Tilt and shift adapter

Anyone got experience of this? It would come in very handy.

Re: Tilt and shift adapter

Hi there Dave!

I have had a look at these and also the just tilt version which is much cheaper. My issue with both of these is the OM lenses you would use them with - I cannot afford anything particularly wide to use with them (once you get past 24mm they seem to get very expensive very quickly!

I am tempted to have made a shift adapter for 4/3 to m4/3 - I have a Sigma 10-20 to go on it which should have a larger image circle to compensate for the shift (I believe it was designed for APS-C sensors). My plan is to take apart a cheapo MMF copy and have machined a dovetailed slide of the same thickness as the MMF and bodge the wiring onto it somehow. I'll let you know how I get on.

Cheers,

Ralph.

Re: Tilt and shift adapter

I have had similar thoughts to Ralph, I do have a 21mm f/2.0 OM lens but that would only make for a 42mm shift lens on M4/3rds so perhaps not suitable for architecture unless you can stay far enough away from the subject. Even the 18mm f/3.5 OM lens would not be particularly wide. The problem with using a lens designed for APC-C is that the image circle, though larger than 4/3rds, is quite a bit smaller than full frame so the amount of shift possible would be limited

I would like to explore the possibility of an adaptor for the 12mm f/5.6 or 15mm f/4.5Voigtlander rangefinder lenses if their rear elements don't project back too far

Cheers,

JohnGG

Re: Tilt and shift adapter

Hi there John!

My thought about the amount of shift I'd be able to get is that although the OM shift lenses generally moved 15mm or so, that would only be half a frame of movement - with a four thirds sensor you would only need 7mm or so of movement to lift the lens up half a frame. The APS-C sensor isn't just bigger, it's also 3:2 so a 4/3 sensor should be able to move more in the image circle.

Cheers,

Ralph.

How did you get on? (Sorry to pick up on this 3.5 years later!) And why does no-one make such an adapter? Is it because most Four thirds lenses produce too small an image to allow for shift? (I'm not bothered about tilt but would quite like shift for architecture)

If you use any (non-shift) lens on the format it was made for it will have too small an image circle. A full frame lens on 4/3 or m4/3 should be good. Similarly, a large format lens should be good on FF.

Laowa are to make a Magic Shift adapter later this year. As it is for their 12mm lens, available in various mounts, you may be able to get one with the lens and camera mounts of your choice.

Re: Tilt and shift adapter

I just looked on Ebay. As I found before, a number of "shift" adapters are being offered which are tilt with no shift.

Shift would be more useful to me than tilt I think.


I had a play with the Canon TS-E lenses on a course a while back, on a Canon full frame body.

Large format lenses usually allow for movements on their designated format so would be well over specified for FF. A lens that only just covers a 5" circle is of limited use on my 5x4 monorail.


Medium format will typically have enough coverage for FF tilt/shift. I think I've seen one or two adapters for these around when browsing e-bay. Pentax certainly did fixed adapters for both 645 & 6x7 lenses to 35mm.


Getting wide enough FOV for MFT (or probably even FF) will be a real pain with any of these larger formats. My 5x4 camera worked out a much cheaper approach for shift work, but I've yet to sort out a digital output for it!

Re: Tilt and shift adapter

I think Mike is referring to the widest focal length generally available for larger formats, Harold. When did you last see a 24mm lens for 5x4?

There are available a few tilt/shift adapters for Pentacon 6 lenses on Canon EF. The latter is easily adapted to many other mounts - but the widest P6 lens I can think of is a 30mm *fisheye* - not worth bothering about!

Re: Tilt and shift adapter

Just thought I'd post something on the likelihood of people experiencing some disappointing results as a consequence of using the shift and especially, the tilt functions available on products like this.

Whilst this sounds an interesting concept/product, first of all, I would suggest users of this employ lenses which cover FF, rather than the APS-C format, so you stand much less chance of incurring distortion etc when at the adaptors extreme shift position.

I also would have thought that the tilt function, is likely to deliver far more distortion, and impact on the angle that the image strikes the sensor at. This is not much of a problem when using film, but potentially will be with any sensor, because they are designed to 'receive' light as parallel as possible to the sensor's surface.

I would guess that what people are also likely to experience, is a variation in the level of exposure, relative to the angle which a lens is shifted or even more so, when an optic is tilted, relative to the axis a lens is designed to be used at.

Re: Tilt and shift adapter

I have a tilt (OM) to 4/3 and OM 24mm and 35mm shift lenses. I have yet to find the need for both functions. The shift lenses are great for architectural shots. I have used the tilt for a macro but have yet to do much of that.

http://www.fredmiranda.com/forum/topic/1247442/0

Remember that either movement needs a lens with a large image circle.

Re: Tilt and shift adapter

Hi there Harold!

I have a tilt adapter for my m4/3 gear to use with OM lenses, which seems to work well with a maximum tilt of 8 degrees. Even at the maximum I haven't noticed any serious vignetting or loss of sharpness.

My shift adapter (concept, so far) should be ok for small shifts within the normal boundarys of the APS-C image circle from the sigma lenses. Interestingly I have found on a Canon forum that you can use the 10-20 on a full frame camera, where it will give full sensor coverage from 14mm to 20mm - so I could have more extreme shifts if I don't use the full wide end of the lens.

Cheers,

Ralph.
