Third Party Manufacturers / Re: Phase One Mirrorless MF Camera in December!
« on: November 16, 2014, 01:16:49 AM »
I'll put money on Canon working on a mirrorless that has the look, feel, and build of a 5D Mark III.  Electronic viewfinders have come a long way.  Want a burst rate of 20 fps?  No mirror to limit the fps.  No mirror bounce = sharper images.  Need one heck of a buffering system though.  There are things mirrorless formats can do that DSLRs can't.  The next year or two might prove interesting.

I don't think they will, simply because I'd love to have one, and they never seem to take my advice.  ;)

EOS Bodies - For Stills / Re: Card images failed transfer error on 5d3
« on: November 16, 2014, 01:12:57 AM »
I have a recurring problem in my workflow where i transfer images from cf to sd in camera, but the camera gives an error about card transfer history.

This seems to happen after i format both cards in camera, and after a while it goes away and i can again transfer images in camera.

The trouble is that when i am on location with my ipad, i have no way of reviewing the images on a larger screen. The ipad only takes sd, and i only shoot to cf.

Does anyone know a solution to this problem?

Shoot raw to the CF and jpeg to the SD card.  I often do that.  It provides a backup and I can quickly get jpeg images to review.  Since you have the capability, try it.  I use a 64GB SD card, and since jpeg files are smaller, it holds a lot of images.

Can you provide more detail?  Does it take the 400 black shots by taking just one, pulling out the card and reading it, or is the shutter continuously opening and closing without anything pressing the shutter?  Are mages numbered before or after the good shots, or interspersed?
 
A sticky shutter switch is a possibility.  The shutter button depresses a switch in the camera ut is not physically connected to it, so the switch might be sticking, but the shutter button pops up normally.
 
If its a stuck shutter switch or one that occasionally sticks, it will have to be serviced.
 
Here is a link to a person who was using a 2 second delay and the sun hitting the IR receiver was tripping his shutter.  It doesn't sound like your issue, but is interesting to read.
 
By posting the issue on the Canon forum, you may get a response from Canon, probably one that says to send it in.

I've seen posts where people were asking for an MF mirrorless, but at $43K + lenses etc., I can't see it being sold in the thousands, nor it giving any curry to the Sony A7's.

Now I know that mirrorless cameras sell for more than an equivalent DSLR, but this is just ridiculous.

That includes a $5500 Rodenstock lens.  The price for the high end model will double. 
 
My point was, if a mirrorless can be made for a MF camera, we should see Canon coming out with one for FF bodies.  The question is- How much will you pay to remove the mirror?  It ought to lower the price, but we know better.

One other comment, this is not actually a new camera, rather a combination of existing pieces from two manufacturers and sold as a kit that is adjusted and shimmed for proper registration of the lens and back.  It might be manual focus, I am not that familiar with the pieces.
 
The mirrorless caught my eye, but it might be just salesmanship.

I can imagine that getting rid of that huge clunky mirror would be welcomed.  Hopefully, it would use the same lenses and body, just minus the mirror.  Its not a sports camera, so lightening fast AF is not required.  In a studio, a LCD monitor will work fine to compose.  I'm not sure what options might be coming for landscape photographers who work in the daylight.  Perhaps a EVF?
 
You can probably get one starting at $43,000 for the beginner model ;)

Canon General / Re: Forum Decorum....Deshmorum?
« on: November 15, 2014, 04:40:51 PM »
I think this is an interesting thread.  Let's be honest... we humans love to see a good fight.  Esp a hair pulling, nail scratching girl fight.  But any fight will do.  We like to see gladiators in all their glory.  We like to see NASCAR races with big firey crashes.  We love action movies with lots of mayhem and action.

Face it, we're just wired that way.

So when things get heated in forums, regardless of the topic, we just can't resist the urge to get a punch in.  It requires a certain level of maturity and discipline to resist that urge.  I've always found it to be a fascinating thing that Internet Forums provide detachment and anonymity which allows us to view arguments from a distance, take our time, maintain calm and decorum and avoid the impulsive emotion laden responses that in-person confrontations can provoke... and then many folks still act irrationally anyway.

I'd agree on that.  All the photography forums have to deal with it, most of them are a lot tougher than CR. 
 
Its fine to state your opinion about a subject, but name calling to belittling a person because of their beliefs turns into a free for all pretty fast.

Lenses / Re: If only Canon made this lens

Canon EF 500mm f5.6L IS.

For bird and wildlife photographers who can't afford the f4.
Like to regularly hand hold their equipment in the wild
A sharp prime weighing less than a 300 f2.8
Enough reach without convertors and their associated drop in AF speed and IQ

Costing $2.5k

Just a thought
 

There are lots of photographers who would like it to happen.  The reality is that it would likely sell for $3500, and few would pay that much.  It would be a very large lens, about the size of the Sigma 150-600 Sport, which is smaller only because its f/6.3.  I also doubt that it would weigh less than the 300mm f/2.8 due to the additional metal in the longer length, and the thicker metal needed to withstand more bending stress.
 
One of the issues I had with my 400mm f/5.6 was its length and its long MFD.  A 500mm would be longer and larger in diameter.  A zoom has a advantage in that they are shorter when zoomed wide, and can have close mfd's without getting excessively long while zoomed wide.
 
If Canon could put one out for that price, I'm sure there would be many buyers, I'd prefer a 200-500mm zoom that would be shorter when stored.  I could live with f/6.3 as well, but Canon seems to have a limit at f/5.6, and won't send false exif info to a camera just to get around the limitation of the cameras.

I don't go into any menu.  I plug the USB cable into the camera and PC then turn on the camera.  I go to "my Computer" and open the files.  I copy those files to a folder on the Hard Drive.  I started doing it this way when I had a card reader fail.  Since it seems to be a much faster transfer, I didn't go back to a reader.  Plus, if you don't remove a card from the camera, it's less wear and tear on the pins- or worse, a bent pin.

A 5D MK III has space for two cards, a CF and a SD.  You can copy images from one card to the other.  There is no pc and no usb involved.

Pricewatch Deals / Re: Refurb S100 today $109
« on: November 15, 2014, 03:48:50 PM »
They are very good for the right people.  I bought the wife a S95 years back.  It struggled indoors and colors were a issue.  The by far biggest issue we both had was pressing the tiny controls.
 
I bought a too cheap Nikon 9700 P&S ($125) for her to take horse riding, I figured it was a nice enough camera, and if it got busted up, it wasn't the $800 loss that my G1X would be.  It turns out much to my surprise that she likes it and takes it everywhere.  I was going to sell it when she returned, so I guess the G1X is now mine.  I use it quite a bit.  For serious photos, the 5d MK III is miles ahead of either one.

Lenses / Re: Advice needed on possible 100-400 L Lens Trade
« on: November 15, 2014, 02:31:00 PM »
I'd echo the above, check the zoom action is smooth and doesn't stick/jump. Also look through the viewfinder when doing so. I fear my 100-400L I had since new is wearing out from heavy use, and the zoom isn't smooth any more.

I previously had a used 35-350L which is also pump action, and that suffered even worse. At least I got that from a dealer so I could return it.

Just as soon as it shows any signs of sticking, send it to Canon.  It starts by getting dirt in the bearings and, if caught early can be cleaned and lubed.  Later, it becomes a mess.

You are in the wrong menu.  To "transfer" images from CF to SD you need to use the option "Image Copy" (under PLAY2- [the blue menu])
Image Transfer is for transfering images to a PC.

Right Answer, if you are not using the copy function, see pg 277 of your manual.  Since it works sometimes for you, I wonder if you have been using the coppy function on occasion.

As far as values go, they are pretty equal.

Be wary of a used 100-400.  Try it first.  Some of the early ones were lacking in sharpness.  They weren't bad, but later ones are said to be better.  I've had both early and later, and noticed the same thing.  A second issue to watch out for is the locking ring that holds the lens at any focal length.  Unless it operates smoothly and lets the lens telescope smoothly, skip it!  Its not a matter of lubrication, it loses ball bearings and must be replaced at a unusually high cost.

Used 100-400L's without box sell for about $800, maybe a little more on ebay, and the seller has to pay ebay fees out of that.  I might be able to squeeze $1100 out of my near mint lens that is in excellent condition and is sharp.  It still has the box and other stuff.

I paid $1610 for it in 2010.

Evaluation with SIGMA’s own MTF measuring system “A1”
 
 
 
 
 
We used to measure lens performance with an MTF measuring system using conventional sensors. However, we’ve now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA 150-600mm F5-6.3 DG OS HSM will all be checked using this “A1” before they are shipped.

Did you just discover this?

You might also do some checking and find that no one actually knows when they might ship, or many other details.  It does not exist except on paper.
 
If you look for a weight of the lens, it is tbd.  You can't weigh the paper and come up with anything meaningful.  I'm sure they know within a few ounces, they just don't have a finished lens to weigh.  All the photos are of prototypes, and might not even be functional.
