Alternative Crop Mode for APS-C lenses on K-1: Square Images

Do you have a source for that?

We can see in the video npc posted on the first page that there was a 1:1 mode on preproduction models, and I still maintain that since the whole finder goes dark and blurry when you remove the battery there is a display covering the whole thing.

I took a photo through the finder that I think shows at least that the crop frame and the grid are not really the same display. (This is the lower right of the crop frame, showing the grid line in focus but the crop frame not so much.)

K-1 Sensor Dust

There is probably some difference in what people mean by "cleaning the sensor" here. When I said I had cleaned my K-1 sensor once I meant with air. This is the normal cleaning method in my mind. I may have wet cleaned the K-5, but I don't think so. I have wet cleaned the K20, and I have wet cleaned my stupid Canon 5D2 several times. But anything that requires the shutter to be open is "cleaning the sensor" to me, and if you actually touch something to the sensor that deserves special mention.

But that's just me, other people will (clearly) have commented under different assumptions.

K-1 Sensor Dust

For equivalent pictures you'd be stopping down more on the K-1. Visibility of sensor dust is mostly related to the selected aperture (and thickness of the sensor filter stack, which is likely the same on all these cameras), so it seems reasonable to be more sensitive on the K-1. (Even though the size of the dust is a smaller part of the image, it's often too big anyway.)

I noticed this quite a lot when I used my Q more. I could have dust that was even visible to the naked eye on the sensor and still not see any problem in my images.

That said, I think I've cleaned my sensor once on my K-1, in about 2000 shots, which seems to be about the same as on my K-5.

With just the power off I see whatever I have selected to see. With the battery out, so the camera really is without power, I see nothing. Actually I see a hint of something right in the middle, smaller than the circle displayed on the LCD. But no trace of the lines are visible to me when the camera is without battery.

When I put the battery back in (without turning the camera on) the LCD clears, and no lines are visible. The thing in the middle gets a little easier to see though. When I turn the camera on the lines I have selected re-appear, and stay there if I turn it off again, until I take the battery out.

I can see this image (and the similar image on page 17 of the manual) shows no such provisions. I still think the hardware is not limited to this, because if it was this is what I would see when I take the battery out. What I actually see is the whole finder darkening. Why would that be if the hardware was limited to what they currently document?

Given that the whole finder goes uniformly darker when you take the battery out I think it's reasonable to think that the hardware can put whatever frames the firmware wants in the finder.

As I said in my original post, I have decided what it should change by selecting what the green button changes. (Shutter speed in my case.) There is no reason the camera couldn't follow this. The only reason it doesn't work is that the firmware has not been fixed to make it work.

This is not a regression from previous models, which have the same problem. But it's a problem none the less. Here's a simple step by step instruction:

1. Set the camera to manual mode.
2. Set some exposure that gives you the image brightness you desire.
3. Press AE-L.
4. Adjust the ISO.

Expected result:
Image brightness is maintained, as I clearly requested in step 3. Preferably this would be achieved by adjusting whatever I have set the green button to adjust, but honestly just working at all would be great.

Actual result:
Image brightness is changed, because only the ISO is adjusted. Just like if I didn't activate AE-L.

Note that if you replace step 4 with adjusting the aperture or shutter speed the result is as expected, the image brightness is maintained. I mention this because otherwise I expect someone to claim that the image brightness should change, because they ignore my step 3.

It doesn't matter if I adjust the ISO using the ISO button + back wheel or using the third wheel.

The thread is quite long, so maybe someone already said this and I missed it, but here goes anyway:

Another potential advantage of removing the mechanical parts of the mount is making it easier to have a fully working Q adapter.

Granted they skipped focus support in the existing adapter, but that might be because most of their current lenses draw more current than the Q can provide. This lens should take very little power to focus, and that's probably the direction they are moving. So a cheap (to produce at least) full function adapter should be possible. Right?

Of course I'm talking about what we have lost to the crippled mount. Or specifically I'm talking about what the MZ-S does, to hopefully prove to those who believe it impossible that it is in fact possible. Not on current cameras, obviously, but on future cameras if Pentax so chooses.

It would also be possible to provide this for A lenses, and if you ask about widest aperture on startup for K/M lenses, but no Pentax camera has done so yet.

I'm not going down the rabbit hole of debating the merits of this again. All I'm trying to achieve here is that people know what it is they say they don't (or do) want.



Are zoom and focus rings also impossible to use without looking at the rings? I think most people could operate a lens aperture ring easily without looking at it.

Also, in case it matters to anyone, my use of the word instantaneous referred to seeing the aperture in the finder, not the operation of the ring as such. "When the aperture ring is turned, the display in the OVF is instantaneously updated to show the newly selected aperture." (This is as opposed to waiting for you to press a button or something like that.)

I am saying that you can have both. The important and in fact only point is that setting the aperture using the aperture ring on the lens can still show the selected aperture in the OVF (and EXIF).

That's an implementation detail. What I never understood is why they choose not to support it on A lenses, since all the information required is in fact available from A lenses too (just in a different format).

(Yes, I know, the 50/1.2 doesn't provide that information. That's no reason to not support it on any A lens.)

It's not so much that I miss your point, but that your preference is yours and not something I need to comment on. Of course some people prefer to use controls on the camera, nothing wrong with that. And not really worth commenting on. ("You like that, but I like this, let's fight!" is rather useless.)

But the way you wrote it implies that you think using the aperture ring means not seeing the selected aperture in the finder, or at the very least others may well read your text that way. I don't want people to think that this incorrect inconvenience is how it would have to be.

So let me be super clear: "instant feedback in the viewfinder of any changes" (your words) is something I want when using the aperture ring. And at all other times too of course. And I don't want anyone to think that it wouldn't be possible.

I know I shouldn't, but I just have to answer this:

One of the reasons I (we) want an aperture feeler is so the selected aperture can be displayed in the viewfinder (when set from the aperture ring).

Anyone who wants to claim that this wouldn't be possible should also explain what has changed since the MZ-S, where it is possible and works fine. (It only works with F and newer lenses though. I have never understood why it doesn't work with A lenses.)

I find this completely unconvincing. If they can weather seal focus and zoom rings they can weather seal aperture rings as well. There's just no difference. (Click stops are on the inside, so that's not a difference. Being right up against the mount should be no problem, and if it is they can add as much space as they need before the ring.)

I'm sure many people are quite interested in paying less, but it's not the only reason to want old lenses. There aren't all that many options for nice manual focus lenses that aren't old. I have one Samyang and two "Zeiss" (Cosina), and they are fine lenses, but so are a lot of the old lenses. And many old lenses don't have any modern replacements, especially not in K mount land.

I can't argue that they get any money directly from people buying old lenses, but I can and will argue that it's still good for the brand. I certainly wouldn't be here without some support for old lenses, limited as it is.

No useful difference. You still have to set your desired aperture using the aperture ring on those lenses, it's just that the camera has a feeler for where you set it. Pentax could do the same for K/M lenses, they just don't.



I've never had a Nikon, but I think it's about like this:

Really old Nikon lenses are like most M42 lenses, they have no communication of aperture selection to the camera.
Newer non-AI lenses have a "claw" that communicates selected aperture, but it seems to require some extra gymnastics when mounting. (This is not supported on the Df, so they work like the really old lenses.)
AI lenses are like K/M lenses and tell the camera the relative aperture selected.
AI-S are like A lenses and can have the aperture selection controlled by the camera.

All versions of course have at least open/close aperture control from the camera, just like all versions of K mount.

It is apparently little known, but all reasonably high end Nikon bodies (D7000 and newer versions of the same, anything "pro", anything FF) have support for the Nikon equivalent of K and M lenses. What the Df adds is support for their equivalent of M42 lenses.

And I mean full support. Take an AI lens lens (like a K lens) and put it on a D7000. Tell the camera what the largest aperture of the lens is. You get aperture readout in the finder. You get working metering. Even flash metering works.



Notes 1 and 2 are only about the helicoid extension tube, which doesn't pass anything at all through (it's like those really cheap chinese K mount extension tubes, except it's a helicoid and not crap). No camera could to better with a tube like that.

Note 3 is presumably the same as for the 645N, which means it works fine for most lenses and some lenses are off half a stop. It's fine, I only have one lens with this problem, and it's not much of a problem.

I think they should have added the ability the tell the camera the largest aperture of 67 lenses, which would have made them work as well as the A lenses in non-A mode. (They give the camera the same information an M lens gives a K mount camera.) But it's still good. Much better than I dare hope to ever see in a K mount camera.

All those images are taken wide open. It doesn't matter what aperture you set on the aperture ring when the camera is in Av mode, it will not stop the lens down. This is a symptom of the crippled mount. In other modes you get other effects.

Neither the Leica SL not the A7 series seem to provide anything even resembling what I want. Let me be clear: I want an aperture ring on the lens, and I want an OVF where I can see what aperture I selected using this ring, and of course the metering to work properly with the aperture held open so I can focus. This is not an exhaustive list, just what's relevant to this particular complaint.

If you want to be rid of me to some other manufacturer Nikon would be it. They (and as far as I can tell only they) provide this, but I still don't like their cameras.

But I'm not going anywhere. Maybe away from the forum, no doubt to the delight of people who find me offensive, but not from Pentax cameras. I will try to avoid posting more on this subject in this particular thread.

If no one says anything they surely won't think anyone cares. But some people care, quite a lot. I do want to use old lenses, this is true, but it's not just that. I want to use aperture rings. Always. On new lenses too.

If Nikon didn't make their cameras suck in other ways I would be shooting Nikon, where you do get to use the aperture ring on (almost) any lens that has it (with proper camera support). (And I would have no problem getting all the lenses I want with aperture rings.)

I still choose Pentax, but not because I think they're perfect. I want them to be better.



Nonsense. The lens tells the mount what (relative) aperture you selected, the mount chooses to to not listen to this information. This is a problem of the mount, not the lens.



I don't expect uncrippled mount, but I hope for it. All cameras have features that most users find useless, because that's the nature of features. If you take all of those away you have a camera that no one will buy.

Of course it's not the same. (Although they certainly didn't stop making non-A lenses until much later.) That doesn't mean there aren't people who would like support for these lenses.

It's worth noting that the Pentax 645 system never had any pre-A lenses, and they still support aperture ring readout on the digital 645 cameras.

Some Crappy shots of the new FF Camera

Some cameras put good quality JPEGs in the RAWs, and some don't. Some let you select the JPEG quality for RAWs, some don't. My K5 uses low quality JPEGs with no way to change that, my Q uses whatever settings you select for JPEGs also for the JPEG in the RAWs.

So I have some hope that we will at least have the ability to get high quality JPEGs in the RAWs in future (maybe even current?) Pentax DSLRs. (Selecting RAW+JPEG doesn't help, at least not on the K5, it will use the low quality JPEG from the RAW for previews.)
