R7 and Macro

The positive feedback is certainly reassuring and appreciated. The LED lighting information is good to know.

There are two types of LED lamps, one is driven from just a simple electronics from the mains power supply where a simple capacitor has the task to remove the mains frequency - which results in those lights being pulsed at 100/120 Hz (double the mains frequency). Then there are LED lights with dimming functions, that too is created by pulsing the LED. They too are often found in household lighting. And then there are the high CRI video LED panels, they are built to be used with video cameras and hybrids like the R7, they are delivering a very constant light output that doesn't fluctuate enough to be noticeable in video or photography.

When I spoke with CPS, perhaps I didn’t ask the right question regarding the flash. I may call again they are helpful.

Maybe you were misunderstood (or the person answering wasn't familiar yet with the design change that EFCS has undergone for mirrorless cameras). On DSLR the EFCS didn't trigger the basic flash guns because the flash trigger was linked to the first mechanical shutter curtain. Now the flash trigger is linked to the a separate electronics triggered alongside the electronic first shutter curtain. The reason it doesn't work for fully electronic shutter is the long readout speed of the rolling shutter which is too long compared to the flash duration.

I have the MP-e65 1-5x macro lens and the Macro Twin Lite MT-26EX-RT that I use often with the 1DM4. Any experience using the latter lens and flash with the R7? I’d be using a ef-R adapter. Will also be using the ef 100mm f2.8 macro lens, and extension tubes.

The 100mm f/2.8L IS USM is working nicely, just like the Sigma 150mm f/2.8 EX DG OS HSM (what a mouthful of acronyms)... The MP/E lens will be working as normal, I have seen so many examples in the macro photography forums I frequent, just not the flash gun (it must work else I would have seen complaints about it on the technical forums that accompany the image forums)...
