Pentax vs Canon lenses 2009

by Enche Tjin on September 28, 2009

Pentax has a solid and interesting lens lineup. Pentax collection is not as large as Canon or Nikon, but Pentax has many unique lenses with solid image and built quality. All Pentax DSLR cameras has built-in image stabilization (Pentax calls it Shake Reduction technology). So every lenses mounted in Pentax camera will has that benefit.

Pentax has several class of lenses:

  • Consumer grade (DA lenses),
  • DA* (DA star): weather/waterproof lenses
  • DA Limited: high quality small lenses
  • FA lens: Pentax lenses from 35mm (full frame) film camera era which is compatible with Pentax digital SLR cameras.

Note: Supersonic Drive Motor = Smooth and quiet auto focus lens. It is reported that SDM is slower than Canon USM (ultrasonic motor).

You may notice not all the lenses are on the table, especially old/legacy lenses. I do it on purpose because many legacy lenses are not available to buy new, and the old one might be pretty hard to find.

In zoom lens category, Pentax has a complete lens line up from fish eye to superzoom lens. Pentax has several great value for money lenses in this category such as Pentax 17-70mm f/4 which is better than Canon 17-85mm and DA* 16-50mm f/2.8 which is high quality waterproof Pentax zoom lens. Compared to Canon EF-S 17-55mm f/2.8, Pentax 16-50mm offers better value for your money. Recently, Pentax also launch consumer lenses with WR (water resistant) along with their flagship camera, Pentax K7.

Pro grade zoom lenses

Pentax has some unique lenses in this category, 50-135mm and 65-250mm. These lens’ focal length is designed to mimic popular focal length in full frame DSLR cameras. 50-135mm is equivalent to 75-200mm while 60-250mm is equivalent to 90-350mm. As we know, Pentax does not have any full frame DSLR cameras, unlike Sony, Canon and Nikon.

In my opinion, Pentax is lagging quite severely in this category. Pentax need more lenses to fill the gap such as fast (f/2.8) telephoto zoom and high quality super zoom lens which is very popular for travelers.

Canon vs Pentax prime lenses

Pentax shines in this category with Pentax DA Limited prime lenses. This lens is tiny, lightweight yet their image and built quality are exceptional. Unlike Canon or Nikon brand, Pentax has built-in stabilization in their cameras. So you will get this advantage when using Pentax prime lenses. Last year (2008), Pentax prime lenses are cheaper, but due to global financial crisis and Yen appreciation, the price rises significantly. But still, Pentax prime lenses offer a good value for money.

Pro grade prime lenses

Unlike Canon, Pentax does not have many hi-grade prime lens which has big aperture such as f/1.2 or f/1.4. It might be because Canon camera has a bigger mount. Today, Pentax still relies on FA lenses from the film era: 31, 43 and 77mm. Like telephoto zoom category, Pentax needs to add more collection to compete with other brand. Prime lenses are good for many application such as sports, portraits, wildlife, etc.

Overall, Pentax lens collection offers good value for money especially because Pentax cameras has built-in image stabilization. Pentax lenses are also interesting, such as the DA Limited pancake lenses which is very small but high quality. The main weaknesses of Pentax lens collection will be in telephoto zoom and prime category. If Pentax works on this category and built lenses that has faster auto focus and big aperture, then, many sports or wildlife photographers will find Pentax an interesting system to look at.

I recommend to get Canon and Nikon lenses at Amazon.com or BH Photo Video. They have stellar services and very competitive price.

The Pentax lens lengths are sometimes just hard to get used to, like 50mm-135mm for example. Not wide, not that long.

Jason, 50-135 is the exact field of view as 70-200 on film but weights half of it.
Current pentax lenses are optimised for crop, while canon doesn’t bother releasing such lenses.

The closest to the spec might be Sigma 18-250mm OS.

Peppo June 17, 2010 at 5:49 pm

Hello,
Apologies…am I missing something? you appear to repeat entries for the Pentax 16-50mm f2.8 in consumer zoom and pro zoom lists but with different scores for IQ. Can you please clarify

regards
