p.1 #1 · p.1 #1 · Adapter for Olympus 24mm Shift

hi,

i got the famous olympus 24mm shift lens last week. already took some pictures with it on my EOS 5D and it seems to be a fine lens. but it shows a lot of chromatic aberations which clean up to a certain degree in lightroom. now i am wondering if the CA comes from the wrong adapter. couldn´t find out if the 24shift is a floating element construction, if so the right adapter thickness is crucial.

does anybody have experience with it? help greatly welcome.

I have 2 of them (need to sell one soon), using a Kindai adapter. Not sure re: floating element but I think it does have one. the MIR site might mention it, or I can look it up in the lens tests I put online. www.edsawyer.com/lenstests/ - the oly 24 shift is in there.

thanks ed. the kindai adapters are a bit high just for trying. does anybody have good sucess with the cheaper adapters, like the ones from happypagehk?

I have ordered this item on Ebay: 370150734927

Text says it is worked exactly. Unfortunately the lens has a strong play (I'd estimate easily half a millimeter) which of course is much to much for a lens - result are unsharp pictures and I will have to send the lens back to sender :-(

I will have to get another one...

bernie, this is the same adapter that i have now but my lens sits rock solid on the camera. it seems as if there is a lot of sample variation with this adapter and that makes me confident that trying another one might be worth it.

I used to have one of these with a HappyPageHK adapter. Worked great on a 1dsm2.

Hi again, I contacted the seller and he explained me that it is possible to adjust the adapter with the help of a knife by opening up/ widening the narrow slashes on the .... (don't know the english words) inside of the adapter. Fact is, since I did so, the lens sits quite firm on the adapter.

I may order an AF confirm adapter - with my old TS-E 24mm I set the lens to infinity most of the time (for outside architecture). Not sure if the Oly works in the same uncomplicated way.
I also was a little bit dissappointed to find out that in vertical position the maximal shift is only 8mm, I had hoped for 10mm. The new Nikon shift lenses has - if I understood correctly - 11mm in both directions. Unfortunately it doesn't seem to work with other cameras than the latest Nikon bodies.

I only have the Zuiko 24mm/shift since yesterday, weather is very grey but I hope to be able to try it out outside today....

IMO you don't need AF confirm on these lenses. It's not that accurate anyway esp on lenses slower than 2.8. Hum - only 8mm shift in the horizontal position - I was concidering one of these lenses but this could be a deal killer.

No, I said 8mm in VERTICAL (portrait) orientation, in horizontal (landscape) orientation it is 10mm (or 10,5), plus: you can shift in both directions, albeit not to the maximum at the same time.
Question is what are the alternatives?

I had the Canon shift for 2 years and shot thousands of frames with it. There are several issues with it:
1. The lens is not very well corrected and has distortions that are quite strong and difficult to remove because they are not regular (barrel type) to begin with and get even more complicated when shifted. On regular architectural lines it can look quite funky.
2. Despite tilt set to zero the results were inconsistent sometimes a part of the frame (left or right) was slightly unsharp.
3. When shifted the sharpness on the shifted side gets unsharp when shifted more than 6 or 7mm. Therefore the added shift over the Olympus does not necessarily represent an advantage.
Somehow I still managed to get quite good shots with the 24TS-E, but the lens is far from the ideal shifting solution.

The Oly in comparision seems to have only very slight distortion and the edges (from my very first shots) seem to be better than the Canon's. BTW the Oly seems to be a re-worked Oly 18mm lens. You just shift the lens around inside the 18mm lens image circle.

OK but it's still going to be a problem for me if it only moves 8mm in portrait. You can fix teh TS-E distortion and CA using PTlens - it has a special setup for shifted and unshifted as well. It can't fix the lack of resolution in the edges and corner of teh frame though and this is where I was hoping the OL would be much better. Any chance of some side by side comparisons - fully shifted ?

Well, this is the decision one has to make: All those shift lenses for 35mm cameras seem to be compromises.
- The Canon being the most versatile, but not the best quality. One has to wonder what are worth the dozens if not hundreds of hours if the results are a compromise in quality?
- Oly seems (I have only made a few shots) much better in the edges, but only 8mm and 10mm shift. Also no automatic aperture (however an aperture lever that lets you quickly swith from wide open to real aperture value selected on the aperture ring). I also see CA on the Oly, but maybe it is because the adapter is not precise - All that I still have to figure out exactly - I only have that lens since ONE day!
- I also had tried a russian or Ukraine made shift lens - focal lenght was 35mm. It was a catastrophy in every possible way, sent it back....
- A while ago I have read a comparision test and it showed that also the Schneider is not free from the issues the other ones had: Unsharpness when shifted, CA.

- maybe the best solution currently is a Nikon D700 with the 24mm PC-E shift and tilt from Nikon, but it would be an expensive solution, both together cost me almost twice as much as my used Canon 5d + Oly shift and the Nikon d700 itself is not a beast of sharpness...

As for direct comparision shots there is no chance - I have sold the TS-E a while ago, together with my old 5d.
I'd only get a new TS-E if there are serious issues with the Oly 24shift. Which I will have to figure out in the next days and weeks.

Here is a (very) small fraction of my TS-E shots: http://www.pbase.com/alba63/tse_shift_lens

PTlens also has distortion and correction maps for the OL24mm. If you don't need the width of 24 or 28mm then the OL 35 is a superb shift lens and available for reasonable amounts.

Yes, I have PTlens and another correction tool which is probably even more exact.

Concerning the useability of more than 8mm of shift, Lloyd Chambers (diglloyd.com) just started a new article on his very interesting and well- made DAP blog (paying fee) on the new Nikon shift and tilt lenses. About the 24mm PC-E he indicates 9mm shift as the limit for high quality results.
Probably not worth getting such an expensive lens.

What other correction tool do you use? There are limit marks on the TS-E which are 8mm AFAIK but when you have to shift you have to shift....

You may have to shift, but tilting the camera upwards when 8mm are not enough and correcting in Photoshop the rest may yield better results than getting less than sharp edges.

I used this for correcting lens distortion, but the site is not working right now, at least here:
