Hi Fabien,

Yes it is possible to put your KR onto a telescope.

Now how it's done and what adapters you would need, I don't know because I haven't looked into doing this before.

Get a DA 35mm 2.4 AL

Bonjour,

Best "bang for the buck" in the Pentax stable ... hands down!

See PF user review = Overall grade of 9.26 = SMC Pentax-DA 35mm F2.4 AL Reviews - DA Prime Lenses - Pentax Lens Reviews & Lens Database

PF grade of 8.2 (under-rated IMHO) = Pentax-DA 35mm F2.4 - Review - PentaxForums.com

Like a fast 50mm perspective of SLR film days ... it's great!

Bon courage, John le "Green Grenouille"

As the owner of a SMC-Pentax FA 35mm F/2, I can say that if the new DA L F/2.4 is even half as good, it's the bargain of the century. It's a great prime for a DSLR. It's a little slow for a normal lens, but I'm sure the sharpness and rendering make up for it in spades. Of course, I have my 35 for both film and digital photography, so I"m not really likely to get the new one.

I purchased a K-r recently in a bundle consisting of the DAL 18-55 and 50-200 kit lenses. I soon sold them and replaced them with the DA WR versions which have much better build quality and are less flimsy and fragile with smoother focusing and zoom action (though still all plastic). They also have metal mounts instead of plastic. And the Quick-Shift Focus system which is great. And also very affordable. But of course even these plastic DA lenses have nowhere near the build quality of my SMC-M and SMC-A lenses. And their optics are also not as good. The DAL lenses feel like toy lenses. It is about time ALL Pentax digital SLR cameras and their lenses were all metal (maybe with a thin polycarbonate coating as in the Pentax 645. Say NO to plastic! Compromising on build quality is a sure way to oblivion.
Hm... I would say Pentax kit lenses are pretty solid... Have you hold a Canon kit lenses before? that is what I would call a kit lens....

Medium Lens

Dear All,

I would like now to buy a lens medium range, something like 18-200 or so,

I have found these two
Sigma 18-200mm f/3.5-6.3 II DC HSM Lens for Pentax AF 882109 B&H 18-200mm, and
Sigma 18-250mm f/3.5-6.3 DC OS HSM Autofocus Zoom Lens 880-109 18-250mm,

would any of these work well on my K-r?.........

Many thanks!

Fabien

There is no compatibility problem, but many design compromises. If you are in need of very versatile lens then go ahead, otherwise choose something with less zoom range.

The older DA18-250 and its Tamron twin are usually considered better than those Sigmas or any 18-200s. The DA18-250 is my basic lens; my other 239 lenses are all specialty items. It is just the most flexible of lenses, able to go from wide context to tight detail quickly. No, the optics aren't perfect, but the IQ of a missed shot is zero. It is great when traveling, or when you just don't know what to expect next. It is NOT great at longer focal lengths in low light, but no consumer-grade superzoom is. Out of production, but widely available used, usually around US$400+.

If you don't need that wide a range, consider the DA55-300, very well-liked. The DAL version has the same optics but fewer features and lighter build, and costs rather less. Many people are happy with a DA18-55 plus DA55-300 kit. I personally don't like that pairing, because I shoot a lot between 35-70mm and I hate swapping lenses around 55mm. So if I take my DA18-55 and Tamron 60-300 out for a day, I also have my F35-70, the smallest zoom Pentax ever made: agile (VERY fast AF), sharp as a bag of primes, and cheap at around US$50.

If budget is a problem and you don't need wide angles, consider older zooms like the Tamron 28-200 (AF) or a Tokina 35-200 (MF). If you want wider and newer, look at the DA18-135. If you want SHARP and can handle MF (manual focus), look for a Vivitar Series 1 70-210/2.8-4 in PK-A mount. Are many possibilities. Happy hunting!

Oops, I made a mistake. Current count is 241, says my database.

As I said, I'm an occasional trader on eBay. My DB shows I've sold another 120 lenses. That helps pay for the keepers, hay? And I own 45 cameras and have sold another 30. When I get off my butt (maybe next week) I'll put maybe another 20 lenses up for sale, and some electronics (Zenith TransOceanic radios, Roland analog synth, MiniMoog, Tascam portastudio, etc). If I don't succumb to a NEX, my personal lens inventory may stabilize around 200. With a NEX, I'm doomed...

Of my current lenses, about 2/3 are 'camera' lenses (PK, M42, M39, adaptations, etc) while the rest are enlarger or projector or process lenses, or other lenses that must be mounted on bellows|tubes|helicoid, or multi-element adapters or converters -- or stuff that will need a NEX to mount on. I'm preparing for doom already. Shoot me now.

One excuse for this accumulation: I'm not a collector, I'm a lens librarian. Comes in handy when questions arise here.

I think the 18-55mm AL II is a good choice
