Hey, welcome! The good news is, those are probably the weakest lenses in the Pentax lineup, so just about anything you buy will give you better image quality and features
Originally posted by Callist This is a Pentax forum and some would say I should expect a biased opinion but is the brand Pentax worth staying in at the moment with the way the company has a record of being sold and bought - will Pentax stay strong?
Meh, Nikon is owned by Mitsubishi and Canon is a printer company, Olympus had all sorts of problems in its ownership structure (some scandals about this), and Sony basically bought Minolta and Zeiss brand names but still has no soul. But honestly, how much are you going to invest into Pentax? Thousands upon thousands? Also, you have the K-r and kit lenses for years now, and its still serving you well. A new camera being released or the company going bankrupt doesn't mean your camera will stop working.
But to answer your question, Pentax seems to be doing fine. There is a joke in these forums about people jumping to the conclusion that "Pentax is doomed" after every and any piece of news comes about Pentax.
Originally posted by Callist Am I right in assuming for the K-r that due to the 1.5x sensor ~33mm would be around 50mm give or take or have I not understood the sensor size theory correctly?
I don't know what ideas you have in the background. You have to understand that focal length is a lens property. So a 50mm lens from the 1970s, a 50mm lens for medium format, and a 50mm lens for APSC will all give the same field of view on your camera. Because the field of view is limited by the image circle the lens projects, and the size of the sensor. I suggest you simply forget about equivalence, unless you are using cameras with different sensor sizes. That is the only time you need it. For example, if you use a 35mm lens on film it would appear wider than if you put the same lens on a crop sensor camera. Don't go around buying 100mm "full frame" lenses thinking they will be different from 100mm "crop sensor" lenses on your camera. They would be the same. Zoom your 18-55mm lens to 35mm. All 35mm lenses will have that field of view on that camera (approximately, there are also differences in rendering and distortion). Now zoom it to 50mm. All 50mm lenses will have that field of view on that camera.
Originally posted by Callist Would the 35mm prime lens (not Limited) be a reasonable upgrade for a lens or pointless?
The DA 35mm f2.4 was exactly what I was going to suggest. It is much better than the kit lens. It is only pointless if you don't use it. It is a sharp lens, great flare resistance, fast AF, good low light performance.. You can also check the user lens reviews here:

Just to see what the lens is capable of.
Originally posted by Callist I guess my main worry is that with a Nikon/Sony/Canon I would have more lens options and more options within the middle quality/price range opposed to Pentax's no middle range (or so it appears). I really want to make sure the camera path is future proof.
The DA 35mm is under $200, sometimes on sale for under $170. And it will work on the K-r forever. I mean, I don't want to be rude, but some people invest a lot of money into Pentax cameras and lenses, while you seem to be afraid that a $200 lens wouldn't be usable on the latest cameras 10 years from now. Will you be buying the K-3 with the
DA 560mm? How many lenses will you be buying? Pentax is fine. And if not, you can still adapt the Pentax lens on Canon or Sony cameras, and many of the smaller formats as well, if somehow Pentax cameras disappear. And if cameras progress rapidly (with technologies like 100MP sensors, curved sensors, etc.), then all current lenses will be useless anyway, so investments will be lost regardless regardless of brand. The K-mount is the most stable one atm. Canon changed theirs, Nikon changed theirs and has odd restrictions on it, Sony seems to make a new mount and abandon an old one every year..
Yes, Pentax currently doesn't have a prime lens between 21mm and 31mm, but a) one might be announced soon
b) there are many zoom lenses, even high quality ones in that range
c) there are many third party lenses in that range (Tamron, Sigma, Samyang) List here:
https://www.pentaxforums.com/forums/10-pentax-slr-lens-discussion/243556-3rd-...available.html (how many of these will you be buying, that you need even more? Most photographers only get a fraction of all the possible lenses)
d) there are many legacy lenses in that range (all K-mount lenses will work on your camera, even if 30 years old)
I say relax
The DA 35mm is a great little lens for an amazing price, as are the DA 40mm XS and the DA 50mm f1.8. Then there are the limited and * lenses, which have some more features and amazing image quality. You don't need to overthink it. Just go to a store and hold a Nikon and Pentax camera in the same price bracket and decide which one you prefer. Or think of the lenses that you want to use and see which brand offers them at the price you want. Either way, I doubt Pentax would be significantly behind the competition, unless you are planning on spending thousands on camera gear right now and need things like local service centres and many lens rental options.
