I was thinking about the 24/3.5 II.

[/quote]

Yes, I know. I was replying to Brightcolours about the 10-22..

Aperture: It's O.K. I could do without it and just crop later. Heaven knows I have enough MP. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt=':lol:' /> But are there shorter extension tubes at all?

Metering: LV is actually more accurate WRT to TS.

Nope, not true. If so, only marginally. The LV takes its initial reading from the metering already done, I reckon. I can very easily underexpose or overexpose with LV depending on what I point the camera at prior to framing in LV. If you put the camera on a tripod, possibly, yes. However, confusing LV is very easy to accomplish. I know I've taken plenty sample shots where this happened. Measuring beforehand with a seperate light meter is really the way to go with TS. An alternative, apart from measuring untilted and unshifted, is taking a few sample shots, adjusting till right, and hoping light conditions don't change too quickly.



Regarding shorter extension tubes: AFAIK, those don't exist. Some people did make their own, actually, especially for very short lenses, although that tends to be a semi-permanent solution (spacers between mount and lens). It may be possible with some tubes to shorten the height, provided there is enough space to create new holes for the screws affixing the mount, and provided the connection between the contacts is either a long springload or a flexible ribbon cable. It is also possible to turn your own of course, or have one turned, and to keep this a cheap solution cannibalize parts from a cheap extension tube for mounts and connectors.



I don't understand your remark about aperture being ok and cropping later, unless you mean you crop out the centre and hope you have enough DoF at maximum aperture. In that case you could just as well opt for a different TS-E, like the TS-E 45. Using extension tubes with that lens poses much less problems.



Kind regards, Wim

I am shooting TS for more than a year (mostly tilt) and LV works great. No need for EC whatsoever. Could Canon lenses behave differently than alternative ones (i.e. without electrical contacts)?

I'm not a DIY person. The most I got was a flash diffuser. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt=':lol:' /> If they don't exist, I'll manage without them.

What I meant is that I'll make do without any extension rings (assuming 12mm is too long and shorter ones do not exist) and shoot normally i.e. lens attached to the body. Later, if I see a need, I'll just crop.



Regarding longer TS lenses, I plan to sell my current ones (the adapter is not very convenient to operate) to get the 24/3.5 II. Later I'll probably add a Nikon 85/2.8 PC. I'll get better ergonomics and AF confirmation. Naturally, these two are much more expensive than my current kit (Mirex adapter, 35/3.5 N, 82/2.8 N, 120/4 macro) but if you want a wider FL and better ergonomics there's no other way.

Like suggested by someone before, you can use a TC with the TS lens. Like the affordable Soligor 1.7x TC, which is a nice compromise between an 1.4x TC and a 2x TC. It will not give you the same amount of magnification as an extension tube of course (it will be more like turning your 5D mk II into a 24mp APS-C camera), and it will of course also narrow the field of view.







The Canon TS-E 90mm f2.8 is also an awesome lens.

Well, I have the Kenko 1.4X. Great optics (same as the Canon) and full compatibility with all EF lenses.

Yes, but it only gets to 1:3.4 by itself. Now, if Canon were to make an Mk II of it...... And BTW, the 24/3.5 II is compatible with a 20mm tube. So much for theory. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='B)' />

Well, with a 12 mm tube and some tilt, lens at MFD, the object almost touches the front lens, so the usefulness of a 20 mm tube is debatable.



Kind regards, Wim

I don't need 20mm. I'm sure the 12mm I already have will be quite enough. I must admit, I can't wait to have it.

You have your eyes on one already? Or still waiting for the right moment?

It may focus close, but it is awkward as a close-up lens anywhere but in a studio setting. Even using a macro rail I found that with the shortest tubes the distance from the front element to subject is terribly close, and forget longer tubes period. I think brightcolors has the best replies here. I certainly wouldn't recommend it as a closeup lens because of the focal plane to front element distance combined with minimum focus, it is just difficult to use. I prefer just using my ts-e 90 and tubes, and then pan-and-stitch if I want a larger composition for closeup since it is so easy with macro rail on panorama base.

I've actually used a simple table tripod setup with the TS-E 24, and a flash for lighting (directed at the ceiling, with the subject almost touching the front lens, and it did work well, with good results.



I normally would use the TS-E 90 for this type of stuff too, but that was not the question. Use of this setup also depends entirely on the results you want to achieve, not to mention the combined use of a lens, especially if you are on a tight budget (macro, semi-macro, landscape, architecture, even portraiture). Oh, and in some scenarios a TS-E 90 will actually not do for this type of shot.
