SMC Pentax 85mm F2.2 Soft

Description:
This is the fastest of the three "soft" lenses. Optically it is very simple with just two elements and thus much different from a regular 85mm lens.

Lens Review Date: October 8, 2010 I can recommend this lens: Yes | Price: N/A | Rating: 9 

 
Pros: Light, sharp (in the middle), great contrast.
Cons:

This is an excellent studio portrait lens.

F2.2 is too soft for most applications, but the centre sharpens up very nicely within a stop or two, which is where most people would use it. This is perfect, as you never feel hemmed in by the degree of variable softness on offer. The aperture ring allows for any intermediate aperture settings to get the softness just right. Not being an "A" lens, you can see the effect in the viewfinder.

The lens produces great colour rendition and contrast, with just the slightest CA.

Although most fast MF lenses work a treat with the AF 1.7x teleconverter, this lens is an exception. The wider and softer it gets, the more hit-and-miss is the AF. Rather than endless hunting, it seems to give a false lock. Manual focus only, and you'll be delighted.

Almost perfect.

Lens Review Date: March 28, 2010 I can recommend this lens: Yes | Price: $520.00 | Rating: 9 

 
Pros: Great creative tool and very versatile.
Cons: Price and 49mm filter thread.
Camera Used: K Series film bodies (K1000, KM, KX, K2, K2DMD)   

The K85/2.2 Soft falls into the specialty lens category and is one odd looking lens. (Pear shaped) It also holds the distinction of being the last “K” series lens introduced (1986) and the only one with a 49mm filter thread. (Other K series lenses standardized on 52mm, 58mm or 77mm filter threads)

The aperture ring has a range between F2.2 to F5.6 and is also used to control the degree of “softness”. At F2.2 the lens is the “softest” and it sharpens as the lens is closed down.

The focusing ring does not have a distance or depth-of–field scale and I found it a little hard to focus as my cameras all have cross-microprism screens. The lens manual recommends an “all-matte” screen. This is also a fully manual lens with no diaphragm linkage, so you need to use stop-down metering but in a different way.

These are the steps when taking a picture:

1) Adjust the degree of “softness” using the aperture ring.
2) Manually focus. (If you change the degree of softness you will have to refocus)
3) Turn on meter and set the shutter speed.*
4) Take picture.


*Due to the K85/2.2s limited aperture range, a camera with “aperture priority” works best. I have used this lens with my KX and K2 film bodies and the K2 is much better, as it has an Automatic shutter setting.

The K85/2.2 uses the “M” series short telephoto lens hood, designed for the M85/2, M100/2.8 & M100/4 Macro lenses.

My results using this lens have been quite good and I also recommend trying this lens with macro extension tubes or a teleconverter. This makes the K85/2.2 quite versatile and it’s not just for portraits. I have also taken pictures of flowers & buildings, using the lens on its own or with the above attachments.

The K85/2.2 is fun to use and will bring out your creative side, like the K17/4 Fisheye or the K28/3.5 Shift lens. I highly recommend it, even though it’s on the pricy side.
