Confusing Wireless P-TTL Documentation

Thanks for that write-up.

That procedure is somewhat different from the one in the manual. I finally got to see the Channel indication displayed on the camera, for once. However wireless P-TTL is disappointing. I get very inconsistent results, usually on the dark side, with almost no flash intensity control from the camera.

On the other hand, setting the Metz 58-AF2 to Auto and using it wirelessly (in the exact same way) works flawlessly. Flash intensity is controlled precisely using the camera's exposure compensation (not flash EV comp, but the actual EV comp that I adjust using the +/- button), and the results are very predictable. In this mode, the flash is using its own meter to determine how bright the scene needs to be rather than just blindly doing what P-TTL tells it to. If the camra wants +5 EV, then the flash over-exposes by +5 EV.

I think I'll stick to P-TTL for on-camera use and Auto or Manual for off-camera.

Confusing Wireless P-TTL Documentation

I've been trying to get wireless P-TTL working with my K-5 and Metz 58-AF2 flash. When it works, it seems to work fine. But getting it to work is frustrating, and the documentation provided by Pentax and Metz just add more confusion.

For example, the Pentax K-5 manual states on page 190:


And on page 191:


However neither of those thing appear to be true on my K-5. It never displays the channel of the built-in flash. It just shows me the wireless flash symbol. The Metz documentation is an overall non-amusing joke.

I've tried following the procedure for setting up wireless P-TTL as outlined in the K-5 manual, and it fails consistently. When I try it, I get the exact same flash output regardless of exposure compensation or flash adjustment made on the camera. ONCE, I got it to work by accident, and it was great. Flash output was strong, exposure was consistent, and changing exposure compensation on the camera resulted in a stronger or weaker flash, as expected. But since then, I've been unable to replicate this success.

Is there some kind of different procedure to follow on the Metz 58 AF-2 to get wireless P-TTL to work on the K-5? I'm getting really aggravated.

Nope, just that you're not a lawyer and I'm not a lawyer and any attempt by us at turning this into some kind of legal injustice serves no good purpose other than to inflame the uninformed masses and turn this into a thread that I will immediately unsub from if those kinds of allegations go any further. You're gonna start drawing low-brow idiots with that kind of talk.

Oh boy, here we go with complete misinterpretations of law by non-lawyers... what's next, claims of "false advertisement"?

It sucks that this touted feature is so frustratingly unreliable, but Pentax's refusal to let us calibrate it ourselves is nothing more than poor quality and customer service. There are no legal issues to be invented here.

Yep, that's right. If you try to use Horizon Correction, then every picture comes out crooked regardless of how straight the camera was when you took the picture.

It should be noted that my K-7 was deadly accurate with its electronic level the entire time I owned it. And I never heard of the K-7 losing its calibration over time. Only the odd initial mis-calibration. The K-5 is an improvement in many ways over the K-7, but sometimes it seems like corners were cut compared to the K-7.

I wonder if the 645D's electronic level is as unreliable.

Sometimes your perspective to a subject might make it seem like it's not straight in the viewfinder, and relying on the electronic level in such a situation would make that subject appear crooked. But this does not reflect the electronic level's accuracy. It's an occurrence that's even older than photography itself. The only real way to tell if your electronic level is off is with either an external level that you know is completely accurate, or by using a water horizon (ie huge lake, the ocean, etc). Mine's accuracy never changed from picture to picture. First it was always accurate, and then it suddenly became always wrong.

Pentax version of the Sony a77 coming ?
Posted By Hound Tooth

What the heck are you people saying? Do you even KNOW what "30% of incoming light" means?!? Have the basics of photography flown out the window? Have you forgotten that we deal with light DOUBLING when we refer to stops?

If you use 1/3 EV steps on your Pentax camera, then "30% of incoming light" equals exactly ONE CLICK of the command dial (either for shutter speed or aperture, or even ISO if you use the "as EV steps" option). In other words, it's the same as going from 1/30 to 1/40 shutter speed. Or F4 to F4.5. Or ISO 100 to ISO 125. Also known as "completely negligible". The actual result on the image is barely perceptible and can easily be compensated for in post-processing. You people are making a pretty huge deal out of a lousy 30% loss in light transmittance.

Additionally, the so-called 5% loss in image detail is not only subjective, but may not apply to the A77 at all. Sony isn't just enhancing the EVF on these cameras, they're also enhancing the mirror and other technologies with each generation.

I actually found the A77 pretty interesting. Not interesting enough to replace my K-5, but interesting all the same. Sony is finally catching up to the competition in terms of features, and that's a good thing. Most of the knocks against the A77 in this thread are ridiculous and baseless.

And say what you will about 24mp... I like the idea of gaining 4" of print dimension at 300dpi (20" prints vs 16"). That's a damn substantial difference. And the crop potential is also very appealing. Dismissing 24mp based solely on file size is narrow-minded.

To revive an old thread;

My silver K-5 was delivered with a perfectly-calibrated electronic level, it's one of the first things I checked when I got it because my black K-5 from before was mis-calibrated. I've used it for months, taking thousands of pictures, and never had a problem. Then 4 days ago, all my landscape pictures for that day were slightly askew (I rely on the electronic level a lot). When I checked the electronic level, I found it was suddenly off by a solid 3 ticks. All my landscape shots from 6 days ago are fine. So sometime between 6 days ago and 4 days ago, the electronic level lost its calibration. The camera was never subjected to any kind of harsh treatment in that time frame. There were no software failures or freezes. There's no possible reason for the loss of calibration except:

a) the sensor somehow came loose and became askew or

b) the camera "forgot" its calibration

I lean towards b) as a more likely cause because the off-ness of the sensor is constant regardless of which way I orient the camera. Since there's no way for users to calibrate the electronic level themselves, my only recourse is to send the camera back to Arizona yet again for multiple weeks to get it "fixed". And since it's possible for this to happen at any time, I may have to spend money to get it fixed in the future when the 1 year warranty runs out.

As far as I'm concerned, this feature and the corresponding "Horizon Correction" are now completely useless. There's no point in using them if the calibration can go wonky at any time without warning, and if there's no way to correct it myself. I'll have to turn it off on my camera, including all 5 user modes, and re-train myself not to rely on it.

It's too bad, I thought it was a great selling point and I used the feature all the time.

And very little effort, too. I've opened (and won) disputes a few times. It makes the refund come a little slower, but it's very satisfying in the end.

erm... actually that's pretty much the only reason they use those traditional cooking methods at all: time-proven recipes require a specific temperature for each step, and having to figure out new cooking times/temperatures might affect the result. It has nothing to do with the quality of the source of heat.

You have a strong tendency to leap to bizarre, illogical conclusions without having a clue about the subject you're referring to. It's embarrassing.

Nope, you should get the seller to pay for return shipping and a full refund. Go through with a dispute if you have to. No reason why a bad eBay seller should cause you to lose any money. If it doesn't cost HIM money each time, he'll just sell it again to some other poor victim with the exact same ploy.

edit: DON'T get swindled into accepting a shipping refund after he's received the defective item. Get him to buy the return shipping label and send it to you via email. You shouldn't have to outlay any more money at this point.

Stop wishing. It's not. It's the exact same motor they've been using since the lens was released, and it's just as failure-prone as the original. I've got multiple failures over the years to prove it. After the most recent failure, I had it repaired one last time and then sold the damn piece of crap on eBay. Good riddance.

By the way, there's a very easy way to tell where the air transfer is happening in a camera. Just fill it with smoke (cigarette smoke will do, but something more caustic would be great), attach an extended weather resistant lens, then retract it and see where the smoke comes out of. I volunteer Wheatfield to try this experiment with the most expensive camera body and WR lens he owns. Maybe he could try it with every camera body and lens he owns, just to be sure of the results. I'll happily provide some dyed ammonia gas for that purpose.

Again, depends on where the air transfer is happening. If you submerge your camera completely and then extend your lens while the camera is under water, you will get a vast quantity of water in your camera.

...and I will laugh at you and call you names.

On the other hand, if the air transfer is happening where water doesn't typically accumulate, then it should be a non-issue.

This is the mechanism by which dust and mold have gotten into lenses since the dawn of time. It's not limited to zoom lenses, even a prime lens that gets slightly longer as it focuses will draw air into itself (and consequently the camera body).

This is all pretty irrelevant, since there have been other extending lenses that are labeled as "weather resistant", and it's not been an issue before. The DA* 16-50mm extends while zooming. The DA* 60-250mm extends while zooming. The D-FA 100mm WR extends (a lot) while focusing.

This particular instance sounds to me like a defective weather seal in the camera body. So the whole point is moot.

Not so much a "theory" as a very well-known fact...

And no, the inside of the camera does not turn into a "vacuum" as long as the lens is extended. There is air transfer happening.

This is the first time ever hear of such a thing happening (well except for that idiot who used to wash his K-7 under running tap water). I spilled maple syrup on my K-7 once, and the buttons by the top LCD became all sticky and they wouldn't come back up when I pressed them. Dripping a bit of water from my bottle fixed the problem.

I've also been in torrential downpours, violent blizzards and all manner of dusty environments. Never had either my K-7 or K-5 experience any ills from it. So if it turns out the seals on your camera were installed wrong, then I'd say you're a really unlucky photographer :(


Zooming the lens (ie. making it longer) causes a vacuum inside both the lens and the camera. Air gets sucked in, and water can get sucked in along with the air. I'm not aware where the vent holes are on the K-5, but I'd assume they're oriented towards the bottom somehow.
