Just what specifically would you enhance?  Bokeh is not a well defined term and means different things to different people.  It is not something that can be measured, its subjective.  First, a method of measuring it would be needed, and so far, no one has one.

A lot of people are wondering what all those employees a Canon have been doing.  Perhaps they have too many high paid managers and bookkeepers that block everything.  Big corporations tend to have issues like that, and it takes a changing of the guard to overcome stagnation.
 
However, for a corporation, the bottom line is the important thing, and Canon is doing much better than the competition who are spending a lot of money releasing new cameras that sell in very small quantities to a limited number of people, and make no or little profit.  Canon's bread and butter is mass production at low prices, and they stick to what works.

Lenses / Re: Sharpest EF Lenses (according to DxO)
« on: Today at 12:08:28 PM »
First, the ratings only apply to a specific camera body.  Certainly not across brands.
 
People tend to look at the numbers but misunderstand what they mean.  They are forever comparing ratings from one brand to another, a 12mp camera rating to a 32mp rating.  The DXO ratings cannot be used that way.
 
Sharpness (Acuity) is far from the only quality of a lens, in fact, most lens reviewers measure contrast (MTF).   DXO's score, unfortunately does not tell us a lot about a lens, and it is not a measure of sharpness.  Certainly acuity and MTF are factored into their score, but it is incorrect to use the DXO overall number and say that represents sharpness.
 
What factors in to their rating?   - They say:
 
"
The DxOMark Score considers the overall performance of a lens plus its performance when used with a specific camera body.
   
Do they measure coma
What about Autofocus accuracy or speed
What about IS
 
 
 
Their is a lot of improvement that needs to be done in their ratings, several times they have been called out for totally wrong ratings, and after defending them, they silently updated them to correct them.
 
I would not put much if any value in their ratings, since they seem to be unreliable, and use undisclosed weightings that often do not seem to match the real world values that other reviewers take into account.

Yup, Happy Birthday.  We appreciate your posts and help.

Our local dealer says his Markup for Canon runs 7%.  There may be a rebate for meeting sales targets, but a small dealer can't sell millions of dollars worth a month.
 
The salesmen are all photographers and give good advice.  I buy from them frequently, and from Adorama / B&H for something they can't easily get due to manufacturers requiring large purchases.
 
I've found that they can get cameras and lenses from Canon even when the big stores are out, so Canon does take care of small dealers.

Canon General / Re: 5 Reasons you Need a 50mm Prime
« on: Today at 01:45:38 AM »
I've bought 50mm lenses by the dozens over the years, I resell them, but have little usage.  The focal length does not work out for me.

I use the 1900mAh, it isn't a case of "getting away" with them, they are superb batteries that in my opinion offer the best results re longevity, recharge cycles, output and cost.

Been using them for years and have never looked back or wished I had gone for the higher capacity.

After years of use, every one of the 32 or so eneloops still work fine and hold a good charge.  My other NIMH batteries have dropped like flies.

EOS Bodies / Re: 700D card advice please

Format the card with a computer and see if the camera has any life at all.

White will reflect the sun rather than absorb it, keeping the camera and lens cool, so hot climates like ...  OOPS, Whats wrong here???

Canon General / Re: "MAP" pricing....How long will it last????
« on: April 16, 2014, 10:04:00 PM »
I haven't seen Canon changing its policy on the Minimum Advertised Price.  The Policy allows authorized Sales, so we can see a temporary price reduction when Canon announces a sale.
 
Canon has stated that a dealer can sell for whatever price he wants, he just can't advertise below MAP.  A person can call a dealer and negotiate a price lower than MAP without breaking Canon's rules.
 
Sony has had a MAP for at least 50 years, and have enforced it very strictly, they do not allow for privately negotiated prices and come down hard on violators.
 
B&H, Adorama, and some others have found ways to get around MAP.  They only show the actual selling price during checkout.  Then, photography blogs pick up the deal and post it online.  I'm sure that the dealers let them know.
 
You will see some ebay sellers selling below MAP, but they are usually not authorized dealers, they don't buy from Canon, so Canon has no leverage over them.  They negotiate purchases from Dealers who are overstocked, but need to keep sales volume up.  No violation of MAP there.
 
Back in the 1960's, Canon, Nikon, Pentax, etc had very tight price controls, and the US Government helped them by seizing any gray market imports as they came thru customs.  Once again, clever people found a way to avoid this.  There were two common methods used by Hong Kong sellers.  If a logo could be easily removed, it was pried off and the camera and logo were sent separately.  If it was not a removable logo, it was painted out with a color to match the camera.  This allowed people to import for half the price of a US model.  Eventually, the government got out of the gray market seizure game, and competition drove prices down.

Lenses / Re: Canon 135mm f/2.....Is this normal?
« on: April 16, 2014, 12:11:19 PM »
Mine doesn't do it on my 5D MK III.  It might be time to send it in for a tuneup before something serious happens.  Failures always happen at the wrong time, so a early warning should not be ignored.

It looks like lots of people got good images.  It started out hazy here, and degenerated into a overcast, so I gave up.  The night before was clear.

Canon was never a subsidary of Bell and Howell, but they were marketed by Bell and Howell in the USA.  Superscope marketed Sony in the USA, but Sony was not a subsidiary of Superscope.

Photography Technique / Re: Tomorrow's eclipse
« on: April 15, 2014, 02:29:00 AM »
I started my imaging sequence with BackyardEOS about 10 minutes ago. I couldn't see it, but my camera picked up the first bit of the eclipse before I could see it with my naked eyes.

I'm using a tracking mount, so my settings once we get to totality will probably be much different than most. I started out at ISO 100, 1/250th, f/8 w/ 600/4 II. That pushes the histogram to the right with my 7D, but not too far that the highlights blow out. The current part of my imaging sequence has dropped to 1/125th second now, and it'll drop to 1/60th about the time the moon is half-eclipsed...not yet sure exactly what settings I'll be using once the moon is fully within the umbra...

 
It started while I was still fooling around getting my camera setup.  Its set to take a shot every 9 minutes, I'll adjust the exposure in a bit.
 

 
Yes, its all manual, and a lot of skill is involved.  I will be happy if just a few shots come out.  I'm not going to stay up all night fiddling with it.

There are FOUR total lunar eclipses occurring over the next two years. This is a very rare event. It's occurred twice last century, and before that it had not occurred for many hundreds of years. After this, four total lunar eclipses will not occur again for hundreds of years.

Tonight is the first of the four. It starts at 1:58pm ET, 11:58 MT, and 10:58 PT. If you are planning on photographing the first lunar eclipse this year, share your photos here!

I'm aiming to get a full sequence of the entire eclipse, from the first penumbral dimming through totality and ending at the point the moon moves out of the penumbra (for me, that's from 11:58pm through 3:30am.)

For more details, see here: http://www.mreclipse.com/LEdata/TLE2014Apr15/TLE2014Apr15.html
For exposure tips, see here: http://www.mreclipse.com/LEphoto/LEphoto.html

 
Good Luck.  We've been having clear evenings, until tonight, that is.  There are supposed to be breaks in the clouds that will let a person view the eclipse, but photos might be a problem, since it may be a short window before the storm hits us early AM.
 
I went out last night and tried several exposures, and verified a clear view was possible.  Today, I pulled out my seldom used TC-80N3 and set it to take a image every 5 minutes, so I'll go out and set the camera, and just let it run, snapping a image every 5 minutes until its over, or I wake up tomorrow morning and turn it off.
 
I'll have to use a fairly wide angle lens to do that.
 
BTW, The next Tetrad happens in 2032-2033 which is 20 years from now, not hundreds of years.  There are eight Tetrads happening in the 21st Century.
