K-7 Feature Questions

Not that I have been able to discover with my sample.

It lets you access the following (and i am going from memory so I may miss a few).

• ISO
• Program line
• digital filters
• Extended bracketing
• Distortion control
• Aberation correction
• Shadow correction
• Highlight detail correction
• Capture mode (JPEG, RAW, etc.)
• Quality

And there may be some others, but I don't recall right now.

I just wanted to know how is the new af system performance in the low light condition.(compare with the k20d/k2000)

thx

RAW will always be full information from the sensor. However, the K-7 now compresses DNG files.

AF performs pretty good in Live View, but not quite as good as the regular focus system, especially in low light. However, you can tell the camera what focus system to use throught the custom functions (ie. make it work like the K20D during live view.)

Compressed DNG ... Hurray .. Very very good for me.

btw. cropped raw . is it hard to implement? I guess that C has sRAW which is not full size raw .. but I am not sure ..

They never gave us a percent improvement number.

Hi John, very nice of you to stop by at this busy time

I have just one question - has the shutter lag and mirror return speed been improved at all? I'd imagine it had to be, in order to achieve 5.2fps, but can you give us some more quantifiable data or at least your personal impression of this aspect of the K-7?

Thanks in advance and congrats on the new camera - I think it will do great for Pentax!

AF is automatically adjusted at the sensor (ie. as you pan from light to dark areas the exposure will automatically change, but you can prevent the camera from doing this by pressing the AE-lock button).

Also, you can select Auto or manual for the aperture. In manual you can change the depth of field by turning the aperture dial during the movie capture, but this does not effect the exposure unless you have pressed the AE-Lock button.

Have not seen a stat. on this.

Is there a Automatic Focus Lock feature? I see the AEL button, but not AFL.

Thanks John, great idea for a thread:

A) How far can the sensor shift to correct for framing? 1mm, 2mm, or ? This seems like it could be used like the shift on a shift lens to correct for pespective distortion, albiet only a small amount.

B) Is there any limit on the length of a movie? I think the Nikon D90 had a limit of 5 minutes or something.

C) Is there a difference in focus speed with SDM lenses, or any changes in the SDM system?

Thanks for doing this, and I look forward to receiving mine. Any idea when they wilil ship in the USA?

I really want to say it looks like Pentax stepped up their game and delivered a more complete camera that is a serious contender this time, and priced it to sell well. Nice work!

Three more;

4) Is it still possible to do (micro) AF-adjustments to lenses?
5) Are the rubber "doors" flimsy enough to be torn/broken/lost by time?

6) How to activate the settings/info-screen and will it stay as long as one desires?

I've never been this exited about any thread in this forum before. 8o)

Do you really need to quote everything in a post? Please trim as much of the quoted (> ) message as possible, (anything that is not relevant to your posting, and especially picture links).

According to the Youtube video, the in body IS seems improved. Does Pentax feel that they have picked up 1 or more stops of IS, over the K20?

Thanks.

1. Is it possible to have something like the "Fn" button? Advanced Custom Function available: 37, but how to access to them quickly?

2. How to access quickly to bracketing and HDR?

3. If I store some custom settings and then go back to them, how fast is it? Is it possible to do with with one button? At least, with one hand?

Thanks a lot!

I'll wait a little more to have the best DSLR ever! (c)

This is a wonderful thread, thank you for Pentax's involvement in all this! Try getting that from other brands!

This is a question we were discussing in another thread that started today:

1) What material is the BG4 grip made out of, the site doesn't say. I would love it to be the same magnesium alloy as the K7, but since it doesn't tout it, I'm assuming it's polycarbonate like the BG2 and BG3?

2) Does the BG4 hold a remote and SD card like the BG2 does or was that space taken up by the AA battery support?

3) If it holds an SD card, is it just idle storage like on the BG2, or can it actually write to it? (I'd guess no on that...not much of a negative, really.)

4) Not grip related per-se, but per some rumors, it's worth asking: With that "shiftable sensor" idea for recomposing based on a sensor shift instead of camera movement. Can that be used as a limited functionality Tilt/Shift module (for creating intentional DOF limitations?)

5) One more: the bracket button appears to have gone missing. A assume this is now in the shooting mode menu? It's a feature I tend to use often.

I have not seen it in writing, Is the AF correction function still in place like on the K20D.

Also, in video mode, you can set aparture. But what about Iso and shutter speed. Are Pentax going to give control of either, and does the camera control exposure more so with ISO or speed if we can not.

I have also seen a poll that suggests that the bracketting button was used more than the RAW button, do you think that taking that into account Pentax engineers may be able to provide us with the option of switching between them........ or perhaps making it a dedicated HDR button.

With the slight reduction in view finder magnification (not a bad trade-off to get 100% coverage), will Pentax be providing a split-prism and/or microprism collar focusing matte to facilitate manual focusing?

Thanks for starting the thread.

Do you still need to place a remote flash on the body to change the channel of the on board flash?

Does the battery grip still store a remote and SD card?

Are existing wired and IR remotes compatible?

Has anything changed with P-TTL to cause third party flashs to need to be upgraded?

Can the on body AF assist be disabled? When a flash is on the camera, which AF assist is used, body or flash? When the pop up flash is raised, does it revert to AF assist, or is only the new AF assist light used?

The lens correction is mentioned of being available for RAW files via external software. Do the RAW files carry the needed information or is there only a lens database in the external software. If it is a database, will third party software providers be able to tap into it?

The on board flash seems to be higher, is there a revised list of compatible lenses? Something like the table on page 177-178 in the English Pentax K10 manual.

Will the there be Pentax Remote Assistant for the K-7? Is live view exported to this application? Can Pentax Remote Assistant be used for capturing video for unlimited file size?

Is there a time limit on live view or video to protect the sensor?

Can you explain what the WB button does? Is it just dirrect access to the WB menu, or can it be set to provide direct access to manaul WB, or switch between two WB presets, something like AWB to tungsten - tungsten to AWB, Shade to daylight - daylight to shade? If it can be set to provide direct access to manual WB, will it disable AF as well? This would be the way the Samsung's direct WB setting works in the GX-20.

Do long exposures, over ten seconds, still require the DFS process? Is it now possible to switch this off?

Is the copyright and photographer information attached to the video files? Would it be possible to attach a video frame with this information, if it isn't possible to include it in the header of the video files?

Is the one touch bracketing still available? Is it true that one touch isn't available for the HDR feature?

Thank you
Russell

(I'm considering the WR Kit lens as a big FEATURE here).

1. Pentax USA is selling the K-7 body only. Will we have to wait a couple of months longer to get the K-7 with the Kit lens? (I'm assuming that it will be cheaper to buy it this way?

2. Does the 3 shot HDR do any auto alignment of the 3 images?

Do you know how fast the burst rate is on the 3 HDR shots? less than 1/2 second?

It is possible to hand-hold an HDR 3 -shot exposure? Or to do it with the camera merely braced on a bean bag?

Thanks,

Another question, are the burst rates affected by using the CA/distortion correction tool? That is, can you still shoot 5 fps until the buffer is full and then have to wait a while while the images are processed.

Related, how much additional time does it take to record a file using CA/Distortion correction? (Is it noticeable, and if it is, how much longer, fractions of a second, several seconds, etc).

Thanks!

Eric
