Whilst that edition was a significant update to the original, I have always considered this to be on ongoing and developing resource. Apart from the need to correct and improve as things come to light, there are more aspects of working with flash and Pentax cameras to explore. Also things move on in the world of Digital Photography, with new camera models coming to the market and new flash developments, in particular in the field of radio trigger systems that support High Speed Sync. There are a number of areas that now need covering, but not really enough to demand a whole new edition of the Guide, most of which remains relevant and specific to the currently available Pentax Flashes and Cameras. So I have put together the new material and created this shorter ‘supplement’. Eventually as things move on again then this supplement will be absorbed into a new 3rd full edition of the Guide. As always I would like to thank the many forum members at PentaxForums, PentaxUser and thepentaxforum who have supported the Guide, contributed to threads about Guide material, and given ideas and information that have been included. I hope you find this a useful addition and an enjoyable read, and most importantly that it might help to make flash photography with Pentax cameras even more rewarding and successful. Nigel McGregor June 2017 The Pentax Digital Camera Flash Lighting System –Supplement to the 1 2nd edition © Nigel McGregor June 2017 Page Introduction Camera Models & Flash Options The current Guide version (Oct 2015) describes the standard flash options and functions found on Pentax DSLR models over a number of years, from the K10D through to the K3. This is generally a standard flash offering including a built-in flash unit, on-board flash, Wireless Triggering and P-TTL-only flash exposure mode. There were some variances between models in the flash modes offered, but in the main the flash choices remained the same across the range; (the K3 was the first to introduce an 8 step Manual Flash Mode, from Full to 1/128th power settings for the Built-in flash). In recent years there has been a divergence in the Pentax DSLR range and what is offered with flash functions, and so there are now choices when considering the various cameras. Firstly there is the option for Manual Flash Mode with the Built-in unit, which is offered as an additional Flash mode to the standard modes (which are based on P-TTL automatic flash exposures). Then came the first camera to be made without a built-in flash at all, the K3II. This was continued with the K1 ‘Full Frame’. And finally there are models now that do not offer the Wireless Triggering from the Built-In flash unit. The functions that are missing by not having a Built-in Flash, and the Wireless triggering omission, can all be replaced by fitting an accessory flash to the camera concerned, but clearly the need to carry extra flashes, or radio triggers, in place of the Built-in flash, needs to be seriously considered by the photographer and the right camera chosen for their own particular needs. As well there are now variations in the appearance of, and specific items included on the different camera Flash Modes Screen. This is the control screen where the Flash Modes and Flash Compensation settings are made. I will explore these differences and the practical implications in this Supplement section. The Pentax Digital Camera Flash Lighting System –Supplement to the 2 2nd edition © Nigel McGregor June 2017 Page Camera Models & Flash Options (i) Camera Models, Flash Features Listings Wireless Cameras that offer Wireless Triggering from the Built-in Flash: K10D, K20D, K200D, KX, KR, KM, K7, K5, K5II/s, K30, K50, K500, K3, KP Not Wireless Cameras that do not offer Wireless Triggering from the Built-In Flash (Accessory Flash required for Wireless functions): K100D/Super, K110D, K-S1, K-S2, K70 Manual Flash Mode Cameras that offer an 8 step Manual Flash mode with the Built-in Flash in addition to the standard P- TTL Mode: K-S1, K-S2, K3, K3II, K70, KP No Built -in Flash Cameras that do not include a Built-in Flash unit (Use a Hotshoe Accessory Flash or Radio Trigger for Flash Functions): K3II, K1 The Pentax Digital Camera Flash Lighting System –Supplement to the 3 2nd edition © Nigel McGregor June 2017 Page Camera Models & Flash Options (ii) Cameras With No Built-In Flash As of the time of writing (June 2017) this was two models, the K3II and K1. We can presumably expect the continuations of these particular lines of flagship Pentax DSLRs to also offer alternative equipment such as Astrotracers and GPS units, in place of the Built-In flash. So here I will explore the implications for flash use without the Built-In unit. Clearly flash photography with these cameras will now have to be carried out with either Accessory Hotshoe mounted flash guns, radio triggers and radio controlled flashes, or a combination of these types. The cameras still have the capability to operate correctly with Pentax and other Dedicated system flash types, and this includes special functions such as : Wireless (Off-Camera) flash when using one accessory flash as the ‘Master / Control’ trigger on the camera and one or more ‘Slave’ flashes ‘Slow-Speed’ Sync, ‘2nd-Curtain’ Sync & ‘High Speed’ Sync Flash Modes ‘Multi-Flash’ Mode (with the AF-360/540 FGZII flashes) ‘Auto’ Flash Mode (Auto-Thyristor – with the AF-540 FGZ) P-TTL automatic flash exposures, both on and off camera Manual Flash Exposure Mode, both on and off camera Flash-Ready viewfinder indication Automatic Flash Head Zoom with autofocus lenses (on-camera only) Range & Distance indications (on-camera only) Hotshoe mounted radio transmitters can be used to control off-camera radio controlled flashes, and there is a traditional ‘PC Sync’ socket for cable connections to Manual studio strobe lights. The Pentax Digital Camera Flash Lighting System –Supplement to the 4 2nd edition © Nigel McGregor June 2017 Page Camera Models & Flash Options (iii) Camera Flash Modes The current version of the Guide (Oct 2015) lists 8 standard modes, on Page 29. These apply to the group of cameras listed within the ‘Wireless’ box previously here, and mainly relate to functions of the Built-In flash (the slow-speed sync and red-eye modes also apply to Accessory Flashes). Here is the screen from the K7; the actual modes displayed depend on the Camera Exposure mode selected at the time …. ‘P’ Mode will normally reveal all. Without a Built-In flash, there is no need for some of these Camera Flash Modes, and so on these newer cameras without Built-In flash there is no Wireless, ‘Slow-Speed with Trailing (2nd) Curtain Sync’ or Manual Modes.
