Come to think of it, I miss Adam and Neuro as of late, maybe they employed the restraining order 'ignore' button. Ha!Some of us have very emotional affairs with each other. We even fight like married folks.
the EF 100mm already does this on some camera bodies (eg the 90D). The camera can do focus stacking itself.+1 Love the slider adjustment concept. Would make focus stacking way easier and precise theoretically.

All that are in R5It's not quite a ring, but a few solid stops. I can imagine if this is focus bracketing, every step is a defined amount different backwards or forward from the focused point. That would let you make your focus brackets in specific amounts, and if it's electronic, you could probably define how far of focus every step is.
Thanks, that sounds good. Looking forward to the release including MTF and more info about image quality.The arrow focus you describe just sounds like Canon's manual focus guides, which should be available regardless of the lens, as long as the lens is detectable for the body. So that's pretty much a given.
It could indeed be kind of a "focus ultra-fine tuning" for manual focusing.I have no idea what SA means, but I was thinking along the lines of something like a fine focus adjustment to get more precise focus as it is a macro lens at 100mm. If it is I still don't know what SA means. I am only throwing a suggestion out there.
You don't really need focus fine tuning with a RF lens, you can variable focus speed so that it can focus in very fine increments. Ideal for manual macro focusing.It could indeed be kind of a "focus ultra-fine tuning" for manual focusing.
Therefore the + and - markings.
No, not especially tongue-in-cheek. I was the 'he' referred to in Ph0to's post, and while I didn't see just "RF" as being enough 'new' for my original comments ( I was referring rather to the other aspects of this lens), I wasn't concerned to pick up on that (on the basis that everyone can have their own interpretations, so I just wasn't bothered), but when Ph0t0 then picked up on it and posited a response, I then felt maybe I should have made a comment.Was that tongue in cheek? I cannot imagine you would actually expect members here to be checking in regularly akin to texting a spouse.
I'm sure they'll be on the way, but bear in mind you don't get as much additional maginifcation from extension tubes once you get to 100mm focal length (the bigger gains come with lenses of shorter lengths).I hope we get also a set of extension tubes with this lens if it is "just" a 1:1 macro. I expect this would be the only way to get higher magnification with original RF lenses.
If I follow your question correctly, yes. When you refocus, it changes the magnification. That's not ideal for stacking. It is better to move the camera a bit to change the plane of focus.In terms of macro and stacking, Is the use of a slider preferable to focus bracketing (automation of which is built in to some Canon bodies.)?
Of the all of the lens elements move forward and backwards then that is the equivalent of moving the whole lens closer and further from the sensor. Thus extension is tubes equivalent.The patent shows the lens groupings sliding in and out. This would achieve both stepping for focus bracketing and magnification changes. I’m really excited to see how this works. I’m over fiddling with bracketing for my macro work!
But we all know EF tubes are useless for RF!Extension tubes work great with my EF 100mm, easily to 2x.
Yes, yes, I know, I know! I own a Sigma 105mm Macro and use it with extension tubes. The biggest disadvantage of tubes is the shorter far focus and I would like not to use these tubes. But I would like to have a magnification similar to my Laowa 60mm 2:1 Macro just with AF. Spring is the time of bee-flies and catching them in flight is not easy with a full manual lens!but bear in mind you don't get as much additional maginifcation from extension tubes once you get to 100mm focal length
Aah, yes, I know! And if Canon would come out with a fully functioning 2:1 macro, that would be fantastic.But I would like to have a magnification similar to my Laowa 60mm 2:1 Macro just with AF. Spring is the time of bee-flies and catching them in flight is not easy with a full manual lens!
