Lenses / Quest for the perfect copy?
« on: December 25, 2013, 04:30:18 PM »
Reading the latest thread discussing the advantages of the 24-105mm versus those of the 24-70mm 2.8 II, I saw, as usual, a lot of talk about copy variation.

Couple months back while shopping for a 24-70mm and an 85mm 1.2 II, on the retail sites I also saw the usual talk about trying and trying to get a good copy.

It really makes me uneasy to know that so many lenses are getting shipped back and forth to the places I want to buy from.  Is it Canon I should be concerned about or are there a significant number of OCD types going nuts looking for perfect lenses?

In fact, I myself actually returned an ef 35mm 1.4 to a big retailer because the front element was full of finger prints.  Ironically, the one I got in its place was perfect at a distance but wretched up close and to about 7 feet at less than f/2.0--plus the purple fringing was way beyond what I expected.  I didn't really figure this out in the first 30 days, so I sent it to Canon CPS and was told all was in spec.  I sold it at a slight loss and bought a Sigma 35mm 1.4 instead--and from the same big retailer.  No problems with it whatsoever after an MF adjust of +3.

Back to the 24-70mm II and the 85mm 1.2 II--bought 'em and love 'em.  Neither needs any MF adjust.  These I bought at a different retailer, one that specializes in photography, because from my experience, this retailer takes a lot more care with padding items for shipping.

When I first started buying expensive gear, I also got nuts.  But experience and perspective have helped me realize that the pixel-peeping issues I was concerned about are not influencing the quality of my work.

In poker, there is an expression:  Don't play at stakes you can't comfortably afford because you will play badly.

I wonder if some of the apparently OCD behavior with questing for the perfect lens has to do with passionate photographers well out of their spending comfort zone.

Or are there really so many bad copies of great lenses?

Lenses / Canon vs Sigma MFA
« on: November 07, 2013, 08:09:44 AM »
Two questions, really.

First, how does the Canon method of microfocus adjustment differ from Sigma?  I know Sigma has a USB dock and an app, and that Canon does MFA right from the back-of-camera menu system.

What I'd like to understand is whether Canon is also adjusting the lens itself, as in the Sigma method, or is making some adjustment in the body?

My other question is specific:  Will a 5D Mk III be able to apply MFA to the latest Sigma 150mm 2.8 Macro?  I find clear info about the Sigma 35mm 1.4, but little (and confusing) info about the macro.

Thanks!

I'm not asking for a print tutorial, because I can buy Jeff Schewe's  336 page THE DIGITAL PRINT.

Am I alone in wondering why we need 336 pages of instruction to produce a decent print?

I have a Canon camera and a Canon printer.  Why don't they play well together, without constant adult supervision? 

I'd bet that a significant majority of people who have higher end cameras and printers also have Photoshop or Lightroom, both made by Adobe.

So there aren't a lot of brands involved here.  Canon, Nikon, Epson, Adobe, Apple, Microsoft.  And they have had decades now to integrate and simplify.  So why is it so complicated to get a print to look like it does on my calibrated monitor or even the back of my camera?  Why can I get a $0.24 print from CVS that looks fairly accurate under sunlight, fluorescent, or tungsten, while mine and friends' home printers need test print after test print so people don't look like lobsters with white blotches of fungus?

No, not looking for another tutorial.  Just wondering why in 2013 it still takes a 336 page instruction manual to tell us how to prepare for a trial and error process!

And don't get me started on LR5's still clunky Print module.  (Sure, if you've been using it for years, it works, but try to imagine coming to it fresh or after using PS CSx for a long time.)

Lenses / Are we in a rebate "drought"?
« on: September 15, 2013, 12:05:32 PM »
Seems like last year there were lots more rebates, especially when I wasn't looking for any new lenses.  Are we in a drought?

Lenses / Fingerprint "investigation"? (ef 35mm f/1.4L)
« on: April 02, 2013, 11:13:15 AM »
Received new ef 35mm f/1.4L from AMZN this morning.  Had a tiny person's fingerprints smeared in an arc across front element.  Also had the faintest of scratches around contacts, very minor, but indicating somebody had already tried the lens.

Expected usual replacement scenario, but was told by a rep and a supervisor that this item was under investigation by AMZN because of many similar complaints from customers.

Sure enough, even though over the weekend there was no note about "Only XX left in stock; more on the way," the item is currently only available from third-party sellers.

Now, I've done a preliminary check of the lens.  Seems wonderful, indoors by incandescent and outside in super-bright daylight. Image quality great, and I love that shallow depth of field and minimal distortion. The fingerprints wiped off and the front element looks to be scratch free, as does the rear.

Question:  Who would keep, who would return for refund?

Another question:  Has anybody else received a new Canon lens with fingerprints?  (This is my first time seeing them.)

Thanks!

EOS Bodies - For Stills / Speeding AF point selection on 5d Mark III
« on: March 24, 2013, 04:56:47 PM »
Has anybody else wished that the multi-controller would allow continuous movement from AF point to AF point when held?  As it is, we have to keep thumbing it, as it stops at each AF point.

I know we can do this with the Quick Control Dial; however, being able to stop at each point or continue moving until we get to the AF point, using just one control--the multi-controller--would be a very efficient way to work.

I'm finding that I'm simply missing focus on occasions because it takes too many thumb motions to get to an AF point.  As a work around, when anticipating moderate to quick action, I limit the number of AF points to choose from and also choose AF-Point Expansion, but even when configured this way, I'd love for the multi-controller to allow continuous movement from AF point to point until I release it.  (I do like the wrap-around ability very much, and I keep mine set that way.)

Would this be a firmware type of modification?
