Pricewatch Deals / Authorized Canon dealer?

Just wondering if you have to buy from an authorized Canon dealer to make use of the mail in rebates.  Anyone know for sure?

I've been using my 40 mostly as an indoor lens for people or things like museum exhibits.  I used it last week when I did a "house call" for my boudoir business.  Here is an example:

This is at F/2.8 which gives me the DOF I'm looking for.  This is with a 5D3.

Be advised that the first four images are safe for work.  After that they are NSFW.  You have been warned. :)

Lenses / Re: 24-70 f/2.8 L II front coating peeling off?
« on: February 23, 2014, 09:24:27 AM »
I have some experience with anti-reflection coatings in the Ophthalmic (ie: eyeglasses) industry.

If anti-reflection coatings are not perfectly applied, they do indeed seem to peel off over time without the consumer doing anything wrong.  The companies that make lenses for eyeglasses have had a lot of problems with this ever since AR coatings became popular about 20 years ago.   I think this problem is pretty rare in cameras and other optical instruments, because I have never seen it, but it seems likely that a batch of front elements was not properly coated.

As far as I know, there is nothing the consumer can do to make the AR coat start peeling without doing something drastic that would damage other parts of the lens in some obvious way.  It certainly is not due to any kind of cleaning and it is not caused by scratches.  A defective coating is really easy for me to spot because I've seen hundreds, but a camera tech probably hasn't seen many.

My guess is that either the machine that applies the coating to a batch of lenses in a vacuum chamber was not operating properly or the lenses were not properly cleaned before the coating process.  No way for us to know how big a batch is or how many batches were affected.

I don't think it would be appropriate to recall every one of these lenses, since the number of lenses affected is probably small.  In my opinion, Canon should issue a warranty notice like they did for the improperly secured mirrors on the early 5D classic.  If somebody sends a lens in with a defective coating, it gets fixed for free regardless of warranty status.  This is clearly a manufacturing defect.  Technicians should be told what a defective coating looks like so that they don't blame the customer.  It is really easy to spot a defective coating, it's the one that looks like it is peeling off!

What Canon chooses to do about this will tell us a lot about their commitment to customer service.  It will either make them look good or it will make them look bad. 

EOS-M / How come DP Review never did a review?
« on: February 22, 2014, 11:21:13 PM »
How come DP Review never did a full review of a production model  EOS-M?   All they ever did was this preview back in July 2013:

It was not included in their mirrorless roundup published Nov 30, 2013:

I really like the interactive widget that DP Review uses to allow comparison of image quality at various ISOs with various cameras.  I would not buy a camera that they hadn't reviewed so that I can compare the IQ to cameras I already have.

Was the IQ of the EOS-M so bad that DP Review decided not to publish a review?

I could use one of those in a Rebel body.  It would have to come with accurate autofocus and micro adjust to use the prime lenses wide open.  Unfortunately that does not fit Canon's marketing pattern at all.

Lenses / Re: Affected with GAS, Gear Acquisition Syndrome

I ran out of GAS about six months ago when I felt there was nothing left to buy that would add any real advantage to my style of shooting.

My 5D3 is basically the camera of my dreams, so no need to upgrade there.  I have every lens I need.   Some of my old lenses that did not focus well with my 5D classic suddenly became precision tools.

I added lighting equipment, so now I have four Alien Bees - as many as I can reasonably deploy.

Canon has been slow to come out with any interesting new lenses that might tempt me.  I'm still waiting for a fast, stabilized 50mm prime.  Until then my Sigma 50 is as good as anything available in that class, more or less.

It can be really disconcerting when you have had GAS for while, then suddenly have nothing more to buy.  I'm still trying to deal with it.  (seriously)

I'm trying to put more time into my web site instead of reading reviews. Blogging is more fun than I expected.  If you want to avoid the online reviews, check out my blog instead! (warning: some posts are NSFW)

EOS Bodies / Re: EOS 7D Mark II Coming in March? [CR1]

Conversation overheard in the men's room at the Canon marketing department meeting:

Marketing expert one:  "We can't let the 7D Mark 2 threaten our full frame sales, so let's make sure it still has a noisy sensor."

Marketing expert two:  "Dude!  I have a great idea, you know that warehouse full of leftover sensors from the T2i?"


Lenses / Re: Hard choice the 50 1.4 or 85 1.8

I vote for the 85.  My favorite lens.

It will be hard to beat your two zooms as a convenient, if rather heavy, travel kit.  You might find that they meet all your needs.  If I were in your position, I would shoot with the two zooms for a while, then go through your images and see if there is a particular focal length (or two) that you use much more than others.  If so, that would give you a good clue as to which primes you should buy.  It really depends on what kind of subjects you end up photographing regularly.

Third Party Manufacturers / Re: Review: Sony A7R With Canon Glass

It seems to me that putting big lenses on a compact body kinda negates the advantage of compactness.  That leaves the great sensor as an advantage, but still, the practical advantages over say a 5D3 or D800 are not that great.

Your mileage will certainly vary!  :)

PowerShot / Re: Canon S110 vs S120
« on: January 06, 2014, 06:20:59 PM »
I just upgraded from my trusty old S90 to an S100 refurb from B&H for $180.  There were a number of good improvents going from the 90 to the 100.  Not worth the price of a new camera, but at less than half I'm pretty satisfied with the upgrade.

I think you really have to look at the list of features and see which ones are important to you.  I spent quite a bit of time looking at image quality samples posted online and I was not impressed with the improvements over the years.  I think it just comes down to features and perhaps processing speed.

Canon General / Re: Are Metal Mounts Better Than Plastic?
« on: January 05, 2014, 11:59:46 PM »
Interesting coincidence...  I was working with a a fellow pro today.  He recently got a 70D and an 18-55 STM for video.  The first time he put the lens on the camera, the mount sheared completely off.  Canon would not replace under warranty claiming abuse.  He picked up another one on sale very cheaply and it works fine.

I got to try his 15-85.  Now that is a nice sharp lens!

Looks like the sale is over at Big Value.  That was a great price while it lasted!

Used 7Ds are cheap right now and would probably do just what you want!
