As kypfer and clackers say- and indeed practice makes closer to perfect. Improving your panning skills is vary important. Developing a good quick eye and trigger finger as to just when to release the shutter takes time and experience. I also prefer the half press for fast action sports shooting, as my finger is constantly going on the half press and for me it is quicker to complete the press when my eye says "now" to fire the shutter, compared to using both thumb and front firing finger. For me, one finger beats two operating. What ever works best for you. In doing this to gain experience, you also become more aware of the fine points of the movements of the sport, which makes anticipating the action a bit easier.

I also have the older HD WR version, for many years now, and have hung on to it. AF has been good enough, and actually improved for speed and sureness noticeably with the KP! If you don't go to extremes from near to far distance back and forth, this also allows AF to be a lot quicker. It and the new PLM version each have their own advantages.

A main reasons for less AF speed in the old version is a longer rotation focus throw. But this can be an advantage when it comes to manual focus, including the quick-shift AF manual focus touchup. Having more rotation range allows for easier manual focus fine adjustment. The old manual focus lenses typically have more rotation range than is typical for AF lenses.

Another advantage for this older lens is in not being of internal focusing design, but has instead a standard focus mechanism. The internal focus technology can help with focus speed, but also tends to introduce what is called "focus breathing" which will shorten the effective focal length at shorter shooting distances. So if you say creep up to get fairly close to a bird or other small wildlife, and are say shooting at 300mm, the resultant size of that bird in your picture will be larger with your older lens than it would be with the newer one. If you'd be happy enough with the smaller size the new lens could provide at 300mm, with your older lens you could shoot at less than 300mm to get the same size, which should improve image quality. Zoom lenses tend to be not at their very best when racked all the way out.

The upgrades of this optical formula by adding HD coatings and WR construction were important upgrades. I used to have the previous version, which was slightly damaged but only to filter threads so filters could not be used. Upon getting the HD WR replacement, I was surprised to find improvement in image quality was noticeable due to the HD coatings! Better contrast and detail.

K-70 upgrade - K-1 Mark II or K-3 mark III?
Posted By mikesbike

I have both the 24mp excellent KP and now also the excellent K-1 II. The KP is great, even better than the K-70, yet even though I don't shoot with Sony, your friend is right in that my K-1 II is still better at higher ISO than is my exceptional KP.

That said, I think you'd be best off with the new K-3 III. The very useful DA 55-300mm PLM lens you have would not yield its full benefits on the K-1 II where you'd have to use it either not over its full zoom range, or in crop mode, where it would provide resolution comparable to an APS-C camera of about 16mp. Your former DA 18-135mm lens is likewise very useful and versatile, but as you said for your uses its aperture limitations were at times an issue, then the obvious choice would be the new DA* 16-50mm f/2.8 PLM lens. I have both a Sigma 17-50mm f/2.8 EX DC HSM lens for these needs, as well as the DA 18-135mm for general purpose. Unfortunately, that Sigma lens is no longer available for Pentax so you'd need to find a good one used. Maybe more of those will come up after the new Pentax DA* 16-50mm PLM has been available for a while. (for my K-1 II I have my very old but excellent Tokina 28-70mm f/2.6-2.8 ATX Pro II for similar framing to my APS-C Sigma 17-50mm f/2.8 lens, but delivering 36mp resolution, and the excellent DFA 28-105mm for general purpose, again able to deliver the superior 36mp resolution but doesn't have as much zoom range as my APS-C DA 18-135mm)

The new K-3 III is close to equal of the K-1 II for higher ISO performance. APS-C offers practical advantages in lighter carrying with better reach for telephoto needs, while the FF K-1 II will deliver superior resolution when comparing imaging using 2 different lenses of similar quality that provide the same framing on both it and the K-3 III when shooting from the same distance. That becomes more and more expensive and heavier, and less and less doable as you go more into telephoto (and is even true of a fast f/2.8 ultra-wide zoom lens). Of course this means having BOTH the K-1 II with the right lenses AND the K-3 III with a fine APS-C lens set, would be the most ideal situation. Then, once you should arrive at this enviable circumstance, you have to ask yourself- how often would you leave the heavier K-1 II behind and take the K-3 III instead, or the other way around?

Indeed, the K-3 III OVF is extra-fine. I have no experience with the Sony. But I know the exclusive Pentax Hyper System for one thing is important for me. Taking instant control when in "P" mode, and then for extra fast and efficient metering in "M" mode using the green button, spot metering in particular, is very special. I definitely concur regarding the added top knobs of the KP and K-1. Very clever and useful designing.

Nothing wrong with this- it is a truly great camera at a great price. And spot on since you already have some good FF lenses, so you can explore the advantages of digital FF. This fine camera with a top-quality Pentax APS-C outfit make a great team.

I have a number of old Pentax DSLR bodies I should sell as they just sit taking up space. I am just reluctant to bother taking the time to sell. I mainly am now using my KP and K-1 II. But I still sometimes use my little K-S2 which I bought for light-carrying casual use but very capable if an opportunity for more serious use comes up. I still use my K-5 IIs when I want its great set of on-body controls and features, and even power-zoom availability. I still like my old K20D for its colorful rendering in Fall scenes, etc. and very good for indoor flash also. The rest of my old DSLR bodies could go. I still have my once often-used film SLR bodies, which are rarely used- 2 MZ-S one black, one silver/black, 2 PZ-1P a great full-featured design and much like a modern DSLR, the very compact ZX-L that like the PZ-1P can take old M lenses as well as those with no aperture ring, without any adjustment just attach and fire away, and the classic designed ZX 5n, and the MF Super Program.

Yep, and you have a better system of controls and a very fine OVF. The KP is definitely THE APS-C DSLR alternative to high-end APS-C mirrorless and much more. There's another interesting thread about the "reach" afforded by APS-C being real also. For me, my K-1 II presents an advantage with shorter lenses, while 24 or 26mp APS-C with the same framing would not be quite up to the 36mp of the K-1 II. The APS-C is definitely more advantageous for lighter carrying with the 24 or 26mp still yielding plenty of resolution, as well as in the tele range.

Use of older flash units on Pentax K-70

If it is an old Pentax flash unit, even those with TTL capability, (recent models like the K-70 cannot function with TTL- only P-TTL or manual) if it has an auto mode as you say, which uses its own meter to regulate the flash duration, I have used such a flash with this setting on a modern DSLR, though not recently. Results were quite good for my uses. One of my favorites for on-camera use in this manner has been the AF 280T.

Great shot of such an elusive subject. Good sharpness in the closeup considering it is obviously cropped out of the scene. Which version of the 55-300mm are you using? It doesn't appear in the exif.

There were 3 versions of the Pentax telephoto 55-300mm. There was a DA-L 55-300mm kit lens, the least expensive, then there was the DA 55-300mm having a better build quality and quick-shift manual focus touchup available for AF shots, and then finally the HD (High Definition coatings) DA 55-300mm WR version. All have the same optical formula with f/4-5.8 maximum aperture, and operate via the camera's screw-driven AF system, which exhibits a slight noise.

The new PLM version is more compact and has its own silent and faster-focusing motor, but in a more compact design while that smaller size comes with a maximum aperture of f/4.5-6.3 which is somewhat smaller than the older versions, letting in less light.

Me too. And great stuff, Norm! I think it fair to rank below 10 a lens that is less than absolutely perfect, but which can still enjoy a very high score. I am ok with that and see such a lens as very fine indeed. Then there is still some room for that very rare lens that bumps up against being very near absolutely perfect.

Maybe someone who gave a very uncharacteristic low rating simply got a bad copy. Or maybe they simply have a lot yet to learn about how to use their equipment. So taking these matters into consideration when dealing with such a minority opinion makes sense.

Lenses for K-3 III for indoor sport

Well, sometimes the older SDM AF system fails altogether. When this happens, the choice with most of these older SDM lenses is to either have the SDM repaired (with the chance it could fail again) or to have it converted to the old alternative camera body screw-driven AF system, which is noisier. Not all of these older SDM lenses are candidates for this option. Some of the newer lenses having the "SDM" designation are actually of a different design which is not subject to this problem. Other newer AF lenses are either designed with DC motors, the newest PLM system, or still using the old reliable screw-driven technology, and that does not mean they are cheap. All of the Pentax elite "Limited" prime lens series are still made using the old screw-driven AF system. The only Limited lens that is a zoom lens, the DA 20-40mm Ltd, also features a quiet and very good DC AF motor as well as WR construction.

The screw-driven AF technology is a very old camera-body based system instead of the lens having its own AF motor, which came later. A good lens-based AF motor will provide quiet, less distracting but superior functionality, with greater possible AF speed and accuracy. Yet depending on the lens and camera model, many lenses designed with the now ancient camera body based screw-driven AF system are still capable of excellent AF speed and accuracy, albeit with some noise.

Lenses for K-3 III for indoor sport

Since you know already what the DA* 50-135mm can do for you in terms of framing, and the AF speed is your main issue, the K-3 III is designed to be faster and more accurate for AF during burst shooting. But with these older SDM lenses, the question of improved AF speed remains an open one, since this AF technology might be the limiting factor. It has been reported that AF speed with these lenses is improved upon conversion to screw-driven AF. This is such a good lens, it is a shame that it has been neglected for an HD upgrade with at least a fast DC AF motor.

No doubt you've noticed AF from your DA 18-135mm WR DC is quicker than that of your DA* 50-135mm. I've found its AF to be reliably fast and sure (but with its aperture limitations it needs more light). I have both and that is my impression. As far as AF overall is concerned, the K-3 III has a moe advanced system over the K-70. My KP has in fact shown quicker and more sure AF even with screw-driven lenses compared to the same lenses on my K-S2 or my K-5 IIs.

Looks like you got a great buy for a great camera! No comparison from those Canon and Nikon models. Now she and you have a durable camera body made to professional standards with its build quality, features, and dedicated on-body controls. A good APS-C partner with your K-1.

I would recommend consideration for the Pentax AF 201 FG WR super-compact flash. It is inexpensive yet has more power than any built-in flash and even has a tilt head for bounce. I've found it to be very handy for my K-1 II, or even when I might need a bit more flash capability for my KP but still want compact carrying.

I love mine, have had it for some years now after buying it new. Not wanting the size and weight of the DFA 70-200mm f/2.8, I instead opted for the DA* 50-135mm plus the DA* 200mm f/2.8 so at no time having to have a very large and very weighty 4 lb. lens on camera. For me this concept works very well. Of course I was then shooting only APS-C, and this was before the arrival of the K-1, but I still reasoned if FF came and I went for it, I would likely be using shorter lenses on it anyway and reserve tele shooting for APS-C. And now that I have both my KP and K-1 II, that is indeed the case.

Since this DA* lens is actually a FF design, if I should ever want a quality 200mm tele shot from my K-1 II and/or its f/2.8 aperture, It will still be there and capable, yet still compact for the purpose. I still have not done so, but I have no doubt it would provide very fine results. I could also use my old Tamron AF 1.4x TC with it if I need more reach without adding significant size.

The DA 16-85mm is also an excellent choice, though I've seen more reports of getting a substandard copy and needing to exchange than with the DA 18-135mm. It is also heavier and bulkier, as well as costlier. If you get a good one it is an exceptionally fine lens.

It is an excellent choice for this kind of use. Amazingly compact for such a wide zoom range, and for less need for lens-changing yet with high quality results. Wonderful on my K-5 IIs. If you look through he offerings in that thread in the lens section, "DA 18-135mm WR Show us what it can do" and start with the last page (most recent) and work backwards, often the camera model is also given. Of course there are good and not so good photos taken with the best equipment, but among the results you can find good examples that will demonstrate differences in imaging, resolution, etc. from the camera models also. That is how good this lens is. It can even deliver very good closeups.

Yes, this seems to be sometimes an issue in designing faster focus for AF vs. a good precise touch-up focus for manual focus. The shorter throw can be better for faster AF but not so good for precision manual focus.

That's a good one- you're fine. You might still possibly consider that DA 18-135mm all-arounder at some point due to versatility, great AF, and it has WR construction like your camera. It is also far lighter than your Tamron 28-75mm for carrying when you don't need that f/2.8 aperture. It can keep to f/3.5-4..5 out to 70mm. With Nikon or Canon, for instance, you cannot shop new cameras that have WR construction until getting into at least the $1,000 USD range on up while Pentax now has it through the entire lineup. Shopping new lenses with those other brands will likewise be $1,000 up for WR. A camera cannot be actually WR unless having a WR lens on it.

As to telephoto, with the K-5 IIs, there is the HD 55-300mm f/4-5.8 ED WR, which I have and like very much- and still available new, and with a K-3 or later model there is the later HD 55-300mm f/4.5-6.3 ED WR which is one of the few having the new and extra-fast PLM AF. I still hang happily with my older one, as its old reliable screw-driven AF is good enough for my needs, and image quality is close between them. They are both bargain lenses for what they bring.

Very good lenses. However, except for the two DA 35 and 50mm, the other three were designed for 35mm film or full frame (FF) DSLR use, the two zoom lenses being able to provide a wide angle FOV, but when used on APS-C camera bodies, none of your lenses will provide any wide angle at all.

I agree. The AF performance was upgraded over the original k-5, in addition to its other upgrades.

As to an all-around lens, the DA 18-135mm WR lens on this camera as well as on any other model, will deliver the same fast, accurate and quiet AF while providing fine performance. It is also amazingly compact and well-made for its wide zoom range. I have a number of other alternative lenses, some with more aperture, but of less zoom range, yet this lens is still my go-to when I need its versatility, and I have no worries about its quality. Some have experienced the development of zoom creep. Even after 10 years, I don't have this issue. But I never carry my cameras loose hanging down on a strap. Instead, I use a belt-loop holster case also having the across-shoulder strap as well for stability, weight distribution, and security. I then have instant access when needed, then return the camera to the case after taking my shots. You should eventually be able to find a good used DA 18-135mm at reasonable cost. You can see examples taken with this lens and perhaps some even with the K-5 IIs, in the SLR Lens section under the thread- "DA 18-135mm WR Show us what it can do". Start with the last page, which is the most recent and work backward. One thing at a time, of course. If your need is for a shorter fast-aperture zoom lens, the Sigma 17-50mm f/2.8 EX DC HSM is my recommendation.
