AF 200T Bit The Dust
Time to keep an eye out for a sanely-priced AF280T? I can't fathom used flash prices at all. The AF280T seems to have BIN prices around the £70 mark, meanwhile I've seen the AF240Z go for just over £10 and the AF200T for about the same. The AF280T is a great flashgun. It has plenty of settings; ...

Pentax AF360FGZ Auto-Flash: shedding light on wireless flash (and other dark corners of the manual)
Firstly, don't confuse the term wireless with radio. The camera and flash communicate wirelessly using pulses of light, not radio waves. Next, does your camera have the latest firmware? To set up for wireless flash . . . . On the Flash: Power switch to ON, move right hand slider down to ...

AF360FGZ , K20d low light action photography
The old Metz Hammerhead flashguns (CT45 and CT60) are good for that type of application. However you have to use them on their own Autoflash settings, as they will not do PTTL. Stage photography is one thing they won't work with, because the part where you sit is most of the time dark while you've l...

Best flash gun for 60 pounds
Actually the AF280T isn't "dumb" - the auto modes will still work on digital as they use the flashgun's own light sensor and assume that you've set aperture/shutter speed/ISO to what the flash expects. The only mode which won't work on digital is TTL, unless you're using an *ist D or one of the vari...

Wanted: Flash Gun for K100D Super
I would suggest a used Pentax AF280T which you should be able to find for around £40 or so. It doesn't have PTTL but has a very useful Auto mode and it's own light sensor, so it usually gets it pretty close. You can then adjust as necessary on camera.

Backward compatible ?
Right, first you need to check the trigger voltage on your Metz. You'll need a multimeter set to measure DC voltage, switch the flash on, let it charge, then touch the positive multimeter probe to the centre pin of the hotshoe connector and the negative to the side contact. Some Metz flashes have le...

Which camera mode with Metz flash
I guess all will work. For me it varies. I usually use (or start with) Av so I can still influence DOF. When I want to be really fancy I use M so I can influence both DOF and the effect of ambient light. I also use M when I find that the camera tends to use longer shutter speeds (like 1/45) that ...

Mix & Match Flashguns
If the voltages are safe and the hotshoes match then they should work in manual mode. I think I remember seeing some generic flashes which worked in a similar way to the Pentax Auto Flash system (where you set the shutter speed/aperture/ISO to what the flash expects and it will then use its own ligh...

Quick Preflash Question
I think part of the problem is that TTL sensors didn't meter off the sensor correctly as it doesn't behave like film and this was the easiest option.

Quick Preflash Question
The built-in flash is to be avoided at all costs. You can disable pre-flash by using manual mode on any flashgun. The onus is then on you to get the exposure right, but that isn't difficult with a DSLR. You can either take a series of trial pictures until you get one right, or you can work ou...

Wireless trigger for studio lights
Yeah, but only up to about 4 metres ... Depends on the situation, if it's dark you can go a lot further. Have used the AF540FGZ from around 7 meters away on a cloudy day but you need to be sure the sensor is facing to the camera.

Super A/TTL Flash/M lenses
If I put my Super A in Av mode (camera set to auto with lens set to a numeric aperture, rather than "A") as I would with K or M lenses, will TTL flash still work? Yes it will. TTL flash is controlled by a sensor within the mirror box. It, together with its associated electronics, measures the lig...

how to, using flash
Indeed go for a trial run if you can, even if only for a few minutes, at the same approx. time of day. Amazing how much becomes obvious once you've had a go. Forgot about the ceiling. But 280T is more powerful than I thought (90 vs 120 for the 283 that I use) so should be fine for small group s...

how to, using flash
I'd go with the 40mm 2.8... The lens's faster aperture should give you more leeway to control the flash exposure... Shutter speed dictates how much ambient light the sensor sees... So at full sync (1/180 on pentax dslr's) your not getting much of the ambient light... Aperture controls the flas...

Question about flash/strobist equipment
Thanks all for the advice. David it sounds like youre pretty much into this, I might give you a shout. So, would these flash units be OK? http://www.amazon.co.uk/Vivitar-Electronic-Diffuser-Exclusive-Cleaning/dp/B004S38UYS/ref=pd_rhf_p_t_2 I have also seen this one which is not listed as fi...

Question about flash/strobist equipment
Fairly recent thing to be honest... Had the yongnuo trigger as while and they are fun... I think the Vivitar's are non-specific and just have a central-pin (fire-now)... The 'auto' setting on them is related to a sensor on the flash itself and nowt to do with your cameras meter... Instead you t...

Using independent flash ( e.g. Vivitar 283 ) with K5?
Likewise Don. 5 modified to fully manual with potentiometers replacing the sensor, one modified to switchable between auto and manual. I use the Seagull triggers SYK3.

Using independent flash ( e.g. Vivitar 283 ) with K5?
Just bringing this thread back for a moment... I have a Vivitar 365 with a guide number of 48 (in metres). I've tried it with a slave fired by a small gun on the hot shoe and it can boil oceans. Since it comes with an on-camera sensor unit with variable zoom it is quite a sophisticated beast, it...

Pro Line 180
That is what was confusing me as I could see what looked like an optical sensor. As it is radio that is very good and will mean the equipment we have can be used separately without getting more triggers.

Mecablitz 50 AF-1 digital
huh... one more time Frogfish :) Maybe this might help answer your question. Because the flash only last 1/1,000 to 1/10,000 your sensor is almost instantly lighted so it would be a problem if one of the shutter curtains is moving over the sensor that's why we have a flash sync time. At that ...
