>>3566241>Is it worth getting a macro bellows?It depends on what you want to do, but you can get a cheap manual lens macro bellows for like $30 on amazon. Those are plastic and can wear out fairly quickly if you over load them or forget to untighten the slide before trying to change settings or overtighten the slide. If you get a reverse ring, make sure to get the aperture adapter for it too. Some lenses need the adapter so you can actually adjust the aperture easily.
With macro you have a huge amount manual lens options, including lenses from many other camera mount types. You won't be limited, like you would normally be. You'll just need to be an adapter ring (without a correction lens) for whatever mount type you have to the lens's mount. For a reverse lens setup, you only need to get the right sized filter thread for the front of the lens regardless of lens mount type. With $100 you can get a huge amount of ring, adapters, bellows, and extension tubes. Which will allow you to use pretty much any lens you wish for macro. Or, you can spend that much for a vintage manual macro or a bit more for a modern automatic macro.
Here's I can do with a really cheap, vintage, manual, D-mount lens on my D3400. I just reversed it and made a mount hot-glued to a reverse ring & rear lens cap for testing. I have a few adapters to use D-mount with F-mount, but I need to get a step-down filter ring to use it in reverse without hot glue or JB Weld. I keep forgetting to order one.
