It is possible to use old M lenses in Video?
I try it and the screen is black....
I've already put aperture ring permition, it works only for photos, without live view.
I suppose it can't meter with manual M or K lenses
Anyone with success?

Thanks!

Oh yes! It definetely works with M or K lenses. I use the K50 1.2 with the K-7 and already had other K/M lenses that did work properly.

Furthermore, the K-7 uses some kind of new aperture control in video.
I can adjust the aperture on the K50 with the aperture ring, exposure is adjusted automaticely.

What am i doing wrong?
do you configure anything in the menu? It gives me all black screen...

henrx · 10-16-2009, 10:05 AM

What kind of black screen,
the same black screen that appears, if you switch the aperture ring of an auto-focus lens from it's A-Position?

Edit:
Well, that screen has the hint "Press LV Button!"

Must be another black screen.

Well, the only Menu setting enabled is C.38 - 2 [Aperture ring permition] - as you have it, too...

Ok, it's working now! maybe the custom function for aperture ring was not properly in 2.
Thanks!

K lenses in video without 35mm adapter....here i go!

With old M lenses, when I lock the exposure with AE-L, and then press the shutter to start recording, the image becomes very bright, over exposing complitely.
Anyone with this problem?
Why it happens?

Thanks!

henrx · 10-17-2009, 05:20 AM

Same with me...

I guess there might be just no proper AE-L with K/M Lenses.

I therefore first start to recording then adjust the exposure and aperture as needed and then I'm able to use AE-L.

jogiba · 10-17-2009, 06:31 AM

AE-L should work with any K mount lens. BTW AE-L is indicated on the LCD with an * on the top left next to the movie icon.

Edited my post about AE-L. No proper AE-L with K/M Lenses.

If you press the AE-L button and then start to recording, the K-7 overexposes as NunoBarbosa explained...

Didn't you notice any of that?

Yes, AE-L locks fine, but after start recording...really strange we have to do that way.

Let's dream about full manual controls in a future firmware.

From my quick experiment last night, the v1.02 firmware version solved this overexposure issue...
It's still visible on the rear LCD in Live view when starting a movie, but the camera doesn't record these frames anymore...
