It's very unfortunate, not to upgrade the outdated screw drive focus for this lens , like seen on the Pentax DA 18-135.

By marike6 (6 months ago)

Pentax has some great DA primes, but their last generation screw driver zooms really do need to be updated. If Pentax has no interest in modernizing their zooms, they should bring the prices back down to earth. All of the competition's lenses features whisper quiet AF motors for similar (often cheaper) prices.

By karannz (6 months ago)

Are the competition's lenses also weather Resistant at this price?

I'm in the market for a new 35mm, was thinking of getting the Sigma Art but it is just too expensive for my needs now even though it is an excellent lens.

Thinking of getting the DA 35mm f2.4, the HD 55-200 was not in the roadmap, will wait for the HD 35 f2.4 if ever there will be one.

Or you can get this one:

Would love it since I already have the DA 40 and 70 Limited but for the money, the Sigma Art is technically better and the DA 35 f2.4 focuses much quicker.

By sbc (6 months ago)

Nice, but I was hoping for the rumoured DA 18-70 f2.8 instead.

Pentax is rolling out HD coating over it's line up, it's not really a new lens it has different coating and wr protection. Therefore these updates are not on the roadmap. There probably will be one or two new lenses later this year.

By Edgar_in_Indy (6 months ago)

Same old optics huh? I've owned both the DA 55-300mm and the DA version, and while they were both OK optically, that's about as much credit as I would give them.

I wish Tamron would stop their Pentax boycott and release the new 70-300mm VC in K-mount. That lens puts the 55-300mm to shame.

Exactly. I had the 55-300 too, but I sold it in order to get a faster telezoom with f2,8. Since Pentax makes none, I have to look at Tamron 70-200/2,8.
On the other hand the DA 55-300 was really lightweight and portable, ideal for chasing wild animals (in good light of course). And weather sealing is very useful for this purpose too.

"faster telezoom with f2,8. Since Pentax makes none,"

What about 50-135/2.8 and 80-200/2.8?

The 80-200mm f/2.8? Really? How many years has it been since that lens was in Pentax's lineup?

That leaves just the 50-135mm f/2.8, which is not a very long lens, and suffers from a very slow and unreliable SDM autofocus motor.

This is good news. The DA 55-300 is a sharp lens. I have often wished it was weather-sealed to go along with the weather-sealed camera body (K-5). Next, I would love to see some weather-sealed limiteds and DA primes...

By cgarrard (6 months ago)

That's exactly what I thought. I like the 55-300mm Pentax, one of my favorite all around zooms. It's a bit pricey at that SRP though.

Can't see my self heading out for this in a hurry, but agree my version of the DA-L is pretty sharp. Just another string to their bow and makes a lot of sense. The new HD coatings will be interesting to see reviewed and particularly on the K3....

Sorry I fell asleep at the key board due to the soporific sound of crickets chirping.

Not bad innovation, but I'll keep my older DA55-300 :)

Pentax should RE-build FA*80-200/2.8.. that will be better.
