Pentax K-1 wiping the floor with Nikon D810, D850.

Yeah I can't attribute it to the camera for sure. I don't have a lens that crosses over to both cameras obviously. I will say though that i've used 3 lenses on the nikon and 3 on the pentax and the preference remains the same across all of those lenses. I'd guess it has more to do with the camera than the lenses but I don't know. The interesting thing to me is that the D850 doesn't impress me above and beyond the K-1 with anything except autofocus ability. Maybe that will change as I get more familiar.

I got the D850 specifically for the increased AF performance. I have still not sold my K-1 (after a few failed attempts) so I have both cameras right now. I'm testing some things out. All in all, I really can not tell a difference between image quality and detail in real world scenarios.

I will say that the D850 locks focus with more leeway than the K-1, but does it a bit faster. I have yet to get an image that's not exceedingly sharp on the K-1 when it say's its in focus and the subject isn't moving. The D850 is always "acceptably sharp" and this is even after doing extensive AF fine tuning to find the right number for the focal length. When things are moving it's a totally different story and i'm really happy I have the D850 now for the type of shooting I want to do (sports events, weddings, etc). Also the low light focus is just waaaay better on the D850 vs the K-1.

Generally, I prefer the images that I get from the K-1 vs the D850 when it comes to colors and general "feel". Such is life. I think there's still a lot of legs to stand on for the K-1. It's just not THE BEST choice for action photographers.

Then the question is, what's the path to getting more bodies sold. They're already the cheapest option while still having an amazing product.

Just having more options even if they overlap would modify the ecosystem, particularly the prices on used lenses. There are also lots of people who seem to really get into specialty lenses and are willing to spend lots of money on many of the same types of lenses. Pentax won't make money on the third party lenses but they could grow their user base overall by doing this especially in concert with the K-1. It's really unfortunate that their relationships with third party lens manufacturers seemed to have fallen apart right as the K-1 came out. We'll never know just how much business they lost from that. Generally I think people would love to move to pentax based on their philosophy as long as they could check off all the boxes in their head about what they require (and at least for me it's the two things listed above).

Work on AF. Convince tamron and sigma to continue making lenses for pentax. I'd be a lifer at that point.

K1 Autofocus

I'll mirror most everyone's response here and say the K-1 is pretty good for static subjects. In fact i think it's typically more accurate once it locks as compared to my previous setup (Nikon DF).

For action photography it's a crapshoot. It seems to do ok with left to right motion, but anything coming towards you or moving away causes it to struggle. Still though i've been able to get in focus shots maybe 1/6 or so with those sorts of circumstances.

I think it's honestly a perfect camera unless your main style of photography involves lots of motion.

I just sold one for 1450 on the marketplace. Sad to leave pentax but I've really started to focus on event photography (bicycling, running, etc) and weddings. AF is really accurate and good but it's not SUPER quick. If i was still doing portraiture and landscapes there wouldn't have been a reason to leave. The camera is ridiculously cheap for what it offers.

For each Pentaxian buying K-1 another Nikon/Canon shooter jumped ship to Pentax

I'm one of the Nikon converts. Nikon was really starting to annoy me by disabling features on cameras just to position them in their line up. As an example, look at what they did recently with the D7500 by removing a second card slot (compared to the D7200). This is clearly just to ensure that pro's need to buy the D500 even if they don't need the D500.

Pentax seems very much like the company that is dying to give the customer everything they can for the lowest price possible. I want to be part of an ecosystem where people are scrappy and care deeply about what they're making. Nikon seems like they're pretty damn far from that at this point.

I really do love pentax. I do think though that they really need to focus on two things to continue with the momentum of growth and to keep current converts happy. The first is to somehow convince tamron and sigma to continue making lenses for pentax. What tamron and sigma have been doing with their lenses recently is amazing and it does sort of feel like we're missing out. I'd love to be able to get the sigma 85mm art on my K-1. The second thing I think they need to do is improve autofocus speed so that these cameras can be depended on to shoot action/sports. Do something like what Nikon has some with the D500 and add a dedicated processor for autofocus.

I know the pentax community is very tight-knit and many of us are people who come directly from film or are at least "old school." The response to criticisms of pentax seems to basically be "when I was a kid, I had to walk both ways uphill to school in the snow." It's not helpful and it will fly less and less as more converts come to pentax. I would imagine the only way pentax stays alive is for them to find a strong and compelling reason for people to move over to pentax and to stay. The K-1 went a LONG way towards making this reality. I think they need to continue to push. I don't think their full-frame lens line-up that they've promised is enough.

I'd also agree. It tends to be spot on once it locks. Since starting discussion in this thread i've looked a bit closer at the settings. I think release priority would be preferable at a wedding since it seems to get close to good focus and then fine adjust itself. Next time I shoot one I'm gonna play around with the focus settings a bit more.

You can set up trap focus as well. You basically hold the shutter button down and when the camera determines the middle focus point is on target the camera will automatically shoot. I've used it with an old 50mm macro and it works pretty darn well.

Shooting my first wedding

I'm generally comparing it to how my Nikon DF performed previously. Not much different in the way I shot this wedding. I do try and find high contrast areas to lock focus on and then recompose.

I found that the K-1 was slower than the DF by a large margin, though when it locked on it was more accurate than the DF was. What I've truly found to be difficult for the K-1 is subjects which are moving towards or away from the camera. It really seems to struggle. I'd love it if I was simply doing something wrong obviously but I don't think that's the case.

I second-shot a wedding with the k-1, the pentax 24-70, and the metz 52 flash. The images that came out were great, but keep in mind non-pentax flashes will not trigger the AF assist lamp and the K-1 has a really hard time finding focus on anything that's moving, especially when it's dimly lit. Dance photos will be very difficult. Anything in the church will be hard. I wouldn't even attempt AF-C while people are walking down the aisle. I had multiple times where I literally held the shutter down for 4 seconds while it was attempting to find focus.

I really do wish pentax would improve their AF speed. It does seems to be very on point whenever it locks on though which is good.

I wouldn't really recommend the k-1 as a wedding camera.

Thanks again everyone for the answers. I ended up grabbing a tamron off craigslist yesterday for 600. Its pretty dang sharp and the autofocus nails it almost 100% of the time. Attaching a shot I took this morning, first is the full shot, second is cropped in.

Thanks for the responses everyone. I do know the 55-300 is not FF, but i'm wondering if it's that kind of non-FF that has minimum to marginal vignetting but otherwise works well? I have the DA 50 1.8 and that is pretty decent on FF.

Hi Everyone!

I'm looking to make the complete switch over from nikon to pentax. I've purchased the K-1 and the 24-70 2.8 and I love the combo. I currently have the nikon 70-200 f4 which is an amazing lens (sharp as a tack, super fast and accurate autofocus). I'm planning to sell it and buy a pentax lens which covers the telephoto range.

I have my eyes on the tamron 70-200 f2.8. It seems from online reviews that it's pretty sharp. I am concerned about autofocus accuracy and speed.

The 55-300 WR RE seems to have autofocus covered pretty well since it uses the new pulse drive system, but i'm wondering how sharp it is when compared to something like the tamron.

I don't care about the difference in aperture, but when it comes to AF and sharpness can anyone provide some comparative analysis or opinions? Thanks everyone!

-Lars

I ended up keeping the Metz. I've just accepted that I'll have slower focus speed and will adjust accordingly.

I'm really loving the K-1 and the autofocus is pretty darn good in good lighting conditions (tending to favor accuracy over speed which I like). I am however facing issues finding a way to auto-focus in lower light situations. This is really important for wedding photography and event photography (both things I do).

I started off my quest for good low light auto focus by renting the Amazon.com : Pentax AF540FGZ II Flash for Pentax DSLR Cameras : On Camera Shoe Mount Flashes : Camera & Photo. While the flash itself worked wonderfully, I found that under many circumstances the autofocus took .5 to 2 seconds to lock on. This was in sub-optimal lighting conditions but with people posing just a few feet in front of me, nothing that should be too difficult with an af assist beam. My intuition was that the af beam on the 540 wasn't that great, or that the camera itself was not turning the af assist beam on under circumstances when it thought it could manage. I did see the af assist beam come on from time to time but not always.

Suspecting that perhaps the 540 af beam wasnt that great I ended up purchasing the metz 52 af-1. I then found out that the af assist beam simply doesnt work in concert with the k-1. It's fully incompatible. This leaves me with the built in AF illuminator.

Comparing to my nikon d3100 plus the sb-700 (pretty basic flash) the difference is literally night and day (pun intended) and the nikon d3100 is a pretty basic camera.

I am concerned that there is simply something wrong with the k-1's algorithm for enabling the af assist beam ...

Has anyone else had better results than me and under what circumstances?

Thanks!

-Lars

[Update] - I always set the camera to spot focus (center spot) and use AF-S.

You should be aware of the fact that the K-1 does not use the Flash's AF beam for metz flashes (and i think any other third party flash). I ordered a Metz 52 af-1 thinking it's the best deal for the money but its pretty disappointing that the af beam is useless, especially since I want to use the k-1 for weddings where I need AF assistance in low light. I am considering returning it right now.
