... amazingly, that is why the lenses are called interchangeable ...
As long as you don't open the back!! 😀

No problems. Indeed, don't open the back before rewinding the film.

It depends, Ivzhao. One sound principle is not to leave the camera body without a lens mounted for longer than necessary. Another is not to expose the open mount to bright light: change lenses in your own shadow if nothing else. A third is to keep your lens -- better, its hood, since there's no picture that can't be improved with the use of a hood -- capped when that's feasible. I had trouble with my IIIc recently. Every time I changed a lens in the open, in daylight, the frame in the gate would have a streak of fogging. It was a problem with the light shields and has been set right. I understand that the Bessas' predecessor, the Yasuhara, died because its shutter area was not light tight. In general, it's best to be over-cautious.

Sure, why not? How else would you change lenses? 😛ivzhao said:
I have an R2 and R2a along with a variety of lenses. I've done many, many mid-roll lens changes. Never had a single issue. Not one 🙂
Which is why the Bessa shutters are all "double"/reinforced...to make up for the lack of a mirror that helps block light in SLRs 😉payasam said:

Payasam's post is correct. You should always try to keep the camera out of direct sunliight when changing lenses.
The Bessa is new enough that it's double-shutter mechanism should shield the film, but pointing the camera's open throat to the sun means immersing the camera's vital organs to a lot of unnecessary photons. One of my 50-year-old cameras does fog a bit if I'm not careful changing lenses in daylight. I try to turn my back to the sun and hold the camera close to my body to minimize the amount of light spilling inside.

Vince is right, the same goes for changing films; that light seal can be penetrated by bright sunlight as well. However, in general RF camera shutters are better sealed that SLR's, where the mirror provides extra cover. That is one of the reasons Leica stuck with their cloth shutter for so long. Titanium SLR shutters of the time simply didn't make the grade.

Don't trip the shutter ... !

When I got my first interchangeable lens camera, a Retina Reflex S, back in 1957, I was facinated to look at the shutter with the lens off. (That camera had a non-returning mirror - you had to wind the film, cocking the shutter and dropping the mirror down). I finally gave in and tripped the shutter. Well, let me tell you, it takes out at LEAST three frames! So I never did that again. 😎

Did you think you can change lenses at an empty camera only ? Would not make much sense I'd say ??

For a bit more than four decades, I've been changing lenses, often in bright sunlight: not to see how it's done but with whichever camera it was loaded and being used. I did not once face fogging until three months ago with the IIIc.

Come on guys, this question isn't all that dumb. There are plenty cameras that need special precautions when changing lenses. Especially those with leaf shutters built into the lenses (e.g. Mamiya 6 and 7). These require blinds to be pulled in front of the film prior to unmounting a lens.
The Bessa R2a with its focal plane shutter built into the body is allright though with changing lenses when film is in there.

Peter, some cameras do need special precautions. My point was that even those cameras with which such precautions cannot be taken because of their design, can develop defects. Nothing lasts for ever, and there is always the chance that something may be done wrong in re-assembling a camera. While a millimetre might be an obvious error, even a tenth of it could be enough to ruin a photograph. Therefore I stress the need for care. Paranoia is the best protection for silver halide.
