Reviews / Re: Herringbone camera strap.
« on: January 27, 2015, 08:05:26 PM »
There are a ton of knockoff Canon Hand Straps, the original E1 strap was very popular, but is now replaced by the E2, which is not well liked.
There are still E1 straps available, odds are that they are not authentic.  They all come from China ;)

Not to ask the stupid question, but have you tried another lens?  Sometimes it's in the lens.  Don't ask how long it took me to figure this out...

Yes, a hair on the rear of the lens will show up and look awful. 

Michael Reichmann of "The Luminous Landscape" also has a extensive review of the 645Z which made me want to go out and get one, but then, I came to my senses since it does not match my usage very well.  I'd still like to have one.

Photography Technique / Re: Which eye do you use?
« on: January 27, 2015, 01:46:11 PM »
I'm left handed and use my right eye.  I could use my left eye as well, but I don't like my nose in the middle of the controls on the right side.

Site Information / Re: Underneath my name

Underneath my name it shows "SX60 HS" What is it and can I change it?

Go out and buy a Canon 1DX and send the camera to the owner of this site.  They will be glad to update your label.  :)

Or Send in a 50mm f/0.7 IS like I did ;)
An alternative might be reading the site information area.  Its a bit obscure, and should be at the top.

Interesting, but I'm in doubt about my need for a high MP camera.  A camera needs to have a attractive set of features before I upgrade.

Canon General / Re: Photographer Petitions Canon for Left Handed Camera

It probably won't happen since they would have to redesign the manufacturing process to so it, and there likely isn't enough of a market for it to be worthwhile.

Its not as simple as manufacturing, since almost every one of the 100 more or less sub assemblies would be affected, service stations and spare parts would need to be stocked, the cost would be huge.  I also think a adapter would be the answer.

Third Party Manufacturers / Re: One single reason to never buy Nikon DSLR

I have never had a issue with that 10 pin connector.  However, a cheap third party connector from China could be way out of tolerance.  I still have one in my studio, but no longer have the camera.
I've also had some junk 3rd party accessories for my Canon cameras, many of the 3 pin cables are crap.

Before I retired, I was asked if I knew where I could find a left handed phone for Bill Gates, or even someone who would build one for him.  One of his employees has contacted my company thinking that we might know, and I had dealings with many electronics companies around the world. Yes, THE Bill Gates.  I'm left handed but since I only have hearing in my left ear, I use a Right Handed one and had never considered a left handed one.  This was in the early 1990's before cell phones became popular.  Cell phones were Analog then and were not secure.
I have no issue with a right handed camera, and I shoot my hunting rifle right handed, but my pistol I use left handed.  I can hit a baseball left or right handed, but prefer to bat left handed, and cannot throw a ball with my right hand. 
Its easy for me to understand that there are different degrees of left handedness, so some might have a real issue, and its nothing to laugh at even if its not a problem for me.

Lenses / Re: Auto Focus MicroAdjust--Why the Stigma?
« on: January 25, 2015, 08:59:41 PM »
I'm not sure I follow this thread.  I think perhaps the word "stigma" is being used incorrectly in the title.  When I think of AFMA I think of there being a lot of confusion out there about what it is and how it works, even though it's pretty straightforward IMO.

I've also never seen a thread where somebody claimed to send the lens back to Canon for AFMA.  I'm not saying it hasn't happened, $20 says it has - I've just personally never seen somebody claim to do so on a forum.

Many send their lenses and bodies to Canon to have them adjusted.  Canon does not do a AFMA, they adjust the lens and the body if required.  Its expensive.
Some do take their lens and body to a Camera Repair service which does not have the ability to make the internal adjustments, but will do a AFMA for $60 more or less.

Sports / Re: Motion Blur (on purpose) in Sports Photos
« on: January 24, 2015, 11:49:19 PM »
occasionally it works for me to view as long as  its subtle and functional.  Its really difficult to do, I've only seen a very few images that impressed me, and I am a total failure at producing anything I like.  A lot of it is personal opinion and preference.
Sometimes, like last week, there was not enough light, so I had a shutter speed that was not fast enough.   However, I was not trying to show a blur

I have the 17-40 and since you will be using it for landscapes the f4 won't be an issue.  I use mine all the time.  It's a great lens.  The 16-35 f4 is is supposed to be even better overall.

Check out a site like photozone to compare lens performance.  The 18-55mm IS and the STM models have outstanding performance on a crop, better than the 17-40.  The 17-40 fares better on FF than crop.
So, you can do extremely well with a low cost lens.
If you want f/2.8, a 17-55mm EF-s is extremely good, and used prices match the 17-40.  But notice, the 18-55mm IS is sharper, and at the edges, its amazing.!

The fact is that bodies also have a tolerance, so AFMA can be due to a body, but is likely a combination of lens and body tolerances, you are compensating for both.
Different camera models, particularly crop and FF will show a much wider difference with as given lens because a AFMA point is equal to 1/8 of the depth of focus.  That means that it is different for each lens and on different sized sensors as well as body tolerances.

Thanks for the overall feedback.

I agree this is a long way from an ideal study.  If I had wanted to publish in a journal I would of course have raised the bar significantly...  but this is a forum.

Since you made it a point to state that you had engineering expertise, you raised that bar by implying it would withstand engineering scrutiny, but, IMHO, it doesn't.  As a licensed registered professional engineer, I found that comment to reflect poorly on the engineering profession.
There are many reasons for camera failures, and shutters are only one of them.  I suspect, but have no actual numbers that the average consumer camera has well under 15,000 shutter cycles, I've bought two dozen and none of them had nearly that many when I later checked them, and none failed.  Without accurate numbers and information about the camera population, its impossible to put the data into perspective.  If, as I expect, 90+ % of the cameras of a given model have under 15000 actuations, then the numbers do not make sense.  We don't know.
Reliability does indeed involve infant mortality where failures happen more frequently after a new product is put into service.  Usually, electronics is the most affected, but mechanical items suffer from the same issue.
Heat is the big reason driving failures, but cold can be bad as well.  The thermal expansion / Contraction can literally tear things apart in short order.  Product wearout usually happens after a long period of use.  Obviously, vibration and shock can also destroy a item, but heat is a killer.  A camera that is left in a hot car can have its life shortened considerably.
Then, there is the sensor.  They tend to get more hot pixels over time, so a older one will suffer.  There is no information about newer sensor designs, so hopefully, that issue is being reduced.
When buying used, I would have no concern about a camera 6 months old with a few hundred cycles, because the electronics has been burned in, and any mechanical issues should have been found.  The one area where there would be no information is exposure to high temperatures as found in a car on a hot summer day.

Finding a supurb lens on a budget can be tough.  The 28-105mm is one of those, the 80-200 is not.  I've found all of the lenses used that I mention below for $125 or less (Mostly Less).
Upgrading the original 18-55mm lens to the newer 18-55mm IS version is a big upgrade for little cost.
If you can find one of the older 70-210mm f/4 lenses, they can be a good deal.
I have a Tokina 17mm f/3.5 prime that I bought on the cheap, and found it to be excellent.
If you are willing to manual focus, there are a number of Olympus, Nikon, Pentax, etc lenses that can be adapted with good results.
28-XX mm is not a good focal length range for a crop body, so I'd recommend passing it up.
