Looking at Field of Views for Different Lenses

By
Real Estate Agent with SurfTheTurf.com, Inc.

I know I've referenced my Canon 24mm tilt/shift lens that I put on my 5D back, but I wanted to show in photographs why I like this lens so much.  This lens allows you to DOUBLE your total field of view.  To use it, you shift the lens all the way to the left, snap the picture, then move it to the middle, snap a picture, and move it to the right and take a third.  It requires some fairly minor assembly of the photos, but NO stitching.  I just put the middle picture on top of the other two and then use a fuzzy eraser to erase the edges and get the 3-photo composite image that is twice as big.  Remember - this is a 24mm wide angle lens, so it isn't a fish-eye and you don't get a lot of distortion. 

Here's an example of one of the images.

Carlsbad home image

As you can see, you can't really tell where the three images overlap because they are perfect overlays.  (This is because the camera body does not move (it's on a tripod), but the camera lens is on rails and shifts left to right.

The blue rectangle is a 35mm lens that I put on my Canon back.  The camera stayed in exactly the same position and I just took another photo. 

The red rectangle is the Nikon point/shoot pocket camera that I use for other quick shots.  As you can see, it gives a photo very similar in field of view to the 35mm lens, but not quite exactly the same.

As you can see, the 24mm shift lens gives a total image that is about 4 times as large as the point/shoot camera.  If one were outside, this wouldn't necessarily be a big advantage.  Often, you can just keep backing up until you get the image of the house framed the way that you want.  BUT INSIDE, you might be able to back up a few feet, but you quickly hit a wall.  AND THAT'S WHY the camera's field of view matters so much.  After I rented a 5D with a shift lens for a few photo shoots, I decided that I just could not get the results that I wanted to get with my point/shoot cameras. 

Please understand....point and shoot cameras are GREAT, and I use them for all my pole photography of miscellaneous work.  But if you want to take your interior photography to the next level, then you need to think seriously about getting more field of view. 

I understand that there have been some special point/shoot cameras with extremely wide angle lenses.  And I've heard that those can yield good results.  I just never saw any of them at the circuit city and the rental shop did not carry point and shoot cameras.

I hope that helps explain why we are getting the kind of great field-of-view results from our rig that we're getting.  Just comment if you have any questions and I will try to respond.

Hey Jon,

I'm not sure, but the 24mm lens should fit on any of the Canon EOS mount cameras.  Go down to your rental store and rent the lens for a couple of days when you have your next listing.  Usually the lens rentals are pretty cheap, and you should be able to get it for $50-$75 for a couple of days, I think.  Try it out and see if you like it.  No matter what, it's a wide angle lens and you don't have to shift it if you don't like what's going on with the camera. 

Just a couple of notes.  PUT YOUR CAMERA IN MANUAL so that you get the exact same light exposure for each shot as you shift the lens.  THAT'S IMPORTANT (I'll revise the piece later to add that.). 

Is the EOS a full-sensor back?  If it is not, then you'll lose part of the field of view, but you'll still be able to shift it and will be able to double the size of the picture that you're already taking.

Thats a pretty awesome lens if I do say so myself and I do.  Also quite a price if I remember correctly but then thats what separates some of us.

The cost of the lens (no camera body) is between $1200 to $1500, depending upon where you get it from.  Adorama sells the US-warranty version of the lens for $1100, tax/shipping are extra.  If you buy it from your local camera shop, you'll pay more of course. 

Final note: This is a MANUAL focus lens, so EOS camera bodies will not auto-focus it.  I usually shoot at f8, and set the focal length to 8ft, and everything looks pretty good.

Hi Margaret,

That lens is really nice!  However it will be a while before I can purchase one... =(  Do you have much experience with photo-stitching?  I basically use that technique as a poorman's shift/tilt, but as you probably know the results are not as good.  If you get the verticals veritical and horizontals horizontal, it's still hard to fix the "waterfall" effect of the floors, especially if there is a pattern like with tile or hardwood.  I'm just wondering if the results are worth dropping almost $1500 for the shift/tilt...
