This one looks like a Puertorrican Cuatro, but with 10 strings?

I guess that is normal, the Cuban Tres (Cuban Three) has six strings

Cuatro (instrument) - Wikipedia, the free encyclopedia

Pepe, although cuatro means four in Spanish, The Puerto Rican Cuatro has 10 strings, while The Venezuelan Cuatro has four strings.

It's a very nice-sounding instrument.

Let's move the musical talk to the other thread, so we don't dominate this one.

My M 50mm f/1.4 not fully compatible with my K7

Yesterday, I tested my M 50mm f/1.4 on my K7. I followed all instructions per Pentax's link and suggestions posted here and elsewhere. The combo worked well while I was shooting in the shade, but all shots were horribly over-exposed when subjects were under direct sun. My setting was: M mode, f/5.6 and ISO 200. I repeated the test using my A 50mm f/1.7 (same setting) and all shots were perfectly exposed regardless of lighting. Did I miss anything or could it be the lens? I had no problem with it when I had my *ist DS, though I remember having to lock the exposure after activating the DOF switch. Do I need to do the same after pressing the Green button on the K7? I would like to keep the lens so I would appreciate any assistance you can give. (NB. I posted this question on another thread this morning but this looks like the best place for it.) Thanks and regards.

It should work the same way it does on your DS. First, you have to go into your K7 menu and set Use of Aperture Ring to 'permitted'. Then compose your shot, hit the green button to do the stop-down metering, then take the shot.

And you definitely need to be in M mode. If you use Av then the lens will be used wide open (for focusing) resulting in an overexposed photo.

As noted, I've done everything strictly according to the book. I will try my M 50mm f/1.7 lens tomorrow and see how it goes. Maybe, my f/1.4 is defective or something. Thanks.

If your camera exposes properly with the A50 then it maybe and probably is the lens. However, use the the A50 in manual mode and use the aperture ring as well to be sure...

Hold the M50/1.4 and turn aperture to f16+/- and make sure the blades are "snappy", if not than this maybe the reason for over exposure...

The only reason to over expose is the lens is not stopping down properly

I can only speak for the K10D and K20D but I have found that the green button metering in manual mode with K and M series lenses can be way off whereas A series and later lenses (with the aperture set to A) is much better. Generally, the smaller the aperture set, the worse the exposure reading although this varies from lens to lens and aperture to aperture. The only reliable way of metering is to use the histogram and adjust as needed.

With the K20D the metering errors are so bad I don't even bother taking a reading now. I take a test shot and adjust accordingly. I have read the K7 and K5 are much better but have no personal experience.

Thank you all very much for your support. I tested my M-50mm again today under varying lighting situation and it performed very well. I guess it just got a bit sluggish after non-use since shortly after I went digital in 2005. Problem solved. Will post photos shortly. I think I will now start hunting for an M-400mm. Again, thank you all very much and best regards.
