I wan to try and make something similar that will give a 24mm perspective. What is the 75 in 35mm FL?

a lot lol


Next on my list is a shorter medium format lens to do this. I'd like to get a 30mm, which is actually a fisheye for medium format, but they're to pricey for what I'm doing.

Do you mean "what is the 75mm lens on 645, equivalent to what lens in the 135 format?"?...50mm

Do you mean "what is the 75mm lens AOV equivalent to on the 135 format, when used on APS-C?" ...120mm

You need 15mm lens used on APS-C, to be equivalent to using 24mm TSE on FF camera.

Too heavy, too. I have two of them, and use them as barbells when I need to bulk up.

Hartblei makes tilt-shift mounts for some of the cheapie Ukrainian lens designs. I have their 45mm PCS lens in Pentacon Six mount, which I can adapt to the EF mount. It doesn't have tilt. Might be useful on a 5D, where 45 is at least normal though not wide angle. They have modified the Arsat 80mm lens for tilt-shift on small-format cameras with a range of lens mounts. But their stuff isn't that cheap compared to your project here. Arsat made a 45mm shift lens (no tilt, unfortunately) for the Nikon mount, and an excellent 55mm shift lens in the Pentacon Six mount.

Shifting a fisheye is a waste of time, but tilting it might produce some interesting effects.

Note that if you want to make something sharper rather than less sharp by tilting the lens, you need very fine control. The tilt required to change the plane of sharp focus is very slight for short lenses, unless it really is a miniature that you are photographing.

this looks more like a Lens baby effect than a tilt / shift... does a tilt / shift work like a lens baby? i thought it was basically to take pics of stuff like buildings so they arent distorted.. i like this effect alot though..

The purpose of shift is to allow you to adjust the field of view while keeping the film-plane vertical. That's what keeps vertical lines on buildings from converging.

The purpose of tilt is to adjust the plane of sharp focus to something other than parallel to the film plane. The Scheimpflug Rule says that the plane of sharp focus, the lens plane, and the film plane all intersect. When the lens plane is parallel to the film plane, they intersect at infinity. But say you are taking a picture of a forest floor with the camera on a tripod three feet off the ground. Say also that you are using a 24mm wide-angle lens (about 1" focal length). Thus, the lens plane will intersection the axis of the lens about an inch in front of the film plane. You won't have to tilt it much to tilt the plane of sharp focus to run along the ground--about 1.5 degrees. That will allows the forest floor to be sharp even wide open, though the tops of the plants growing from it will be out of focus. Doing this accurately usually requires a means of adjusting the tilt very precisely and locking it down, such as you would get with the 24mm TS lens.

(You can achieve the same effect as shifting by using tilts, as long as the film plane is tilted exactly the same as the lens plane so that they remain parallel.)

You can also tilt the lens to shift the plane of sharp focus away from the surface in the picture. This exaggerates how out of focus details on those surfaces will be. That's the effect being displayed here. Yes, the Lens Baby is often used for the same effect.

Shifting and tilting are used for different purposes, but often in tandem to control the image on view cameras.

The Lens Baby is a poor man's tilt and shift! Lens shifts and rise/fall and tilts predated TSE lenses by a very very long time, in large format cameras.

Actually, IMO the Lensbaby is different, since it's largely one big aberration :D

T/S lenses are corrected as well as possible.

Don't confuse the tilting and shifting aspect with the single-element lens aspect. They combine to make the Lens Baby effect, but the principles of tilting and shifting remain the same.

With a lens where the tilt and shift is held by your hand, though, the applications for same that require precision and repeatability are probably not possible. So, for images like the ones we've seen in this thread, the home-made project gets a similar effect to a Lens Baby, with the except that where it's sharp, it's sharp. But it would be hard to use for architectural photography or for controlling the plane of sharp focus to bring things INTO focus.

I'm not.
What I tried to say is that the lensbaby simply doesn't have a recognisable "plane" of focus, because it has so much aberrations ;)
It's more of a "spot" that's sharp.

That being said: I like my Lensbaby :mrgreen:

well.....I built one!

IMAGE: http://farm4.static.flickr.com/3288/2690761554_acf159564f.jpg?v=0
Cost me about £55 which is about the same cost as the low end lensbaby over here in the uk.

Not had to much of a chance to use it yet, but its pretty simple (from a tech point of view) and its good fun.

you can see what (crappy) images I took with it here, not alot to see, just tests
