Is PTTL worthless?
Do you get better results if the flash is used off the camera? In that case reflections might not be bounced directly back to the camera? Might help in the reflective jacket situation.

Is PTTL worthless?
For use off-camera, I just place the flash on the back of a chair or a table, or anywhere. Holding it doesn't usually get it far enough away from the camera. G

Is PTTL worthless?
When I have a studio type environment I put them on stands. But when on the go and walking around, I usually just attach the flash to the camera. That being the case, I rarely have issues with the flash off to the side when diffused through brolleys. I guess the alternative to a bracket is ...

AF400T flash guns
The AF500FTZ will not work with the Hot Shoe Grip as it is. You'll need to drill a hole in the top of the grip, deep enough to allow the 4th pin of the AF500FTZ to drop into and not make contact. Then get the hot shoe adapter and synch cord. This makes an excellent hammerhead style arrangement. ...

Studio flash and high speed sync
There is an even better range of lighting which I use quite a lot called Kino-Flo Diva Lites ( ). They look very much like powerful fluorescent lights to me. Are they not? G The tubes come in Tugsten and Dalylight balance and are flicker free, they are also dimmable. I find that using all daylig...

Yet another K100d/K10d flash compatibility thread!
Just checked out the original epz thread ( ) and you mention that you have a Metz... If you want to use the Metz in a known environment, then you can always use it in "M" or "A" mode (rather than TTL)... To use the Flash "A" mode: * Switch camera to "Av"...

Yet another K100d/K10d flash compatibility thread!
So, today I poped by SRS microsystems in Rayners Lane - they made my life a little easier! The only flash they had was the EF-500 DG ST for £99; so I got that! Just to confirm, the ST does NOT have an LCD on the back. It does NOT have wireless built in either. I have yet to try it on the camer...

Yet another K100d/K10d flash compatibility thread!
Having looked at the Samsung (both models) there is no mention of features such as trailing curtain sync or high speed sync. But they do have those features. I have the Samsung SEF-36PZF Besides the branding I can see absolutely no difference between the Pentax and Samsung units. Here's a shot...

Stofen omni bounce for 540 flash???
Bluewhistle, It's worth emailing Stofen directly ;) I did this before they had produced the AF360 Omnibounce. They got on with the job of making one, emailed me when they'd finished it, and I bought it directly. Maybe they're working on it already... Personally, I find that flipping out the ca...

AF-200FG Flash Pics
Ned Bunnell has some shots of the new flash on his K10D on his blog: http://nedbunnell.blogspot.com/2007/06/af-200fg-flash.html Looks a bit of a lump to me (for a 'small' flash), no focus assist lamp, but basic flash compensation controls. No indication of pricing though. Dan

AF-540FGZ Locking pin removal
Mine kept jamming inside for month. (never while extended and locked to the camera) With enough use it seems to have loosened up. Now it works fine every time. All it does is keep your flash from slipping loose... at which point it may inadvertently hit the wrong pins. Dunno if that might ca...

My new AF360 flash has arrived and I have a question
Ok folks - let's set out some of the "groundrules" about flash. In my experience, P-TTL is very good indeed at coping with dynamic situations (and from initial quick tests it seems that v1.30 is better than before). But my experience comes from the days of Manual only and Auto flash using...

Bounce type flashgun
The sensor is a light meter, and it measures the light, then cuts off the power to the flash. Indeed. And presumably, the flash-sensor cuts off the flash when it's measured a total amount of reflected light, returning to it from whatever its field of view happens to be. If there's a signific...

Bounce type flashgun
I suppose the only way to fix this is the way they do with more sophisticated guns - focus the beam from the flash more, so that it comes back from a smaller area. The whole point about TTL is that the light meter sees the same light as the image frame. Usually, it works fine, but my own experience...

Digital SLR and P-TTL flash guide
Just an update on some tests that I've been running... ... The Pentax flash exposure can be completely thrown by any amount of reflected light. Typically you'll get a very underexposed image as the camera attempts to preserve the highlight detail (incidentally this is often a good thing, especia...

Digital SLR and P-TTL flash guide
"(Ever see people in a stadium trying to use flash photography? How much effect do you think their flashguns will have?? Absolutely zero.)" I'm sorry Matt, but I have to disagree. Anyone using their flash in a stadium knows they will get a brightly lit shot of the back of at least one persons hea...
