However, this is a big assumption. Many of us like using flashes both on and off camera. If you want to travel light, lugging a lighting bag with you may be a no-go, vs. being able to stuff a TTL speedlight into the camera bag. Event or social shooting, or chasing kids around the house, a single-pin manual flash designed mostly for off-camera kinda sucks.
And while currently Godox doesn't have a TT685-P, I have a feeling that may be because Godox is planning on refreshing their speedlight lineup. The TT600, TT685, V850II and V860II are more than five years old as models. If Godox comes out with something better than a YN-585EX for on-camera P-TTL that you can also use as your radio transmitter for studio strobes?
And, you're also making the assumption you won't need anything more powerful or with a bigger spread than a GN 60m speedlight. But there are a lot of monolight owners who would disagree.
Quote: I own the YN560-TXII and two YN560 III and use them exclusively full manual.
Well, it's not like you actually have a
choice to use them in TTL or HSS, do you?
I get the Strobist mantra. But I also was envious of Joe McNally and his insanely expensive Profoto gear demonstrating how TTL, if you have TTL locking, and group ratios can be seriously nice to use. TTL lets you drag your iso, aperture, and distance, not just your shutter speed. And that's something manual-only users don't get: how quickly/soon they lock in their distance/iso/aperture settings to make the math easy.
Quote: I would like the ability for optical or PC trigger of the TX to allow P-TTL flashes into the mix, but I am still happy. My total cost was low ($129 USD) and the stuff simply works. Notice zero reference to 622 dedicated TX/RX, they are a red herring.
Right. But two TT600 and an XPro-P would be $190. Only $60 more than your YN-560-TX, and you have HSS, and the ability to add in TTL gear, bare bulb flashes, and studio strobes, and still maintain TTL/HSS/remote power/group/zoom/modeling light control over both the strobes and the speedlights.
You throw in a DigiBee400 or something with your YN-560 setup, and you have to cable a receiver to it, and you can only sync it. You decide you want a Godox AD200, and you have to cable a receiver to it, and you can only sync it. You want to throw in a YN585EX you have, and you can only sync it, with the Yongnuo system.
And you saved all of... $60.
Quote: Despite my fondness for Godox, I would likely do the same today unless I really, really, really needed their HSS solution and/or had committed to purchase of body where I might really need a compact and relatively powerful P-TTL flash.
Or. You wanted to expand to more powerful, bare bulb lights with a much more pleasing and even spread than the weird patterns fresnel heads throw. As in, maybe you want to do full-length portraits with just one key light. Or you need to shoot a group of 10 people with one light. Or you need to light up a bigger space than a speedlight lets you. Or you want to shoot day for night and just needed more power.
Quote: There is little reason to go that direction simply to get a Pentax-dedicated TX when I am not able to control anything Pentax-specific other than a TT350P or a $260 V1 or a $350 AD200Pro.
But that's incorrect. The TT350P and V1-P are your only on-camera P-TTL choices; but
off-camera you can use the TT600 or V850II for power/group/HSS control (single-pin manual flashes), and the V860II of all flavors or the TT685-C (once firmware updated) as off-camera TTL/HSS/power/group/zoom control slaves, as well as the AD200, AD200 Pro, AD400 Pro, AD600, AD600 Pro; with group/power/modeling light control AC-powered strobes in the MS, DP III, DPII, SKII, GS II, QSII, and QTII (you get HSS with those, too) series.
Godox's TTL/HSS support (except on the X1R and 350 mini speedlights) is cross-brand when the firmware's updated. I have a TT685-C. I use it in TTL/HSS on the hotshoe of my Canon 5DMkII. I also use it off-camera as a TTL/HSS slave to the Godox XPro-C on my 5DMkII; and the XPro-O on my Panasonic GX7; and the XPro-F on my Fuji X100T.
Also, an
An MS300 has more power than an AD200 and cost about a third as much. About the same price as a TT685, really. It's low-end and doesn't autodump, but it's a nice inexpensive AC-powered strobe if you're going home studio.
Quote: TT600 as a TX...perhaps
Nah, not really. Being single-pin the TT600 can't be an HSS master. I'd actually say, get a TT600 for off-camera and a TT350-P instead of an on-camera transmitter, if you want a TTL/HSS fill flash on-camera as well as off-camera flash at the same time. But it can't do TCM (TTL locking), like the Pro triggers can.
TCM is the big reason Godox TTL for off-camera can be useful. You can shortcut all the chimpa/adjust/reshoot power adjusting or hauling out a light meter, by just using TTL to get into the ballpark fast, then flip everything to M mode with TCM to lock/fine tune the power on the lights. And you aren't plagued with the shot-to-shot inconsistency that manual-only shooters complain is the reason you don't do TTL, back before TTL locking was introduced by Profoto about five years ago. Godox and Cactus only make it affordable about two years ago, so there's a reason most folks aren't conversant with it, and still proclaim loudly that manual is all anyone would ever want; when really what they mean is they don't want to spend more on TTL.
If $60 savings is worth cutting yourself off from this fun, then more power to ya. You do what makes you happy.
