Flash for wedding photography
The biggest problems with indoor flash are usually either red-eye and/or ugly shadows on any background. The former is best avoided by a bracket, the second is mostly fixed by positioning the subject away from any background (even with bounce or a brolly you'll still get a shadow otherwise). Outd...

Flash for wedding photography
Yes to all those questions .... the Pentax term for the modern auto-exposure system is P-TTL ('Pre-flash TTL). The flash head zooms out to 16mm, and the wide panel extends this to 14mm. You could use the panel even with longer focal lenghts to spread the light, but be aware that the zoom head will...

Buying a flash
I have the previous Pentax 540 model and I love it! Having checked the specs for the mk11 version you should note that it has lost the red 'auto-flash' sensor on the front, replaced with a continuous modeling light or video light, which doubles as a secondary fill reflector ... Those are so positive...

Learn to use flash by the weekend?
Like I said, the camera will set itself down to the sync speed, unless you opt for manual, in which case you will need HSS set on the flash, or you will be shooting at low shutter speed for the ambiance and movement, in which case everything will be dandy on pTTL. like my photo. You DO need a pTTL c...

How to use TTL on a PTTL camera and flash
I agree, AFAIK TTL is not available on P-TTL cameras. The flashes will fire, but exposures will be hit and miss. The best choice of mode for older flashes on modern DSLR's would be Auto (auto -thrystor) mode if available ... This needs the on-flash sensor of course. The beauty of it is that the flas...

wireless flash?
Nigel, The flash thinks it's P-TTL, but to the camera it is "dumb" manual. So, no, it's not P-TTL exposure from the camera's point of view. Gareth, that's really odd that it works at all. 1/180s is the fastest speed at which the sensor is completely exposed in one go. At higher speeds the two sh...

Af 360 fgz help
Flash power settings depend on the operating mode ... If you are using P-TTL auto-flash exposure mode, then it is the flash system itself that determines the actual flash power that is discharged for each shot. This is based on calculations made instantly from the pre-flash light reflected back to t...

Af 360 fgz help
I have had this flash for two years or more, buying it whilst enroute in Asia and having had a Metz "lifted" and whilst a have had consistently good results i have basically only used it in auto mode. It seems "much ado about nothing" given what appears to be a "user hostlie" interface with hos...

Metz mecablitz 58 AF-2 digital or pentax af 540 fgz flashgun
hi and thanks for the comments so far, I am torn between the flash units I described, but also the AF-540FGZ II & the older AF-540FGZ, having read reviews it appears that the former does not have TTL which would be simpler for me, and I do agree McGregNi I do need more knowledge on the subject, tha...

Portraits with P-TTL Wireless Ratios
As the proud owner of 2 Pentax AF-540FGZ flashes (Mk I & II), plus the built-in flash unit on my K7, I am a committed user of 'system dedicated automatic flash' for multiple light wireless photography. I really enjoy working with P-TTL automatic exposure control and the flexibility it offers. Radio...

How to use the Flash Zoom
Automatic flash head zoom is only compatible with autofocus lenses, so you would have to manually set the zoom with an A type lens. As Yves said, for many flashes the display will indicate the FF figure. With Pentax we have more sophistication in that the AF-360/540 FGZ can automatically detect ...

P-TTL and M42 Lenses
Hello, no, P-TTL is only compatible with autofocus lenses. Any idea why? ..... AF has nothing to do with the calculations needed for TTL. Mike, not everything is known about P-TTL exposure metering as there's no publically available technical documents .... but for a practical operational viewpoin...

K1 & K3II Owners Need Not Apply
As an ex K7 owner I can empathise with the workarounds the camera sometimes forces you to deploy! Using fill light and tone adjustments in LR would produce more natural looking results, given a 'clean' sensor. The onboard flash gives a stark artificial look which rarely looks very nice IMHO. That sa...

Older Flashguns.
I think in a way it is a shame Pentax dropped the TTL and went P-TTL. I know it is progress but the AF400 with 2 AF280's makes a very good studio setup and the exposures were always spot on with both the film cameras and the ist DSLR's. It's the main reason I never thought of getting rid of the istD...

AF-540FGZ
Hi Mick. Problem solved. Although no batteries had been left in the flash the contacts just needed cleaning. There was no nasty green muck on the contacts. I took a cotton bud soaked in vinegar and gave the contacts a good clean. Now as good as new and switches on first time no bother. CHEERS Vic.

Using flash in live view
I always use a long exposure and a reflector, if necessary, for these shots. I'm curious how yours is so dark you can't see flowers? You don't get the 'clinical' look with natural lighting. If it's not a completely still day I need a fast speed to prevent blur and a smallish aperture for depth of fi...

Light triggered studio flash is off-sync???
Internal flash isnt very strong. Could be the Godox units optical sensor isnt picking up the flash. Try using a full power on camera flash. Or better still purchase flash triggers.

Flash failure
Looking clean and being clean are the difference between silence and a whine. Clean the contacts first. If possible, get one of these: https://www.ebay.co.uk/itm/111741724919?hash=item1a045368f7:g:ZjUAAOSwYUZcMFYu&amdata=enc%3AAQAHAAAAoLWt124TLrJi3vV381lv5jE5zMFs1Kj2T3qFvQg1DYkXCkVgfyHB9z...

AF160FC ring flash will only fire on Manual Full Power
Clutching at straws here, but have you tried cleaning the contacts on both the camera and flash controller? If the controller and camera aren't communicating correctly than anything might happen. Steve
