Anyone in the Denver/Colorado Springs area have a Lens Align?
I'm planning on buying one but they are back-orderded and I'd like to check the focus alignment on my gear prior to a trip in a few weeks.

Nice timing! I recently received my new 5D2, so I'm interested in this topic also.

Call me a skeptic (and cheap, if you like :biggrin: ), but I'm not sold on the whole Lens Align thing. It seems like many people have microadjusted their lenses just fine without it for a number of years. But who am I to say? I've neither microadjusted my lenses (but I'll post back after I do - today or tomorrow) and I've not used the Lens Align tool. So I'll reserve final judgment. Maybe it just makes the task easier/faster. It had better be MUCH easier/faster for $80-$140 plus shipping. :eek:

Chuck Westfall has a good post on the topic (scroll to 2nd article). FWIW, he recommends NOT using an angled chart. This is the technique I plan on following. I'll let you know how it goes.

Edit: More techniques...
From Jeffery Friedl
From Keith Cooper

Edit #2 FWIW, I used Jeffery Friedl's chart and technique this afternoon on my Canon 5D Mark II with both 24-105mm f/4 L IS and 70-200mm f/4 L lenses. The exercise took a little over an hour - mostly reading, printing the chart and set up. Once I started taking and evaluating test images, it went quite quickly even though I tested a number of focal lengths - 24mm, 50mm, 70mm, 105mm, 150mm, and 200mm. My 24-105mm (from the 5D2 kit) required 0 adjustment - cool. :smile: And I ended up applying a -2 microadjustment setting to my 70-200mm. So as it turned out, my camera and lens combinations needed very little (or no) adjustment. But it was interesting and now I know exactly what my autofocus situation is. :smile:

Regarding Lens Align... This was an easy and quick enough procedure that I think I'd recommend saving the $$$ for some other toy. :cool: Each to his own, of course. :smile: :biggrin: :wavey:

Good info, Scott. I'd seen some of the other techniques and I'd thought about trying them but hadn't gotten to it. The lens align may have some merit, especially as a shared tool or if you have a wide variety of lenses or changing equipment. I'll take a look at Jeff's writeup again. Thanks!
