A few more experiments with the SR1 and a new 100/2.8 macro lens and high res mode have convinced me that it's potentially superb...

The 'potentially' refers to the really small DOF you have to work with when using any macro lens wide open. This will limit many, by requiring stacking to get any significant DOF, whilst the lack of motion controller support and more importantly no flash firing when making super-res shots, will just up the difficulty a bit more

I'm not into the bugs/plants/fungi staples of the macro photography world, so you'll have to wait in that area (I'm sure using that 187MP will be taken as a challenge by some ) but here's a super res shot of an old 8255a PIO chip, with a full res crop.

The 16 bit .psd file of this image is ~1.12GB BTW

This was shot using mode 1

Mode 2 allows for a bit of movement, so is better for real world photos

That is some serious detail Keith , not sure I would want to see the more common and more gruesome macro bug shots at this kind of detail I hoped to see some more high res form the S1 as well I did post a thread but never got a lot of replies

It seems that this product (S1/S1R) might be becoming a game-changer product that is only going to be limited by the ideas on what it can be used for.

The -only- limitation (or annoyance really) I've come across in the couple of weeks I've had the camera and lenses is dust. I'm really thinking that having the sensor 'open' when changing lenses is not such a good idea. The sensor picked up (and retained) more tiny specks (visible at f/16) in a couple of weeks than my 5Ds has since 2015

I note that the EOS RP keeps the sensor visible, whilst the EOS R closes the shutter - based on experience of late I'd like the shutter closed when not in use.

Keith I found the same with my Sony bodies at first. To ameliorate this ,change lenses in a dust free environment , body facing down , and I give the sensor a quick shot with my rocket blower. This has reduced my sensor cleaning markedly, as a macro guy shooting with the lens stopped down you are in the worst position to see the dust bunnies

Nice idea, but as someone frequently working in factories and building sites, as well as studio work,  I'm afraid it's not going to happen

The S1R goes back tomorrow, so it's back to my old fashioned 5Ds with a shutter conveniently covering the shutter most of the time (I'd still keep the S1R if offered - so much else about it is great)

I hope to get a much more considered set of review notes written up in a few weeks although it will be quite selective -no video for example
