I've enjoyed reading this thread, especially the lens discussions. To be honest, one of the things that has put me off upgrading to a K-1 is the amount I would have to invest in glass to get the most from it. I have some really nice lenses for my crop sensor cameras that I know and love, they work reliably for what I want / need them to do. I don't think I could do without a F2.8 zoom, or indeed my DA*300 F4, so to get similar performance on a K-1 I would be spending thousands.

+1 on this. I'd love a K-1 for sure, but at the same time I acknowledge that it's not really the camera for me. The K-3 has solved nearly all my issues coming from the K-30/K-S1 lines, in terms of burst speed and control over AF tracking and behaviour. Taking photos of the kids in sports/triathlon type situations, and birds, has just been a joy compared to the frustration I was experiencing previously on this subject matter. The K-1 isn't a K-3 in FF in these regards.

And I too have mostly DA lenses, so I'd have to seriously consider the implications of moving to a new lens range, as that's just as important (if not more) than the choice of body.

The K-1 seems tailored as a landscape/stills camera primarily, and I would expect a K1 mkii to improve on the areas above, to bring it more in line with the speed aspects of the K-3 range.

Side note re gig photography, I totally get where you are coming from. There are times where adding your own light via flash etc is not an option, and you have to be dynamic to work with the situation. Opening the shutter longer to gather more light isn't an option either due to subject movement, so you have to maintain the shutter speed. Really leaves ISO and Aperture to play with, and sometimes you want a deeper depth of field too (especially as too narrow a depth of field requires the focusing to be spot on, and in low light...).

The above is actually the exact same situation for video, where typically you aim to keep the shutter speed relevant to your frame rate. The solution here is a targeted specialist body, where the sensor is engineered to work better in very low light, so much so that you'll probably need ND filters to use at normal daylight levels. Examples from other brands would be the Sony A7s and Panasonics GH5s products, which are intended for this niche situation.

I can't see the K-1 being targeted into this direction specifically, as other brands have released this as a side offering away from the main product.

I would be more than happy with a set of lower priced f4 lenses for the K-1. I doubt very much it will happen but a 16-35mm, 24-70mm, 70-200mm f4 setup would suit me perfectly. Canon's versions of these lenses are sharp wide open and relatively cheap when compared to their 2.8 offerings.

ah yes! a 16-35mm f4 lens will be perfect...the inability of the 15-30 to take my Lee Filters is a bit of an irritation (yet I don't take the SA12-24 out that often )

If it helps you to decide, the DA* 300mm f4 is a full frame design. Works beautifully on the K1. No vignetting.

Ah, OK didn't realise the DA*300 was full frame! I bet it is stellar on a K-1 isn't it? The 50-135 wouldn't be any good though would it? Anyway, if you've read the 'SDM failure' thread which includes reference to focusing issues with my 50-135 at wide apertures, I suspect this problem might be worse on a K-1 than it is o a K-3 due to even less DOF.

To be honest I have not given the 300 a good run for it's money yet on the K-1, that will be my task this year. The K-1 honours lens corrections for the DA*300 and DA*200 in both FF and crop mode

Not sure about the 50-135. You should check over at Pentax Forums as they have a dedicated compatibility thread. The DA16-50 did not work and I sold that. The 60-250 works very well for me. Some have resorted to a "baffle modification" to remove vignetting completely, but I don't feel the need. it is not drastic for the kind of shooting I have been doing with it. The DA 40mm and DA70mm worked fine too. They are both prone to minor vignetting which can easily be resolved in post if you are not cropping the picture

Interesting you mention DOF. There have been a tonne of threads on other forums about the change in DOF when moving to FF versus crop sensor. Personally I dont notice it. When i want a picture with a certain amount of DOF I just fiddle with the aperture until i get what I want. Maybe I am just unobservant

But I did say 1/250th of a second, not 1/25th!

Hi Darkskies, Apologies, I can see you have mentioned 1/250 in a few places, but the bit I read was one of your replies about 2/3 down page 2, which does say 1/25 secs, see text below:

Firstly, the artists are moving. Bit of a bugger, I know, but it does mean that a minimum shutter speed to freeze the movement is required. Although this can be reduced for the less-lively performers, a shutter speed of 1/25 secs gives you a reasonable chance of getting sharp images, although if there are multiple performers all doing their thing, even that can be difficult. Take quite a few shots, get a few keepers. Nobody mentioned shutter speed, but at gigs it's most important.

Regardless, I think we agree, but we have hijacked the original point of the thread i think! Apologies to anyone who isn't interested in gig photography or what shutter speeds we need to use!

Regards
David

lol! Mistyped!

The thread was derailed by a question, which seems to have been answered!

We seem to have laid out some maximum ISO limits for the K1 .... For example, I'm taking from from it that for high quality low light shots that could be used professionally, the limit is ISO 6400.

Should we be hoping for an extra stop of ISO performance from the K1 MKII sensor ?

There are test shots at each ISO setting here: https://www.ephotozine.com/article/pentax-k-1-expert-review-28884/performance - if we download the High Res images then we can see for ourselves where the quality gives up.

Having said that, in extremis and with an important enough image then any ISO can do and make a successful image. Or the noise can be used creatively.
Best regards, John

For sure John. I have been surprised here by how high the bar is being set and how apparently conservative the attitude to these real life limits I do think that each individuals capacity (both skill set and availability of software) for noise reduction processing will have a bearing. Not all will be equal here.

I'd agree that you can use the noise creatively, if that's what you want. Also, different people will have different ideas on what is a high enough image quality for them.

I don't think you should be surprised, though, that when you are taking photos in a professional environment, or when you may be in competition with other photographers for business, or even if you want to print big, then image quality, as well as creativity, is in high demand.

It's horses for courses, really.

I also don't think ISO 6400 is the maximum for a K-1, even with those things above in mind. I've got good ones at ISO8000, but I'd admit that this seems more hit and miss. 6400 is eminently usable for high quality gig images.

pentaxrumors.com have posted details of the new hand held pixelshift which sounds like it came from Ricoh although they do not quote a source.

https://pentaxrumors.com/2018/02/20/the-upcoming-pentax-k-1-mark-ii-dslr-camera-...

I find it hard to believe that Ricoh would post details of a camera that only exists as a rumour. They would surely launch the camera first or at least confirm it's being released.

Itís not April 1st is it? Camera supposed to use SR to work pixel shift whilst hand-held using the tiny movements generated. So does that mean SR doesnít do what it is supposed to?

At present SR can't be used with pixel shift because the camera has to control all the movement 1 pixel at a time. The new system, which may well only work for hand held with SR turned on gets the shots by grabbing them from the sensor as it moves. Bit like jumping off a bus before it stops. It will have to be done fast.

I assume it will revert to the original method once SR is turned off.

Pixel shift is amazing It puts Pentax well in front of everyone else
Look at these shots of flowers by a photographer whose work I've admired since the *ist DS days. He used to use a lot of old M series lenses in those days and got some great stuff.

I have had a K-1 since launch and used pixel shift just twice. How about you?

I've used it a few times on landscapes when there is no obvious movement in the scene and compared the results with non pixelshifted images. My conclusion was that, at least in my (big vista) samples, the main differences were due to small movements in leaves & foliage and that the impact in other areas was not really significant for the image as a whole.

I haven't yet tried Pixelshift indoors where I would expect to see more of an effect.

BTW I have found that the best tool for examining PS images is Rawtherapee, which enables one to play with the individual images of a PS shot.
