Maoby: Nothing very exciting, when will Pentax release some real news?

I'd love to see a new MF Pentax, I miss the years 2010-2012 …

Pentax 645D (2010) / Pentax K-01 (2012)

Thanks anyway 🙄

645 line is dead, deal with it. There will be no more cameras or lenses.

thx1138: So like f/30 FF equivalent lens, perfect for the low light aquatic environment.

There is no "standard reference FF sensor" and comparisons do not work also. There is huge difference of noise and DR characteristics between modern 24Mpix FF and modern 60Mpix FF. The only interesting value is pixel density which correlates with size of photosites. The smaller they are, the worse output you can expect. For example 60Mpix FF sensors have basically same noise and diffraction issues like 24Mpix APS-C sensors or 16Mpix M4/3 sensors, also similar dynamic range. Remember how Canon EOS 5Ds bodies with 50Mpix struggled heavily at ISO1600 and above while being FF with that magical "large amount of light collected by large sensor" and how for example 16Mpix Pentax K5 ruled the DXO sensor ratings for some time thanks to great HI-ISO characteristics although being just APS-C.

There is no universal formula to say something stupid like "oh that is like f/30 FF or oh that is like ISO4500 on FF".

It always depends on sensor technology, generation, resolution per area and lens used.

OMG this nonsense again. There is no F stop recalculation for exposure or "light hitting the sensor". It is light per area and it is identical no matter what piece of image circle you crop. When you take photo with film camera and cut the film into smaller piece, does it change exposure? No of course. Stop spreading that like kids.

But F3.5–5.5 lens paired with 1/2.33" hi res sensor means, that sensor photosites are tiny, there is quite a lot noise and lens is not fast/bright enough, to use low ISO values anywhere but on good daylight. I expect this camera to operate at ISO400-1600 a lot, which affects image output a lot. Lot of noise, minimum dynamic range.. and also details destroyed by diffraction.

Some larger 1/1.7" sensor with 12Mpix and F2-F2.8 lens would be much better..

Finally some interesting FF lens.. just the price level is devastating :D

M for Mobility: The Canon M system should be on the UNESCO world heritage list. 😉

It's unique.

Is not, just one of many lost Canons.. they just threw it away like whole FL mount or EOS mount recently.

It was design failure right from the beginning. Poor those who invested into such system.

xmeda: It will be nice to reincarnate XZ-/XZ-2 series and prepare some XZ-3 with modernised sensor, better AF, wifi etc..

Or Stylus 1 series :)

No need for phone calls, but modern users will require some quick transfer to Instagram, Facebook, Twitter, Tiktok and similar services.. like just play > send to phone > 2s and file is in phone. Then it will do the job. Then you can take pic of some bird, musicans on distant stage, portraits or plane on the sky or other things and put it on social media. But on the other hand you'll still have good RAW on card for regular processing.

Also add USB-C charging in camera, hi-res stack mode, some nice 10+fps mode, at least 3mil dot EVF and keep the sensor resolution in usable level to avoid noise issues.

It is also about marketing style. Even the older Stylus 1 absolutely wrecks most phones in general photography. Phones usually only can match it with main camera on the wide angle and on good light. But that 28-300/2.8 lens is different world. But the will need to implement phone connection, good control app and some instant sharing options Even Stylus 1s can do some wifi tricks and send pics to phone or be controlled by phone remotely, but it is lagging, transfers take time, connection take time.. just make this much faster and it will be excellent travell camera again in modern age with instant image transfers to phone.

Suntan: "Train" subject detection?

Does anyone really need the camera to be able to subject detect, and track, a train?

I haven't done a lot of train photography, but when I have, tracking those little buggers had always seemed manageable without a dedicated focus algorithm for it.

What's next? Building subject detection?

Even building movement tracking can be useful. During demolitions for example :D

Having no IBIS in 2023 is strange at least. It should be basic standard for every camera designed in last 10+ years without any debate.

For example every Pentax DSLR has IBIS since 2006 as standard (with one exception K110D sold in very low numbers in 2006).

Design of this body is almost perfect. Removable EVF is great. Of course two rollers and joystick. Lens release button is in correct spot. Multiple programmable buttons are perfect. Top status LCD is excellent here. And large LCD is articulating. Bravo! This should be standard from now for everybody.

There are only two big issues. It does not have K mount and some nice APS-C sensor. :D

In reply to:

Digmen1: If Nikon made a DX camera with IBIS and a couple more lenses, that would show they were serious about DX.
I have heard vloggers say that mirrorless cameras need IBIS for steady vlogging.
But of course the camera would then be bigger, heavier and more expensive.

Nope, there are smaller cameras that do have IBIS.

No IBIS no interest. Easy.

In reply to:

mrphotoguy: (part 1)
I've read a lot of comments here and it seems that people like to complain about a few things.
1) Canon cut corners
2) Canon didn't include IBIS
3) Some other camera maker makes a better camera
4) You have to have a better camera to take good pictures nowadays (my favorite)

Whatever camera manufactured since 2006 should have IBIS as standard. Period.

Just some manufacturers are still trying to cri-pple some cameras by reduced functionality on purpose to push customers to hi-end models. Which is disgusting.

Good news! :)

It will be nice to have modern film SLR capable of working with new Pentax lenses like DFA*85/1.4 with modern metering, autofocus etc, but such camera will be $2000 and without customers.

And Im afraid that even a bit cheaper compact film camera will struggle a lot with customers. But with Ricoh, we are getting used to that..

In reply to:

4Photos: This would have been great news 10 years ago, when there were hardly any lenses available for the A7,.... but today?

It is not "another option for Sony users" it is lifesaving hack for Pentax users who need some modern camera.

Still no 3rd party lens support in 05/2023 :(
