Lensbaby mount swap?

I've had a Lensbaby Muse for many years originally brought for my Pentax DSLRs. Last night I finally manged to pick up a Composer (much more controllable/repeatable) which is in EF mount.

I can readily use either on my mirrorless cameras via adapters but I'd like to swap the lens mounts on the two units so I can use the composer on my DSLRs & sell off the Muse.

Has anyone else done this?

It looks as if the mounts are simply attached by 3 small screws which seem to be in the same positions on each unit. The mounting plate of the EF version also looks to be thicker by just the right amount for the difference in registration. Making for a very easy swap as long as I can undo the screws. (A quick try last night suggests they are held in place with Loctite - so a little heat will be needed)

As I hoped it proved easy once the loctite was dealt with - my initial attempts failed due to a faulty soldering iron, no heat at all!

Fortunately I found my old instant heat gun.

Re: Lensbaby mount swap?

Would you recommend getting the higher end lens baby stuff right off the bat?

Plus when you press a soldering iron to blue locktite, does the locktite change in any way to know when it has softened enough?

I have a lens element which has quite a bit of blue around its threads, so I do not want to over heat.

I'd definitely recommend the composer over the muse design, with the muse you can't hold focus & tilt tends to be more luck than anything else. I can't say for the optics themselves as only have three none being recent releases.

The threadlock on my threads wasn't visible while the screws were in place so I don't know if any visual changes took place. It's the only time I've used this technique so my experience is very limited, but a second or two seemed to be enough with the soldering iron I used.

trial & error should show you how much is needed - give it a second & see if the screws move reasonably, a touch more heat if they don't...

If the screws go into plastic heat might cause issues otherwise I don't think there'd be any problems if working with reasonable care.

Thank You.

Regarding the Composer; The sweet 50 seems the only recommended lens, tell the truth I have enough 50's and at 100 with m 4/3 I don't feel the need for another. Are you aware of wider lenses that are great with the Composer?

The lens baby is VERY different to any other lens. I don't know where you got the sweet 50 as the only recommended lens that's total garbage. It may be the lens that suited the reviewer best, but that's a very different matter.

The optics I have available are the older ones with magnetic apertures - more of a pain to use but considerably cheaper. both the models I have work with the composer (but are also 50mm lenses.

They do may a wide angle/tele add on kit as well as a couple of newer 35mm lenses these will all work with the composer. I believe even the fish eye works with the composer but lensbaby say that doesn't benefit from tilting so I'll stick to my other fisheyes.

You might be missing the point of Lensbaby lenses if your comparing them to standard 50mm / 100mm lenses .

It's their "faults" that give them their character that their used for and the ability to move the focus point around .

I bought one of the original lensbabies when they came out then upgraded to the Composer when they came out and have about six of the optics to go in it , including the zone and pinhole set .

I use them on 35mm film and full frame sensors , I'm not sure how much of the image cropped out on m4/3 would effect the image .

As most of the image your using these lenses for is out of the sweet spot , I suspect most of this would be lost on your camera .

You would certainly need to look at samples taken on m4/3 compared to 35mm to see if any would be worth your while buying.

Maybe that's why your thinking only the 50mm is recommended on your camera ?
