Pentax K10D, SMC Asahi Takumar 135mm f/2.5 (manual focus), ISO 100,  f/2.5, 1/250 sec, +2/3 EV, IS on

Playing around with my “new” Asahi Takumar 135mm f/2.5 I picked up from KEH for $60. This is a very cool little lens. It’s fully manual but I’m finding that if I shoot it wide open I can use Aperture Priority mode and still have simple control over exposure compensation. I’m planning on playing around a bit with stop-down metering in manual mode using my K10D’s Green Button.

Pentax K10D, SMC Pentax-FA 50mm f/1.4, ISO 125,  f/1.4, 1/60 sec, +2/3 EV, IS on

Been playing around a bit with a Pentax FA 50 f/1.4 lens I’m borrowing. This shot was taken almost directly into the late afternoon sun streaming through the windows on the front of our house. So far I am finding the FA 50 to be a bit soft for my taste wide open (as you can see here) but the autofocus and extra 2/3 stop advantage over my old A series 50mm f/1.7 are nice. There does seen to be a fair amount of purple fringing in a lot of my shots but I have yet to really test the lens with anything more than some plinking around. I don’t think I’m going to do my usual full-on User Review for the FA 50. I’ll probably just do some anecdotal comparison to my old 50 f/1.7 for those people who either have an older manual focus lens and are thinking of upgrading or for those people who are considering their first fast fifty.

BTW, this image was imported into Lightroom using my standard import settings for my K10D. I then selected “daylight” for the white balance and nudged the blacks slider up to 16 to dial in a bit more contrast. Lastly, I cropped it square and rotated it slightly clockwise to adjust for level on the left side of the frame.

Pentax SMCP-DA 35mm f/2.8 Macro Limited User Review

money1

Ever since I started shooting DSLRs with APS-C sized sensors I have struggled to find the perfect go-to lens for the majority of my photos. I love the speed and image quality of my old A series 50mm f/1.7 but the lack of autofocus and relatively tight F0V (75mm equiv.) makes it less than ideal for a lot of my shooting. When my friend Stephen said he was sending me his DA 35mm f/2.8 Macro Limited to take for a spin I was pretty sure that it was going to be the lens I have been looking for. I had read all the reviews so I knew that it was a sharp lens with top-notch build quality. All that remained was for me to live with it for a few days…

Pros:

  • Razor sharp starting at f/2.8.
  • Virtually no flare and very low CAs or fringing.
  • Wonderful bokeh (especially during macro use).
  • Impeccable Limited build quality.
  • Smaller and lighter than most 1:1 macro lenses.
  • Durable*
  • Ultra close focusing capability.
  • Built-in lens hood.
  • Excellent bang-for-the-buck.

*I didn’t test this lens’ durability but my friend Stephen did. Within minutes of opening the box he dropped it from a height of 1M onto concrete. The filter mount ring took the brunt of the impact (note silver filed away area in these shots) but the function of the lens was not otherwise affected. Wow!

Cons:

  • Slow focusing due to extremely long focal range.
  • Lack of focus limit switch (might correct previous point).
  • Focus ring spins during autofocus operation.
  • Included lens cap falls off too easily.
  • Extremely limited stand-off distance at 1:1 magnification (read: “none”).
  • Diffraction may be a problem above f/8 with non-macro shots.

Conclusion:

Turns out this is not the do-it-all lens I’ve been looking for. Now, before all you Pentaxians out there start accusing me of bashing Pentax again, let me explain…

The DA 35mm f/2.8 Macro Limited is one of the best macro lenses I have ever used. It absolutely blows everything away within 2 feet of the front of the lens. I love the natural look the 35mm (52.5mm equiv) FoV provides. I can easily see this being one of the best lenses available for shooting products in a studio setting. If I were still walking the floor at Asian electronics trade shows it would be my go-to lens (lots of close-up shots of products held in my hand). However, the things that make this lens so good at what it was designed to do also make it less than perfect for my everyday use. If your primary interest is up-close hand-held macro photography, look no further. Buy this lens. If, like me, you are thinking that this lens might double as a good medium focal length lens for everyday use, please read the rest of my review and decide for yourself:

Pentax K10D, SMC Pentax-FA 35mm f/2, ISO 640,  f/4, 1/50 sec, +2.0 EV, IS on

This is my 1999 Porsche Boxster sitting in the garage. I opened the door to grab a beer out of the fridge and thought “man that looks nice.” I grabbed my K10D with my new FA 35mm f/2 lens and snapped this shot. Despite the darkness of the garage and the black color of the car, I still had to dial in +2.0 EV to get any detail in the car to show up. The light coming through the garage door windows was just that bright! In Lightroom I simply converted the image to grayscale, cropped and exported this JPEG file.

Another box of goodies arived today. This time it’s some more loaner gear for me to put to the test. What we have here is a Pentax FA 50mm f/1.4 lens, Tamron SP AF 90mm f/2.8 Di Macro lens and a Sigma EM-140 DG TTL ring flash kit. Stay tuned…

About

I'm an industrial designer and an avid hobbyist photographer. People are always asking me "how'd you do that?" So, I decided to create this site as a place to share my experiences and insights about photography, the gear and what it all means to me. I'm not sure if this site will make anyone besides myself a better photographer but I figure it's worth a try. Take a look around and let me know what you think. Thanks for stopping by!
