Lens Review Date: January 18, 2017 I can recommend this lens: Yes | Price: $270.00 | Rating: 10 

 
Pros: sharp wide open, fast, great colours, nice focus
Cons: none
Sharpness: 10    Aberrations: 9    Bokeh: 10    Handling: 10    Value: 10    Camera Used: K5IIs, K3, K-01   

One of the very best 35mm lenses Pentax ever made. In some regions it might well be the best.

I own 2 of them and sold my FA35/2 in favor as I prefer the A35 despite the FA being lighter and an AF-lens. The only 35/2 lens which I do find better is the Zeiss Distagon T* 35/2, but this is quite a heavy lens, not at all the lens you chose for light travel. I also have the SMC Takumar 35/2 which is optically identical with the K35/2. There is no question, the DA35 Macro-Limited is a fantastic lens as well, great macro, butů AF hunts due to its macro ability and long focus throw, most of the time I use it manually for that very reason.

At 2,8 the A35/2 is as sharp as the DA35limited but allows F2 and thus is more versatile aside of lack of macro ability. But add a Canon D240 52mm achromatic close-up lens plus an 49-52mm adapter and one has excellent close-up abilities. Or a Canon D250 achromat. Both fantastic value.
Sigma or Pentax achromatic lenses cannot compare.

At infinity the A35/2 is as sharp as the DA35limited. It does not have this special micro-contrast which the Zeiss Distagon supplies. Wide open sharp enough, it allows portrait, particular because
bokeh with its 6 blades is astonishingly nice wide open, I did not expect that.

At F3.5 the A35/2 is as sharp as my K35/3.5 wide open! The K35/3.5 is of course very light and has this special 3-D presentation which it shares with the Zeiss, but it's use is limited. If I would have to chose just one lens, it might well be the A35/2.

I prefer the A35/2 even over the A28/2 (I have two copies of this lens as well, because both, the A35 and the A28 allow excellent DLSR comparison)

Built quality is excellent, similar to the M35/2.

I am aware that a review is very subjective, normally I would rate this lens 9 or 9,5, but due to some rather "of-the-point reviews" it got I feel one has to balance this out. 10 points is what I would give the best Limiteds of the Zeiss Distagon and the K28/2. So a healthy 9.5 it is.

Lens Review Date: June 3, 2015 I can recommend this lens: Yes | Price: $280.00 | Rating: 9 

 
Pros: Sharpness on FF
Cons: None yet
Sharpness: 9    Aberrations: 8    Bokeh: 9    Handling: 10    Value: 10    Camera Used: K-01, K-3, BMD4K, A7s, GH4   

I've had one of these gems for a couple of months now, used for Video/Cinema shooting, and the occasional still.
When I have a 50mm on a full frame A7s, this 35mm gives a close enough to similar framing when on a K-01 or BMD camera with s35 sensor to be able to match the shots between FF and s35.

The K-01 loves it, so does the K-3 - Very easy to do hand-held work with a K-3 and this lens.
This lens makes a BMD camera look better then they are,..
The M4/3 sensor of a GH4 really doesn't take all that much advantage of the lens though - the 35 looks like a 70mm.

Put the 35mm on a Full Frame A7s, and the section of the glass used by the APS-c and s35 cameras is excellent, but there is a fall off in focus sharpness out near the edges of the frame - the sort you wouldn't notice in a still, but do when a person moves partially in to the soft zone in video.

I recommend this lens to anyone shooting FF, s35 or APS-c, it's excellent value for money.
The consistency of the colour transmission also makes it very easy to match colour grades between this and other SMC lenses, especially the 50f1.7, 85f2, 100f2.8 and 135f2.8

Lens Review Date: February 9, 2015 I can recommend this lens: Yes | Price: $189.00 | Rating: 10 

 
Pros: Solid build, smooth focus, sharp, great color
Cons: no auto-focus???
Sharpness: 10    Aberrations: 9    Bokeh: 10    Handling: 10    Value: 10   

I also agree this lens in under-rated. It shines next to the FA 35 F/2 version with a much better build and every bit as good optically. I had owned one for near 20 years before selling it after moving to digital...a mistake. I found a nice example recently at a good price and have been enjoying it very much on my K-3. A previous reviewer calls it ugly. I don't understand at all. Every one of the pre F/FA/DA lenses are beautiful in my eyes and I am so glad to be able to use them on the new cameras. Perhaps there are few reviews simply because it is somewhat rare. It is very nice indeed shot wide-open with a wonderfully smooth bokeh. I have not tested it for CA in extreme lighting. I suspect it will have the usual bit of easily corrected fringing.

The only criticism I have is it is soft at F/2 when focused at infinity. Closer than 30 ft or so and it is just fine. It seems to be optimized for medium to close distances.

Lens Review Date: October 11, 2014 I can recommend this lens: Yes | Price: $300.00 | Rating: 10 

 
Pros: sharp, fast,iq, bokeh, color rendering, optical performance
Cons: N/A
Sharpness: 10    Aberrations: 9    Bokeh: 10    Handling: 10    Value: 9    Camera Used: K5   

First of all, previous reviews of this lens are very strange. Just one rating, only for sharpness category, and it is 7??? C'mon consumer zooms sometimes got better ratings here on pentax forum. Are those ratings some kind of conspiracy by Pentaxian holy order? Masked secret weapon with false ratings?

Second, see ratings for SMC Pentax-A 28mm f/2, that lens got 9.10 overall. But this is a better lens. I tested them side by side and keep this one. Slightly, but noticeably better sharpness, better/easier focusing (wierd, in theory should be opposite?), better bokeh, better color rendering (subjective).

Third this is probably the best 35mm ff lens Asahi/Pentax ever made ( not 30, not 31, just 35 ). This statement is based on expirience with K35f/2, K35f/3.5, M35f/2, M35f/2.8, A35f/2, A35f/2.8 and FA35f/2.

Overall rating should be 9 but I give it 10 because of previous reviews and ratings.

Lens Review Date: April 11, 2010 I can recommend this lens: Yes | Price: $300.00 | Rating: 7 

 
Pros: Wide maximum aperture, build quality, optics
Cons: Rare, front of lens looks average looking
Sharpness: 7   

Got a pristine copy of this rare lens from a good friend. The lens looks very similar to its f/2.8 sibling but just a tad longer in length. Build quality is good and the optical quality is good on my copy. The first impression is the very nice color rendition this lens gives, just warm and punchy. Kinda hard to get the original hood but with the proliferation of generic 49mm metal hoods, this is not an issue. I'm very pleased with the focal length on digital and is ideal as a prime lens for walkabouts. The f/2 maximum aperture (very usable) and 6 bladed aperture does make a difference bokeh wise compared to the cheaper and more plentiful A 35mm f/2.8.

UPDATE: When this lens was tested against other Pentax 35mm lenses, the resolution was found to be worse compared to the newer Pentax lenses. For this reason, I have changed my recommendation.

Pros: Great build quality, IQ, size, good bokeh and DOF & it's beautiful
Cons: none other than it's fairly rare

First of all, I think the Pentax-A series lenses are great looking and most of them have great build quality and IQ. Also, most of them are fairly compact and have a great fit and feel on modern DSLRs.
The copy I have is sharp wide open and only gets better when stopped down. The color and contrast are great throughout the aperture and focus range and bokeh is good for the focal length.
DOF is predictable and consistent and the lens is a pleasure to use, especially with a split-image focusing screen. The focus ring rotates @180 degrees which makes minor adjustment easy.
It's small and compact for a fast lens, but not too small, light but not cheap or "plasticky".

Highly recommended if you can find it.

Pros: Great focal length on digital, decent build, really good all rounder
Cons: Ugly

I was nervous about buying this lens as I couldn't find an awful lot of information about it out there on the net. The screenshots I could find showed a fairly ugly lens, and I was braced for disappointment.

In fact, when it came, I realised it's a gem. It's very sharp, and quite useable even wide open, and the bokeh is nice. I don't think it's going to set the world on fire, but I absolutely cannot fault it. If this was the only lens I could ever have I'd shrug my shoulders and say "fine", because it really does the job.

No complaints from me.
