Google Dirks' surname. Interesting first hit! http://trotteyn.com/
Argentina is a bit of a melting pot, but for some reason I guessed Dirk was an expatriate, not a local. No doubt we will find out.

Naciste en Argentina o solo trabajas ahí?
I should try Dutch, or perhaps Flemish, if I were you.

George, read my post again....

Sorry, Takumar is the name given by Asahi to their screw-mount lenses. A few bayonet lenses were also produced under the Takumar name but they lack SMC coating, and are best avoided.

Your lens is actually described as "Takumar (bayonet)" on the lens barrel, and this description prevents confusion.

It won't meter properly on the K10D.

Actually mine gives quite nice crisp images, and I had no problem with it on my K10D, exposure was spot on....

Was my main portrait lens, used less because it was too 'long' and something to do with my later acquisition - FA* 85mm 1.4
I can see why the old Tak gets less use now!

I believe it's a perfectly adequate lens most of the time, but obviously not so good with the light in front of you.

The exposure issue with the K10D gets progressively worse as you stop down. If you were mainly doing portraits at wide apertures, you may never have experienced a problem.

I have K10D and one of the first lenses I used was my old Takumar K 135 mm f2.5 lens...

Result = fantastic photo.

So, is it a K10D problem? My experience says no.
The problem is in metering with K and M lenses, not screw-mount lenses.

There is no reason why you cannot get excellent pictures with any lens provided you expose correctly.

....My advice would be to avoid SMC Pentax-M series and older lenses unless they fulfill a specific need that newer series lenses can't offer. These lenses have an undesireable exposure problem when used with a K10D. This issue is not yet fixed, but we here hope it will be, and soon.

Is this really a problem with the K100D as well? I thought the problem of incorrect exposures using Pentax M lenses was just with the K10D. I am presently awaiting delivery of a K100D myself so I would appreciate hearing from other owners if they they have experienced this problem with the K100D.

Here is a link to one of many discussions on Pentax lens fit rae000.

Hope that helps.

It's purely a K10D problem.

Could be. But the signal should be in binary. Whether the signal is weak or diffused, on is on, and off is off. Sending analog pulses would of course be too prone to errors caused by distance and all sorts of other factors.
As least logically it makes sense to me that way. So I'm not sure how the brolly would make a difference.

I do not actually know the exact encoding scheme -- but it would be cool to have a way to record whats happening and decipher what is being sent/received.

Of course, as in your case, bright light can mask/overpower the signal altogether and cause the signal to not be seen in one direction or the other, or both.
Where you have something in the way of the light path, you are asking for trouble, so make sure that both flashguns can "see" each other.

Brollies often have bits of silvery metal on them, and it is not impossible that reflections could add to the signal. You know: "Send reinforcements, we're going to advance" becomes "Send three and fourpence, we're going to a dance".

I'm sure your problem is of this nature.

Well, you can either pay out for a P-TTL one (like the current Pentax ones, or the Samsung or Sigma equivalents), or get yourself a cheap manual one to get yourself started.

I use one of these and it does me fine, even when the in trickier situations - it only takes a couple of test shots to sort your exposure and then you're off!

Only takes 2 seconds to recharge to full power too, which is nice.

This is good advice.

If buying manual, try to get one with several manual settings - eg: full power, 1/2, 1/4, 1/8.

Swivel and, especially, tilt, are useful, as they facilitiate bounce flash. A sensor is useful, too, as it enables the flash to cut off when it deems that the camera has had enough light for the set aperture.

If you see one on Ebay with a diffuser, and/or a slave trigger, the package will probably cost less than buying them separately.

I find a flash bracket to be very useful to move the flash a bit further away from the camera, and thereby reduce red-eye. I know you can get rid of red-eye, but it's best to avoid it altogether.

If you want to stick to Pentax, the AF240Z is usually pretty cheap, but it only has one manual setting. The AF200T has lots of manual settings, but the head is fixed.

I would suggest getting the Samsung equivalent of the AF360FGZ if the budget will stretch. It'll have all the manual control you could wish for, and you'll never have to upgrade, even when you buy a wireless flash body, like the K10D.

Will this flash work with my K110D ?
Probably not, because the K110D does not work in TTL mode, and the flash unit, unusually, does not appear to have a manual mode. Virtually every other Pentax flash DOES have a manual mode, so this was an unfortunate choice.
