Has anybody used LensAlign Pro lens & Camera calibrating System? Would appreciate critiques and comments- thanks in advance. I have Canon 20D & 50D and the following L lenses:F4 17-40, F4 70- 200 IS, F2 135 and F2.8 200 primes.

Sincerely
Robert

I have read nothing but wonderful things about it on the web. Here's a link to a how-to video that shows how simple it is to use. There's also a how-to video on the lensalign site. I just bought mine today to align a Canon 50L that's been front focusing.

I have one. LensAlign Pro won't do much good on the 20D, except for diagnosis. Use is fairly easy and straightforward. It's relatively small but bulky. You will probably want the long ruler for 500+ lenses. The main tip is to shoot multiple frames and average or ignore any outliers. Natural light is best.

I've also heard from a few peeps that it works best with L lenses.

Yikes! $179 for a printed ruler and acrylic stand seems like a lot of money.

Yes it is expensive. There are more parts than you might think, but overall construction has a homemade look. It could be mass produced in China for pennies on the dollar, no doubt.

Not really. It works fine with 200-400 VR Nikkors too.

Yes it is, and I had no problems buying one. Tapes has other good stuff like the Whibal cards.

It may be due to the typically larger apertures?

That's what I'd do. I've used a similar chard at a 45 degree angle. You don't need something like this. The angle doesn't even matter - all that matters is that it is the same for all shots as you dial the adjustment in.

I have used the Lens Align on all of my L glass and love it. It works very well and the results are worth the price.

What makes it worth $179 more than this (or similar charts):

It's nicely done, but I'm missing where the rest of the value add is. I'm missing something.

It's not just a chart. There are 3 dimensions to the device for perpendicular alignment, plus the angled ruler of course. There are also some nice little adjustable magnetic indicators to figure out which image is which during review. Obviously some time and effort went into designing the device.

Ok, but don't all I need to have is a graduated scale that is fixed in its place and the camera fixed in its place. You shoot, see what it looks like and dial in adjustment either fore or aft. You don't even need the scale to be linearly spaced as long as it has frequent reference marks. Isn't that right?

Robert ... I have a 5DII and 50D. My 50D is much more difficult to MA than the 5DII because of the greater DOF you are typically working with. I haven't looked at the LensAlign for a few months, but the last time I looked at it the ruler was really to short to work at recommended distances on a 50D. You can check this yourself by computing the DOF for your lenses at recommended calibration distances (at planned focal length and aperture). CLICK HERE for the system and approach I use (plus there is a table of recommended calibration distances if you are unfamiliar with Canon's recommendation in this area).

Good luck,
Bill.

I have to tell you, both of these systems look to me like snake oil. It's not that hard to set up a graduated scale in a repeatable set up so that you can tell if the DOF is centered or not. I've used a variety of focus charts for years and it has always been pretty easy to tell what was going on. You printed your own targets from downloaded files and shot them the appropriate distance and angles.

That all said, maybe I'm missing something. Am I?

It's not snake oil, it's convenience and accuracy supported by a plethora of videos and other support information that takes a lot of the guess-work out. As a commercial photographer my time is worth a lot and I don't want to sit around in my garage thinking of ways to tinker with gadgets in order to save a few bucks. My gear operating at its best is critical to my reputation and my clients needs.
