Video cameras can record at lower levels of light and still have decent looking images.  Those noisy images flipping by at 30 fps look pretty good.  Film makers have taken advantage of this for years.  The Canon 5D MK III videos look much better than the stills at extreme high ISO settings.
 
Don't assume that still images will be usable at the same high ISO levels used for video.

I bought a high end Benro tripod a few years back, and now the rubber is falling off the twist locks.  I called to order replacements and was told that it was gray market.  Since I still had the original box, I took a photo with the USA distributor label attached.  Then, the support person said he didn't know that they had imported and sold them.  The bottom line:  No parts of any kind are available from Benro.  The rubber grips are a minor item, but if a needed part fails, its a $450 piece of junk.
 
I'd stick with a company that supports their products.

I've been using the EOS utility for many years to shoot remotely.  I also use DSLR Remote by Breeze.
 
Its great.  The issue is focus speed.  While you can use the conventional phase detect, I prefer contrast detect because its silent, no mirror clacking up and down.
 
I'm looking forward to FF with the next generation of dual pixel technology for fast focus using live view.

Software & Accessories / Re: Protecting foam on monopod / tripod legs
« on: April 23, 2014, 06:14:32 PM »
The foam is there to protect the legs, so will this lead to protecting the protection that protects the protection for the foam that protects the legs?
 
I think a neoprene wrap is a good idea for replacing the foam once it dies.  Some who do not have the foam protection for their tripod or monopod buy closed cell foam (for insulating pipes) from their local hardware store.  It comes in multiple diameters and I've seen gray and blue colors.  A wrap of gorilla tape will protect your $1 investment.

The Focus screen is made of a easily scratched plastic that also takes and retains fingerprints.  I don't recommend touching it unless you are ready to buy a replacement.
 
Blowing gently is OK, but you are just moving dust from one place to another.
 
I've never heard of anyone cleaning the AF sensor, dust on it does not show in the images, and is very unlikely to affect exposure, so the risk versus improvement ratio is pretty high.  Same for the sub mirror.

I just checked my other lenses and anything purchased prior to 2011 don't report serials properly in Bridge - 100L, 85L II, 70-200L II, etc.

The only lens that relays serials properly is the 40 STM, which I picked up most recently bout a year ago.

I'll have to try mine.  I didn't think that the lens serial number has ever been in the metadata.

Software & Accessories / Re: Lots of CF or Tablet+OTA cable?

I use cards that are 64 GB or larger.  Do you have a 1TB tablet?  If so, I'd use it rather than ten 64 GB Cards.

Canon General / Re: Canon Loyalty Program question

Generally, if its not on their website, then its out of stock.  CLP Cameras and Lenses come from the same inventory.
 
Conversely, if its shown in stock on the refurb website, it may still not be available thru CLP due to low inventory levels.
 
Canon Price Watch shows the inventory levels for Cameras and Lenses, so its a good resource to see approximately how many are available.
 
Right now, it shows out of stock.  There will likely be more added in a week or two, so setup CPW for a automatic notification e-mail.

Lenses / Re: Bought the 300mm 2.8 ii and think its huge
« on: April 20, 2014, 11:07:53 PM »
I had a old Canon 600mm f/4 non IS, and one of the original Nikon Autofocus 300mm f/2.8 lenses.  The Nikon 200-400mm f/4 seems like a light toy compared to those. I have not used the 300mm f/2.8, but expect its a similar size.
 
For me, that's too big, I'm downsizing due to my hands getting weak, I sold my 1D MK IV and my bigger lenses.  The 100-400mmL and 70-200 f/2.8 are as big as I can handle.

Photography Technique / Re: What if we were still shooting slide film?
« on: April 18, 2014, 07:56:57 PM »
I virtually never use burst mode.  I was used to timing my shots and looking for things like closed eyes.  Occasionally, I see someone close their eyes just as I shoot, so I quickly open the shutter a 2nd time.
 
Still, I do take a lot more digital photos than I did with film.  The cost of film was high.

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.

Lenses / Re: What has become of the long-rumored Canon 50mm IS?
« on: April 18, 2014, 12:16:44 PM »
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: April 18, 2014, 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.

Canon General / Re: "MAP" pricing....How long will it last????
« on: April 18, 2014, 01:54:48 AM »
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.
