I don't get the craze about round heads. I think if Profoto hadn't released the A1, there wouldn't be so much craving and copying.

For use in light modifiers bare bulbs (like that of the AD200) are best.

For use as an on-camera flash, a rectangular shape is best (to match the frame of the camera).

Round illumination patterns can be useful to create patterns on backgrounds, but that's a rather limited use case.

AFAIC, one of the best aspects of a round head speedlight is that one can easily rotate a flag (like the BFT).

Yes, it's a rectangular zoom head moving inside the round barrel. I cannot see this working optimally as it's like fitting a rectangle through a round hole. The head probably features a diffusion disc that acts as a rectangle->round converter but I'm sceptical that the rectangular source will not ever show (e.g. at each zoom setting).

It's only about in the range of ~125º-135º degrees.

Well, it's going to be too weak to act as a real modelling light apart from certain special situations and in the latter it will matter that the light comes from a different place in the head. Hence, the shadows produced by the modelling light will only approximate what the real tube will produce.

I'm not knocking the availability of a constant light source but I find it a stretch to call it a "modelling light" when it is not aligned with the tube and is too weak to support any standard modelling light applications.

Overall the V1 could still be a really useful speedlight but I just don't get the excitement about round heads. I find the AD200 to be a much more compelling product, but then I'm not an on-camera flash user.

Did you notice that lenses are also not rectangular? Umbrellas are typically rounded... take it easy.

But frames are.

oftness of light depends on the apparent size of the source, not the shape of the source.

Actually, the shape of the source matters a great deal. Isotropic light modifiers such as dome diffusers, parabolic reflectors and softboxes* are designed to create uniform illumination. Use an anisotropic modifier such as a 30cm wide x 120cm tall strip light, and shadows become harder in the horizontal axis but are softer in the vertical axis.

*softboxes designed with proper internal diffusers that is.

Only to the extent you later mention, i.e., not to a "great deal", provided the dimensions are not extreme (as in a strip light, for instance).

In the extreme cases you allude to, one can conceptualise the difference as the light modifier having a different size, depending on the dimension. In other words, we are still talking about size, not shape. For instance, it wouldn't matter much whether you used a strip light with sharp 90° corners or one with very rounded ones.

The (aspect ratio and shape) differences between a regular speedlight head and a round speedlight head of the size of the V1 are too inconsequential to matter for all but very specialised macro shooting applications.

Yay! And, crap. The price drifted up again.

It started at $179, then $199, then $249, now $259... (we're interpreting the "Reward Points" as the price).

Boo, though, that there's still no word on a TT685-P or V860II-P. Hmph.

But I would also caution that I saw an In-Development/pre-release listing on Adorama before for the X1T-P and that eventually disappeared into the ether when the X1T-S came out. This time, though, I think the chances of this one sticking are good. And maybe a Pentax version of the X2T might be around the corner.

I wish they would take a note out of Cactus's book and just bundle all the firmware for the different OEMs in one unit. But then again, they probably stand to lose a lot of money that way. Cactus as a company doesn't look too financially healthy right now after the RQ250 failure last year.

They would also have to use a multi-brand hot-shoe connector design.

A multi-brand design is advantageous when it comes to sharing equipment between different systems and re-selling value. On the other hand, system-specific hot-shoe connectors have a better chance of avoiding connectivity issues and the locking pin will be in the correct place.

FWIW, Profoto claim they filed seven patents related to their round-head A1 and feel "obligated" (

) to come after Godox for copying their design.

Profoto will most likely sue for patent infringement. We will see.

Mistral75 · 03-17-2019, 10:40 PM

Most likely indeed:

Class A · 03-18-2019, 11:58 AM

Finally granting the patent pending "for the round magnet mount" when there is prior art by Magmod for the same principle for rectangular mounts would be preposterous.

If that's one of the main claims by Profoto with respect to innovation then they should be ashamed of themselves to talk about "infringement".

This talk of "being prepared" to sue sounds like empty threats.

diyphotography has a preview:

First look and impressions of the Godox V1 round head speedlight - DIY Photography

One nice thing not yet mentioned. The V1 can do TCM as a radio master.

Also, nice solid statement that the tube in there is a traditional speedlight tube (straight), not spiral, like the one in the AD200 round head.

morenjavi · 03-21-2019, 12:23 PM

Thanks. TCM is a great function. Yes, it registers the power used on the last TTL shot, and you can let the flash in manual mode with this fixed setting, and avoid the pre-flash. But it's also a way to know if you are near the minimum or maximum power limit on your flash.
