Easy lens changing

My policy has always been one lens one camera but with only one Olympus and 3 lenses that's not possible . I hate camera bags so that's not going to happen so how do you do it ...take lens off camera ..find lens cap in bag ..fit select new lens remove lens cap fit to camera .now some of this takes three hands etc
So the solution is to mount two 4/3 mounts back to back and suspend them from your belt or whatever . I used two extension tubes and fitted the mounts back to back with a black plastic separator .
So now you have lens no2 hanging from your belt ..you take lens 1 off the camera and fit it into the empty F mount. Then remove lens 2 and fit it to the camera.
If you insist on a camera bag then glue two lens caps back to back and just swop the lenses end for end .

The one in the photo is for Nikon but I just ordered a set of extension tubes for 4/3 and will strip and fix them back to back.
there is a commercial version by Peak Designs but not for 4/3.

I've ordered 2 lens caps in order to do that.

I'm going to use double sided foam tape to attach them back to back. Good though modern adhesives are, the bond can fail abruptly (and catastrophically) with thermoplastic plastics. Thermosetting plastics are generally safer in this respect. A tape bond will fail progressively hence giving warning.

Re: Easy lens changing

This is a nice idea. I think there might be some commercially available contraptions available made expressly for this purpose.

Re: Easy lens changing

One of my cameras does not have a dust removal system due to being converted to IR. So I always fit a lens back on the body as quickly as possible.
Take cap off the lens I'm going to fit - but the lens down somewhere secure & readily to hand - take lens off camera & fit replacement - then put the initial cap on the new lens.
With smaller lenses there's no need to put the lens down I can hold 2 small lenses OK...


It only gets awkward when the lens I want is currently on my other body.

Re: Easy lens changing

You can get these (this is for Canon) -

https://www.amazon.co.uk/Movo-Multi-...nger+and+strap

and for Nikon, Sony and Pentax but, silly as it may sound, not it seems for M43.

Re: Easy lens changing

If I understand it correctly, the spare lens is just hanging from your belt. I am unsure I want the spare swinging from my belt, open to bangs and crashes.

Maybe I have misunderstood??

Re: Easy lens changing

I have been using a Movo lens changer since March this year - see http://e-group.uk.net/forum/showthread.php?t=47495


Mine is MFT mount although it is not currently available from Amazon UK.



I find it very useful for quick lens changes in the field, although I only use it for smaller lenses, up to my 40-150 f/4-5.6

Pardon me if I'm misreading you, but what part will the back to back lens caps do? It seems like you're relying on supporting a lens with it. I would want a proper lens mount with locking pin (such as a modified extension tube) for that purpose & screws & nuts to connect them, like this, but maybe I've misunderstood your purpose. For my part, a messenger style bag is my preferred method, or Lowepro Flipside 400 AW.

No, I'm just going to use the back to back set up for storing the lenses compactly and conveniently in a bag without them bumping around into each other. I think that others on the forum have also done it

Re: Easy lens changing

Do you use a body cap to keep the lens carrier dust free?

Where do you park the un-mounted lens at the start of the changing procedure??!

Re: Easy lens changing

If you go to the Peak designs site there is a video showing how it all functions.

i have not had a problem with dust in my Movo carrier, perhaps because it is of metal construction and does not attract dust as plastic would. If, say, I have the 12-50 lens on my camera, I remove that first and fit it on the spare mount on the carrier and then remove the 40-150 from the carrier and fit it to the camera - it only takes seconds. There is a central partition in the Movo carrier which protects the rear ends of the lenses and I keep clear filters on my lenses so I don't need to bother with lens caps. The Movo is on a long neck strap such that the lens not in use clings quite close to my body.

I use Araldite with no problem to date. It's a great way of storing two small m43rds primes in a bag that is designed for larger format kit.

Araldite's great stuff for bonding thermosetting plastics, but the plasticiser used in some (most?) thermo plastics can compromise the bond.
