Been having fun with a R7 which has the new RF mount.

I got this camera for the versatility that all RF mount cameras offer except for IBIS and the R7 has IBIS and is crop and those were the requirements.
Now this camera will use R, FL, FD, EF and RF lenses.
Add to that M39, Nikon F and a host of other lenses that the body's thin form factor allows to be used.
The photos are some examples of these lenses mounted on the R7 (Any R camera will do). There is IBIS, focus peaking and AV, TV, P, M and FV seem to all be able to make exposure adjustments along with ISO obviously for ALL these lenses.
1. Shows the original Canon breech Mount lens mounted, This mount never changed until the EF mount of 1987 the automation changed as time went on but this automation was very short lived.
2. Shows a FL lens with the exact same breech mount but the aperture control changed.
3. Shows a FD lens with the exact same breech mount and the added automation was added in 1971 until the EF in 1987 (16 Years and the breech mount lasted 28 years).
4. Shows the EF-s Lens (Just grabbed it could have grabbed an EF lens equally). The EF lasted from 1987 to 2018 or 31 years. The EF series lenses are totally compatible with the R cameras and no loss of operability no matter how old and have the control ring option that lets them have the same function as the RF mount lenses. So those invested with EF/EF-s lenses no issues using all of them.
5. Shows an old bellows attached to the R7 and using the FLM 100mm f4 and works very well, I even added a FD 2XA teleconverter to the rig and got some interesting shots, worked very well.
6. Finally grabbed on of my Nikon lenses to show it mounted, It was rough because the camera kept trying to reject it but with negotiation it allowed me to mount it.
PS, the bench these were shot on is our organ bench from our 1880 pump organ, thus the scratches and flaws.

Hi all,
Generally, I do a little research before I post a question about photo equipment to the UHH forum. This is more like a survey, and apologies in advance if this topic seems mundane. So here goes: Does anyone use a soft (shutter) release button? This is that inexpensive accessory that screws into the shutter release button on most cameras. They look nice and personalized, but since they don’t fit flush to the camera body, and have a wee bit of wobble, they raise a concern. I’m curious if these buttons will or can cause any long term damage to the camera mechanism. (Full disclosure; I have one or two, but I’ve never used them since my “well trained” index finger is so familiar with the feel of my camera buttons already...no real need)

Consider a closer look at your other options beyond moving the LRCAT. The 'ideal' configuration is your LRCAT resides on your local / fasted drive where the USB port is not a limiting factor / bottleneck to LR's internal operations.

If running out of space, the likely cause(s) are not the LRCAT, rather the actual image files and other software. Placing your images onto the connected HD is the more effective overall corrective action, leaving behind the LRCAT.

Look too at your use of the LR 'back-up'. How often do you run this processing? How often do you manually purge these resulting back-up files? There is no automated process to purge the back-ups. As well, you really only need to perform this LRCAT 'back-up' maintenance on a weekly basis. Then, remember every month or so to manually delete all but the most recent date-stamp back-up within the \backup subfolder.

Look too at your 1:1 previews. During that LRCAT 'back-up', have LR purge the 1:1 previews at a month's age. All these actions help to minimize the already low storage requirement of the LRCAT and all the previews stored with the catalog.

Just move it to where desired, with the LR software closed. Double-click the LRCAT file and LR will launch with that LRCAT file as the current catalog at that new position. It will remember that file and position going forward.

But, ask yourself, why do you want it someplace else? Does your back-up approach create back-ups of your files with the catalog located in this new position? I don't mean the LR 'backup' processing when the software closes, rather I mean your processing where you make back-up copies of your image files, important documents, software install files, and the entire folder that contains your LRCAT.

While LR is closed and you're making a copy of the LRCAT to 'move' to a new location, consider too renaming the LRCAT file to include identification of this new 'master' version, say with MAY2022 or something unique / identifying in the name to clearly identify this file version.
