Again, Canon does NOT offer all-manual lenses that fit current cameras ... which is why it is "tedious" to you ... which is also
why you need the 3rd party $99 mount to adjust electronic communications.
Only Nikon has kept its original F-Mount, whereas Canon dropped its elder mount in 1987, so Canon's non-electric
elder manual lenses no longer work on the newer EF mount.
Again, see above. Reverse macro with Canon is not as optimal as with Nikon manual lenses because all of Canon's lenses have electronic gadgetry (except
If I shot Canon, I would use the MP-E 65mm.
For the 5th time, you don't need to "make life easier" if you are shooting with an all-manual
lens ... you shoot Canon, so you don't know what "manual aperture" means.
If you shot Nikon, you would realize that you are NOT "stuck" on a given aperture, precisely because the manual aperture ring
enables you to freely-adjust the aperture from the reverse position as well.
1) There are manual lens available for Canon from other manufacturers, from manual focus to manual aperture if you want it. I am very well versed in macro photography, from reversing rings to extension tubes to a number of 1:1 macro lenses. I also am very versed in all Canon lenses, having owned too many to count, although I try to keep that list updated in my Previous Equipment link. I don't need a history in FD lenses or why you using a reversed manual lens is easier than using a reversed electronically controlled aperture lens, regardless of manufacturer.
2) We don't need a $99 device, it just makes it easier and allows the camera to focus, meter, etc. We can make due with a $15 ring too, which is what the shot I provided was made with. However having the camera fully aware of the lens, and able to meter, AF, and shut down the aperture at the time of the shot has some nice advantages. Shutting down the aperture with a simple reversing ring on a Canon DSLR is quite easy, you simply set your aperture, hit the DOF button, and dismount the len, viola, the aperture has manually been set much like switching the aperture ring on your lens.
3) This is a Canon forum as well, so you can certainly try to retort what you want regarding Nikon, however I am supplying info for the Canon shooters' benefit here.
4) Also we can indeed use FD lenses provided we use the Canon M3 with adapter. So we have the same ability you do with your Nikon and manual aperture lenses, should we choose to use that camera.
I really don't know why you are being so argumentative, because nothing I have stated is incorrect, nor did I ever say anything about the Nikon side of the house. I am only providing info and insight toward the Canon shooters. Please choose to ignore all I am posting since you appear to primarily be a Nikon shooter, these things don't pertain to you, but do to a number of other readers. Even though this forum has been opened up to all other camera model shooters with the advent of AMASS, I am very sure a majority of members are still Canon shooters on POTN, or at least own a Canon, so my info and the others' input are all good info for this thread.
