations: 8    Bokeh: 7    Handling: 9    Value: 10   

I own a Pentax SMC-M 50 1.7 and a 28 2.8 and this 35 2.8 is just as sharp as either wide open. I am really surprised this lens is only rated 7ish.

It seems to focus easier than either of the others using manual focus on a DSLR. This, IMHO is the i perfect walking around lens...

Lens Review Date: November 9, 2010 I can recommend this lens: Yes | Price: $60.00 | Rating: 8 

Pros: sharp, short minimum focus distance
Cons: large in comparison to the M40, mechanism vulnerable to sticking
Sharpness: 8    Aberrations: 8    Bokeh: 6    Handling: 8    Value: 8   

Excellent sharpness, comparable to the 1.7/50mm, slightly less sharp.

On film, the FOV is perfect, and more normal to me than the 50, with a real feel of depth to photos, as if you are there in the scene again. Great for portraits, provided you like faces which are made of my baby are funky with this lens. Starts to be possible to rely upon depth of field and hyper focal focusing.

Practically though, I find that I am more likely to reach for a 28 than the 35 if I want something wider than the 50. Given the 50's are capable of such outstanding bokeh, the 35/2.8 doesn't see that much use. Story might be different on digital I guess...I am using film.

Lens Review Date: January 22, 2011 I can recommend this lens: Yes | Price: $80.00 | Rating: 9 

Pros: Sharp wide open. Colors are great. Easy to focus
Cons: Not so easy to find

This is a fun lens to use because it is easy to focus compared to my SMC-M 50mm f/1.4, but still gives quite the same quality. Colors are rich and deep. I can get close enough to capture detail with this lens, a sharp performer too, even wide open. Stepped down it gets sharper. Bokeh is pleasing.

Here's a taste:

Lens Review Date: January 22, 2011 I can recommend this lens: Yes | Price: N/A | Rating: 7 

Pros: light, small, versatile, attractive FoV
Cons: not too sharp, some distortion

I used this lens for over 20 years as my main optics. I also used the 2/85mm, but for specific purposes, and while I had the 4/200mm, I rarely used that focal length (all on film).
The field of view is attractive (on film or FF), and the lens is very versatile. I did not have the money for the 1.4 or even 2.0/35mm at the time, although I later acquired the latter as well. Nonetheless, it served its purpose, but in retrospect I can see that it did not shine as some Pentax lenses do. It certainly doesn’t have the wow factor. Not in sharpness, colour rendition, or boqeh.
Mechanically, it has been flawless. Very sturdy and unlikely to give up any time soon, such is the built quality. Yet I would search for another 35mm were I in the market for one today. I'm not, as I now have the Pentax 645-A 3.5/35mm, which is lightyears ahead.

Lens Review Date: July 23, 2011 I can recommend this lens: Yes | Price: N/A | Rating: 9 

Pros: Small sharp and the right focal length
Cons: None really

This is another one of Pentax's excellent 35mm offerings. On digital it has an appealing focal length, and withthe coatings and general design excels at sharp images wide open and 1 stop down we are into ultra-sharp. Contrast is very good and the size is terrific....very small.

Lens Review Date: June 27, 2012 I can recommend this lens: Yes | Price: $150.00 | Rating: 10 

Pros: sharpness, contrasty, great on film
Cons: none
Sharpness: 10    Aberrations: 9    Bokeh: 10    Handling: 10    Value: 10    Camera Used: K-r   

Optically identically to the acclaimed A35/2.8. The difference in review score here may just be a matter of sample variations.

I must have a pretty darn good copy of the lens. It's contrasty wide open with excellent sharpness across the frame. Comparable to M50 1.7 in terms of sharpness. It's close to a normal lens, a little bit on the long side, when used on APS-C. Mounted on a film camera, it becomes a wide angle lens. I prefer the FoV it delivers on film more than APS-C. Something to consider if you are also a film shooter.

I've not seen this lens on sale often. The M28s are a lot more common in the used market.

Lens Review Date: September 14, 2012 I can recommend this lens: Yes | Price: $60.00 | Rating: 10 

Pros: that magical fov in crop land
Cons: zilch


I kind of collected this just because I had the 28 M, and a 50 M at either end, turns out the (on a crop) the 50 feels to portraity, and the 28 a little fickle to focus. (Slowly developing a lens collecting persuasion here..)

Can't explain it, why the 28mm feels fickle that is, but in regards for general use, the 35mm just feels good.

I suppose it's having started with a 50mm on film, the 35mm covers the same amount of area so here I am in familiar territory

Can't fault it wide open, out of focus areas are clean, its a ripper

Lens Review Date: November 20, 2012 I can recommend this lens: Yes | Price: $50.00 | Rating: 7 

Pros: Small, good FL both for 24x36 and APS-C
Cons: Flares a bit
Sharpness: 7    Aberrations: 8    Bokeh: 5    Handling: 10    Value: 9    Camera Used: MX, LX, K-5   

I got this lens as part of a lot. My copy is in good condition, except for a dent in the filter thread.
This is a nice performer, and I say that after having sold my DA 35mm Limited. Compared to it, of course:
- less contrast, more prone to flare
- less sharp when focusing on closer subjects
- no macro ability (!)
But, when focused on infinity or hyperfocal, this little cheapie holds its own very well! In practice I have a hard time seeing any difference at all in these conditions.
To sum things up, this is THE lens to get if you're on a budget and want a 30-35mm prime for general purposes.

Lens Review Date: March 21, 2013 I can recommend this lens: Yes | Price: $30.00 | Rating: 7 

Pros: Size, build quality, sharpness, color rendition
Cons: long focus throw
Sharpness: 8    Aberrations: 8    Bokeh: 5    Handling: 3    Value: 6    Camera Used: k20d   

This is my best lens, i got this lens because of the "equivalent" to 50mm, but that's a load of lies

it has nothing to do with a real 50mm, even if i use my 50mm @ f2.8
i honestly dont know why people say "if you want a real 50mm on a crop sensor, you should get a 35'mil!
another think it has nothing to do with a 50mm is the focus throw, since it's a manual lens you'll be using the focus ring alot (...) in the 50mm it goes like ...

50mm /0.45 /0.5 /0.55 /0.6 /0.7 /0.85 /1 /1.2 /1.6 /2 /3 /5 /15 /*infinity
35mm /0.3 /0.35 /0.4 /0.5 /0.6 /0.8 /1 /1.3 /2 /4.5 /*infinity
you can see it skips from 4.5 to infinity unlike a real 50mm.
so if you want to get a 35mm for the "50mm feel" do not get this or any other 35mm lens

i got it as an extra when i went to buy my smc-m 50mm f1.4

The sir who sold me the lens was needing money and he kindly sold me the lens for 25eur along with the 50mm for 50eur
i really didn't want this lens, i just wanted a faster 50mm as i was getting tired of my smc-a 50mm f2.0
(i do ALOT of street night photography)

but in a sense i thank those people that said to get a 35mm to replace the fullframe 50mm, if it weren't for them i would have never came across this beauty, i use this lens more in daylight than i use anyother lens

from f5.6 to f8 this lens is so amazing, i never seen anything like it, even the 50mm doesn't give me such good pictures. this lens came riddled with the aperture blades problem, but nothing to hard to fix
came with original box and lens covers.
i honestly can't imagine how a famous FA limited or any STAR lens work since this is the best thing i've ever seen
(no pentax users around here to meet and test lens on my camera, im all alone eh!)

picture of the lens in its original leather case (click for fullsize)

picture of lens case top cover, reads SMC PENTAX 2.8/35 (click for fullsize)

One of the many beautiful photographs i did with this lens (click for fullsize)

posted here in the pet gallery, the bokeh is only usuable up close, but you dont want people shot's at this distance, they look weird and bloated in comparsion to the 50 mil

Pros: Small size , optics and helicoid very good
Cons: No
Sharpness: 9    Aberrations: 9    Bokeh: 9    Handling: 9    Value: 10    Camera Used: KM , ME   

I have the M-2.8/28 mm and the M-2.8/35 mm . At short distance untill 5 metre's there is not much difference between the two lenses , but if you do a landscape the M-2.8/35 mm is a real winner . At 1:5.6 even the far corners of the 35 mm negative are very sharp , so this 35 mm is very usefull lens for handheld photography with a 100 iso black and white film and a orange filter . It is a great lens .
