Dear rvannatta,

Yes I also have the same issue with my ample collected strobes...so what is your problem...set the camera to manual ox "X" set the F stop as the same as indicated on your "Auto" thyristor in use strobe ( I own a Sunpak 443AF, Metz 40Z3, + a Vivitar 3700, those are the ONLY ones that had very low trigger voltage + Central contact only!), so NO problem with the hot shoe contact, among my other 5 strobes two of them Hammer type (Sunpak 522/Metz CL-4),...that can't be use with the K10D. Believe me I can live 100 years with this "Flash issue!

Peace,

Alex 007

Wait I will. With Hoya being a glass maker, one can assume they bought Pentax so they could sell some glass. If they are doing what they ought to be be doing, it is flogging their whole announced family of SDM lenses into production and stuffing the shelves of every retailer with them before the Christmas selling season.

IT seems like a functional macro system is mission critical to having a phtographic system.

It takes a little imagination to mount a bellows on the digital camera, but it can be done (by putting a short extension tube behind it) but if you don't have a macro flash solution one whole
segment of photography is missing.

Over all it seems to me that taking the flash sensor out of the camera body is a step backwards
but maybe it is a precursor of some other really elegant solution they have in mind and not just a way to save 50 cents worth of parts in the cost of manufacture.

It wouldn't surprise me if Pentax delibertely broke the backwards compatibility of the flash units just so they could sell everyone a new flash unit. I now have 3 perfectly good
flash units that won't work on my K10 of which the Pentax ring light is one.

If you know anyone that is anyone, I sure would appreciate a clue as to how they expect us to take a macro photo with their equipment.

Thanks for sharing your impressions. It sounds like SDM is really great improvement.

>> Where I'm really stuck with with the macro flash.

Yeah :( No P-TTL macro flash. And I haven't heard of any plans yet.

It is visibly faster, and quiet enough that
you have to put your ear up to the lens to hear it.

Part of the design of the 16-50 at least is a very short travel for the focus range.

Unlike the oldhand focus that took most of a turn on a helical to find the focus the 16-50 only
moves about a 1" and the positioning is done what appears to be a stepper motor, and is really faster than your eye can figure out that it is out of focus so if you hold the shutter button down (to have it active) and pan from a distant object to a close object your eye won't see anything out of focus even though the mechanics have moved from one extreme to the other.

Likewise if you want to manually adjust the focus because you don't like what the motor did, it has a slip clutch override, andyou can easily turn
the focus ring to manually tinker with the focus if you want/need to.

Just to see the difference I put the lens on my istD, and it works there in the traditional way
but that way sucks in comparison.

I was almost ready to dump my perfectly good istD on ebay until I figured out I had another
problem that I need it for, and that is the Flash
issue.

All my flash units are of the older and now unsupported (by the K10) technology.

Where I'm really stuck with with the macro flash.
I have an 080C ringlight flash unit which works as well on my istD as it did on the SuperProgram it was designed to work with, but alas, no work on the K10.

Thus it seems that the istD has to stay around
for macro work, until a macro suitable flash solution appears for the K family of digitals.

And I'm not sure there is a 'macro' solution
any thoughts????

Is SDM really so much faster?

rvannatta on "50mm battle: Pentax vs. Nikon"

rvannatta — Mon, 27 Aug 2007 06:04:45 +0000

Other than the fact that 50mm is too long for the format.

I just got an SDM lens and while I have no optical opinion on it yet (I got a 16-50), I have a mechanical opinion, and that is that I don't want any more non SDM lenses.

The SDM is one of those Oh my gosh improvements

http://www.dpexpert.com.au/archives/2007/07/_sigma_70mm_dg_macro_lens.html

They like it for superb optical qualities, excellent sharpness and colours, Limited/Full focus switch.

Dislikes for slow and noisy autofocus.

Nice. I think that 50mm f/1.4 along with the Tamron 18-200mm will make a nice starter kit for me.

Japanese blogger デジ眼.com has tested the performance of the two normal 50mm wide aperture primes from Pentax and Nikon. Look at the full size samples with the different aperture setting.

Pentax FA 50mm F1.4 on K10D vs. Nikon AF Nikkor 50mm F1.4 on D80. All pictures taken with the same exposure (in manual mode). Untouched JPEGs straight out of the cameras.

Both lenses are really good. It's hard to tell one from another.

I have the Sigma 70mm EX DG Macro lens I love it...my Tamron 90mm macro is sharp... the Sigma is like a razor. The 70mm and my Sigma 17-70mm lens will be my 2 main lenses: the 17-70mm for my walkabout lens and the Sigma 70mm Macro for portraits and close-up work.
I am glad to see this forum evolving...good stuff!

Best regards to all

And one more report by Fumio Nakamura: now about power zoom feature that K10D support with restrictions. In Japanese, auto translation.

Also, you can find interesting review of the Tokina AT-X 535 PRO DX 50-135mm F2.8 which is fairly similar to upcoming Pentax (and Samsung) DA* 50-135mm F2.8. Most of the full size samples made with Nikon D200 so it is easy to imagine how DA* will perform on the K10D.

Recently announced for Pentax K-mount Sigma 70mm F2.8 DG EX macro lens was reviewed by ePHOTOzine. "The lens proved to be sharp right from the outset at f/2.8 and stays that way right through to between f/11 and f/16 where reciprocity starts to come in and degrade the image slightly... ...Distortion, measured with the Imatest distortion module is negligible with a reading of 0.17% pincushion, which is visually undetectable. Chromatic aberrations are so well controlled..."

Also take a look at this gallery:
http://www.dpexpert.com.au/gallery/PentaxK10d

All the photos were taken with the Pentax K10D + Sigma 70mm F2.8 DG EX macro. Author complains that the lens is a bit on a slow side. "Focus can go a bit woolly on low contrast subjects."

Impress Watch continue publishing articles on Pentax's latest and most successful digital camera.

First one from today is a short review by Fumio Nakamura. It contains visual size comparison of K10D with the Pentax *istD, Canon EOS 20D and film SLR Pentax Z-1P. Also some full resolution shots made with old Pentax lenses (15mm F3.5, 85mm F1.8, FA* 80-200mm F2.8 and mirror telephoto zoom 400-600mm F8-12) available.

The second one is a couple of beautiful Japanese models shot by Kazuhisa Nishikawa. K10D + good old lims - 31mm and 43mm. If you tired of recent K10D samples tsunami, just relax your eyes :)
