flash sync cable
If the trigger is just a transmitter, I assume that the cable needs to be connected to the PC socket of the camera. If it's a receiver (basically a light sensor), it needsto connect to the flash. Assuming that your Metz58 does not have a PC socket, something like http://flashzebra.com/hotshoes-sh...

How to use flash with analog body
I have exactly the same issue, I even have the same flash! I haven't tried it out yet, but the manual for that flash can be found here: http://www.butkus.org/chinon/vivitar_flashes/550fd-cr.pdf My understanding of how it works is this. There are two auto modes which depend on the distance to ...

How to use flash with analog body
No you have the auto modes on the flash, which use a light sensor on the flash itself to control the light output.

How to use flash with analog body
I too am learning my way round flash, even with a DSLR it is worth taking lots of notes of exact readings and settings - at least for me for what its worth I have found the AF280T sensor incredibly predicable / reliable even with bounce - remember it takes an average reading and wants to make eve...

product photography lighting -- help
A good result, and one that shows how much cleaning needs to be done to make your product look its best. The detail in your shots above reveal that you didn't do much cleaning prior to the shoot. :lol:

Pentax 540FGZ II HELP
I have a 55mm D FA 645 1:2.8 Lens. The flash unit sets the zoom at 43mm automatically? Should this not be 55mm? or do I need to make manual adjustment ? Thanks I've never checked to see what the AF540FGZ does on APS-C cameras whether it takes into account the crop factor, but since the sensor is ...

Pentax 540FGZ II HELP
On my old (long gone) film 645 the flash speed was 60th. and the lens was 3to2 ratio with 35mm. Or in other words a standard 75mm lens was the same as a 50mm lens on 35mm camera therefore a 55mm lens is the same as a 36.6666666666666666666mm lens on a 35mm camera. CHEERS Vic. Actually the 55mm equ...

Off Camera Flash methods
Thought I would show two methods of 'Off Camera Flash' I use -- the camera is my 1974 ASAHI PENTAX SPOTMATIC F which has a 'hot shoe' and the flash is the infamous VIVITAR 283 -- my one is the 'Made in Japan' version so it probably has the 'high trigger voltage' which could damage modern 'digital' c...

Off Camera Flash methods
I have two 'Made in Japan' 283's, one of them puts 273v (two seven three) across the contacts, the other only 13v. The 273v one has red tape on it for ID and I only use it on a cheap optical slave. I only use the 13v one on manual focus 35mm SLRs or medium format film cameras. Still an incredibly...

Cactus RF60 UK availability?
Ralph, thanks for that link, I'll check out the prices and also the specs for this flash. Thanks also dougf8 for that forum link which has some good information. I'm interested in trying this flash as a single on-camera solution at first, thinking of building into a small system with a couple mor...

Cactus RF60 UK availability?
Thanks for that info Fletcher8. I was thinking of trying one just as a normal flashgun to start with, with a view to adding another 1 or 2 to start a little system and learn about studio-type lighting more. It looks like they can attach to a stand easily. But would I be losing much without P-TTL?...

Cactus RF60 UK availability?
Update - I've looked through the PDF manual, and it does not appear that the front sensor on the flash unit is an actual light measuring / flash output cutoff type (like the old pre-TTL Pentax units). It looks like the sensor on the Cactus is only for remote sensoring and triggering from a master fl...

Cactus RF60 UK availability?
Thanks Ralph & Steve. I am going to start a thread soon about manual flash working on Pentax, with a view to developing some practical tips & tricks .... this would seem to be necessary if using the Cactus as a single unit. The Cactus system appears to offer a great value start to a small multi-...

1/180th - please help me understand!
The 1/180 sync speed is a limitation of the way a focal plane shutter works, one curtain opens and the other follows it leaving a strip travelling over the sensor. The faster the shutter speed the narrower that strip, the sensor at shutter speeds shorter than 1/180 would only have a narrow strip exp...

1/180th - please help me understand!
With the K-30 on Tv or M exposure mode, and an AF360FGZ or AF540FGZ flash set to High Speed Synch, you can use flash at any shutter speed you choose, even up to the fastest 1/6000th/sec. The 1/180th limit is the fastest shutter speed you can use with a single flash of light because any faster, an...

aw flash
Another good deal. I grabbed the previous flagship model from them 2 months ago for £179. The new one has WR and improved P-TTL for the latest cameras, plus a modeling light for both stills and video if needed. One thing to bear in mind though is that the backwards compatibility with pre - TTL cam...
