My number one goal is almost always to convey beauty. Beauty of the model, of the location, the outfit, and hopefully the light as well. Anything else is just extra layering almost like seasoning to add a little personality/character. I also dislike prudish behavior and comments. Just comes across as close mindedness to me personally.



Duly noted :lol:



An interesting idea but I actually don't consider too many of my images to be overly "mature".



Most of it is content for social media. I have secured model release forms from most of the models so I do plan to release books as well as an eventual YouTube channel.





Thanks for the clarification. Definitely was not clear. As far as the image you are referring to I understand what you are saying but it has actually been one of her more popular images.



Definitions are nice when understood. :)





Thank you for the kind words. I will continue to share images from my photographic adventures.

We've completed our CP+ interview, but it may be another day or two before the video is ready for uploading. One of the things we asked was whether the K-1 line would essentially be the only K-mount flagship, or if they planned to have a model between the K-1 and KP. They reiterated that they are working on a K-3 successor, so the KP isn't and was never meant to be the top APS-C model. However, it seems that the K-3 successor won't be able to come out as early as they had wanted.

DSLR versus Mirrorless

Mirrorless sales were flat for 4 years with one good year last year. Still obviously better than colapsing DSLR sales but with Canon and Nikon jumping in its a pretty crowded market place. The weirdest thing to me about the mirrorless push is the necessity of creating a new mount, especially when it comes to larger formats like FF. Creating a new mount that saves a few mm while having to invest in a whole new range of lenses is just dumb. Stick a EVF on a K mount and you have an instant mirrorless camera system. Maybe we will get a K02 one day.

KP-like mirrorless solution?

The big benefit of a mirror less system is the reduced flange distance to the sensor due to the lack of a mirror. This would require a new lens mount. Which would then require an adapter for the K lenses, thus we would lose the size advantage of it being mirrorless.

I agree with your comments, I like the Olympus m4/3 system, but it’s cost prohibitive. I also like the APSC quality compared to m4/3. I’m not sure how it would sell, but I think a revamp of the K-01 with a new sensor and optional EVF would Check a lot of boxes for people.

The whole EVF versus OVF discussion has been hashed out many times in the past. Most folks just like what they like. I think a lot does depend on how long you have been shooting as to how much help you need from the camera to get decent shots. If you've been shooting for awhile, you should be able to look at a scene and know what is going to be possible after processing your RAW file. On the other hand, if you just shoot straight of camera jpegs and do no processing then maybe the EVF gives you more of a feel for what the camera's jpeg engine is going to produce without chimping. I suppose if you shoot a lot of manual focus lenses, then the EVF has some helps there as well.

I still would be in favor of a K-02 -- full frame sensor, add in an EVF, improve specifications across the board, use a sensor with PDAF points on the sensor. It wouldn't be as thin as the Sony mirrorless cameras are, but it still would be a lot smaller than a K-1. I just don't see abandoning the K mount at this point. It has taken Pentax a really long time to get the lens line up they have and Ricoh has shown no interest in throwing a bunch of money at the imaging arm to speed up the process. Starting from square one it could take fifteen years to develop a full lens line up for a new mirrorless mount. And no, I don't think releasing a K mount to new mount adapter with screw drive motor built in really helps much for that sort of transition.

But, I think most of this stuff is sort of wishful thinking. The K-1 is the only full frame camera that Pentax will offer for the next year to year and a half. Hopefully at that point the full frame lens line up is a little more complete.

What is Ricoh Pentax relationship with Sony's sensor division like?

Well there are several points I can add to the discussion here.
  • Sony is really no longer Sony - Sony has / is in the process of spinning their imaging / chip design and foundries off as a separate stand alone company. They have also acquired Toshiba's imaging subsidiaries (the other source of Nikon's image sensors). So, Sony is pretty much the one stop shopping location for imaging needs. Yes, there are other boutique imaging houses - but, Sony is the big dog on the block. That brings up the question of what "special" relationship Sony Cameras has with the new Sony Imaging - now that they have separate ownership. I suspect that there will always be special connections there, but I also suspect that Sony is not going to be putting off Nikon, Pentax or anyone else with a checkbook containing a positive balance. The customization "partnership" with Leica with their MF sensor, showed that they are willing to deal on custom product$ - especially since they are now out on their own in terms of profit / lo$$ and ca$hflow.

  • Custom Silicon - Intel now has been spinning custom processors for anyone who has the checkbook. They were somewhat forced into this position with the various IP processors houses (ARM, etc.) coupled with other independent FABs willing to build - they are just chips after all. So Google, Facebook, el. al. have been pulling custom versions of Intel processors (mainly to lower power requirements - along with other custom needs). Image Sensors are no different. You can make radical changes or minor rolls. I suspect that with Nikon having larger needs (in absolute numbers) that it's more efficient and cost effective for them to roll silicon, than it would be for Pentax. Now, lets slide up the pipeline to the image processor. Both Nikon and Pentax use the Fujitsu Milbeaut. Nikon uses a custom version of this - while Pentax (I am guessing) use a pretty stock version. It's the software running on the image processor that makes the difference. The custom hardware would just make the software run more efficient and faster. In fact the Milbeaut has incorporated within it a multi core ARM processor.

  • "I R an engineer" - as the saying goes and have designed and developed an imaging pipeline with a custom sensor (OK, it wasn't visible light - but a SAR) - same difference. There is a lot you can do with the sensor's back-end interface, along with the image processing pipeline stream. It all depends on your ability with math and just how attuned you are in the implementation of the algorithms, along with the "black art" of embedded software. It all comes down to speed, and especially power management (which translates to thermal management). All of this is magnified N times when you are designing a handheld device with a battery (with out the extension cord back to the old nuclear power plant). As I wrote a bit earlier (above), I would suspect that Pentax is running on both stock sensors and image processors (mainly due to their smaller production runs), so it becomes important on how knowledgeable/innovative, and creative the mathematicians and physicists are in their algorithm development (specifically in their interest and understanding of photography in this case). Also, very important in particularly is their software engineer's ability to implement (the black magic) within an embedded environment. Then there is the "design for manufacturability". If you can design your "sprocket" to be easily manufactured (and especially tested - maintaining a high level of quality control), that is a hugh win (essentially the difference between a profit and a loss). Your costs can be held down with out (negatively) affecting the quality of production. That becomes pure absolute profit.

I'd like to agree with OP. I love my K-3, but it's too big to carry around all the time, and it's a bit intimidating to some people at family events. I'm thinking of picking up a K-01 to throw in my backpack with a general zoom lens, but since the K-01 is basically a K-5 in compact mirror-less form it would be a downgrade.

I think it's about time Pentax came out with a K-01 successor. K-3 guts in K-01 form would be awesome. Even a mirror-less version of of the K-S2 would grab my attention.
Either way, resolution and low light sensitivity of the newer sensors would be great. (IMHO on camera flash is a last resort, and if I'm bringing off camera flash I might as well use my K-3. Even if the newer sensors have slightly more noise, they have more pixels to compensate in post processing.)

Sticky: How to use/meter Manual & M42 Lenses on all Pentax DSLRs (K-1, K-3, K-5, K-30, etc)
Posted By Adam
Replies: 317
Views: 299,771
Many Pentax DSLR owners want to use M42 screwmount (Takumar) lenses, or M or K manual lenses, on their cameras because of the low cost and relatively high image quality of these lenses.


If you're wondering whether or not these lenses can be used with Pentax DSLRs (or the K-01), then the answer is yes! Pentax as well as third-party manual and screwmount lenses can easily be mounted on any Pentax DSLR (such as the K-1, KP, K-3, K-70, K-S2, K-S1, K-50, K-500, K-30, K-5 series, K-r, K-x, K-7, K10D, K100D, K200D, *ist D, etc.) Just follow this guide!



Modern Pentax DSLRs use the Pentax "K-mount", which employs a bayonet and therefore differs significantly from the M42 screw mount. The older manual M and K (SMC Pentax-M, SMC Pentax) lenses actually use the bayonet, so they will not need an adapter - you can skip straight to the lower portion of this article (starting at "Important!") for information on how to meter with those lenses. Screwmount lenses usually have "Takumar" in their names, and in order to mount screwmount lenses on your k-mount body, you'll need a Pentax k to m42 adapter. Pictured above is the genuine Pentax adapter, which is ideally the one you want to get. Unfortunately, it has been discontinued and can only be purchased second-hand. However, similar third-party adapters are also available. Caution: Many third-party adapters, such as this one, have a protruding flange which will prevent you from focusing all the way to infinity. If you want to buy a third-party adapter (they're generally cheaper), make sure that they don't have this flange. Here's an example of a good third-party adapter.

Once you have your adapter, the next step is to install it on your camera (it can easily be put on and removed on-the-fly). Check out the m42 to k adapter manual. After you've installed the adapter, you'll want to mount the lens. This is done by screwing it into the camera until the lens feels firmly attached. The focusing window and lens ring should line up with the camera just like any other lens. Now that your lens is mounted, let's talk about how to take photos with it.

Important! The hard part is to get the camera to actually fire when a manual lens is mounted. In order to accomplish this, enter your camera's custom function menu, select the "Using Aperture Ring" setting (usually at the end of the menu, #21 on the K-7, #27 on the K-5, #27 on the K-3, #26 on the K-1), and set it to 2 (allowed). Once you do this, the shutter will at least fire, as it wouldn't have with this setting disabled (you would simply have seen an F-- indication on the top LCD/info screen). The setting description should read: 'Shutter will release when aperture ring is not set to the "A" position' when "allowed" is selected. Also note that the mount on the lens must be conductive for electrical current so that it shorts the electrical contacts on the camera body. All Pentax manufactured lenses have a conductive mount, but some third party lenses do not in which case the area of the mount touching the contacts must be sanded down.

K-30, K-50, K-500, K-70, K-S1, K-S2 and K-01 users: make sure you also set your green button "action in M/TAv Mode" to Tv SHIFT. This is found under the button customization menu (page 3 of the main menu) on the K-01 or as a custom function on the K-30, K-50 and K-500. On the K-S2 and K-70, look under the e-dial programming sub-menu under button customization in the record menu.

Finally, ensure that auto ISO is disabled.

At startup, if your camera asks you for the focal length, enter the actual focal length as labeled on the lens. This will ensure optimal Shake Reduction performance. For zooms, you can use the lower end of the zoom range (this ensures that there will be no over-compensation), or the focal length that you shoot at most often.

Now, let's discuss metering. Since manual lenses don't feed aperture data to the camera, the only way for the camera to check how much light is being passed through the lens is to measure the light while the lens is stopped down. Follow this procedure to properly meter with a screwmount, M, or K lens:

___0. Ensure that the "Using Aperture Ring" custom function is set to "2 (allowed)" (K-30/50/500/01 users must also ensure that the green button is configured to Tv Shift in M/TAv Mode) as described above
  1. Set your camera to M mode using the mode dial (your camera won't fire in other modes*)

  2. Compose and focus your image.

  3. Using the aperture ring (the ring at the very back of your lens; it will have numbers such as 2.8, 4, 5.6, 8 written on it), select your desired aperture setting. Note that the smaller the aperture number is, the more light passes through the lens, and the blurrier the out of focus areas of your photograph will be (and vice-versa). Note your lens will not stop down until step 5.

  4. [Screwmount lenses only] Switch the diaphragm clutch on your lens to "Manual" (you can leave it on Auto when composing and focusing if you don't want a dark viewfinder).

  5. Measure the light by either pressing the "Green Button" (older bodies may use the Av button), or pushing your power button to DOF preview mode (only available on high-end bodies). Your camera will automatically set the shutter speed for you.

All that's left now is for you to press the shutter release button to take your photo. Congratulations- you've now learned how to use M42 and M & K manual lenses with Pentax DSLRs!

*Screwmount lenses may also be used in Av mode since they are always stopped down to the aperture you will be shooting at (unlike M&K lenses, which are stopped down only when the shutter is released or when you meter as described above).

Note: if your aperture ring has an "A" on it, instead of doing stop-down metering as per this guide, you'll want to set the ring to "A" and use the camera's scrollweel to adjust the aperture via Av mode.
