EOS Bodies - For Stills / Re: Reikan FoCal Pro with 40 STM
« on: January 13, 2013, 06:14:57 PM »
But looks like for you running focal is a moot point as AFMA from -1 to 5 gives the same results.

Nothing wrong with my set up.  I used the same setup to shoot 20 shots of a newspaper and the AF was consistent across almost all of the 20 shots.  This issue is with focal and their change in algorithm.

Thats normal.  There is very little difference in sharpness at the top of the curve, so being off by a couple of points with AFMA doesn't really affect sharpness, and can't be seen at the scale of the plot.Some lenses have a sharper peak and some are flatter.
 
When you look at the actual numbers returned at those top points, the +2 point of the curve is a little sharper, but not enough to worry about.  Most people could not see the difference.
Here are the numbers:
AFMA= -4  527
AFMA= -1  852
AFMA= 0   853
AFMA= +2  872
AFMA= +3  865
AFMA= +4  818

Here is the part I read.
"So, when I try to resell it, it is obvious that it is a refurb.  How much does this lower the resale value and will I have a harder time reselling?"
 
Sorry if I mis-intrupreted what you were trying to say.  Don't worry about the hole in the serial number, just expllain its a refurb.

EOS Bodies / Re: EOS not good for NASA?

It makes sense to pick one brand of Camera, after all, you want all your lenses to be interchangable.  That doesn't imply that Hasseblad, Canon, sony or any of the others are not good, just that Nikon was selected, and now that the space station is full of Nikon lenses, that will not change, no matter how good other brands might be.  The cost of a camera is nothing compared to the cost of sending all those lenses into space.

Lenses / Re: 17-40 vs 16-35, which one got the mojo ?
« on: January 13, 2013, 01:01:04 PM »
The photographer is going to make 99% of the difference to the image, maybe more, so the remaining 1% is what you are dealing with, no matter what lens you buy.
I could never really warm up to the 17-40mmL even thouugh it was a fine lens and sharp.  I recently bought a new 16-35mmL, but do not yet have enough experience with it to pass judgement.  Overall, I just don't seem to like ultra wide.  From what I've seen, the new Zeiss 15mm might change my opinion, but I can't afford it for the very few ultrawide images I take.  I did buy a Rokinon 14mm and found it to be worse than a Coke bottle.

EOS Bodies / Re: Auto_focus Acting Up
« on: January 13, 2013, 12:53:51 PM »
I've had that happen on many cameras, it sometimes took me a while to determine what I was doing to cause it.  The 5D MK II was particularly bad because the depth of field button falls naturally under my left hand, and I sometimes pressed it.  The Nikon D800 had a similar issue, there are two buttons that the fingertips of my right hand press when holding the camera by the grip in my right hand.
I'd suspect its something simple, but it certainly could be a problem camera.  Its not going to be the lens or contacts.

EOS Bodies - For Stills / Re: AF Speeds on Different Canon EOS Bodies
« on: January 13, 2013, 12:47:21 PM »
There is some evidence that the new bodies like the 5D MK III focus more accurately and consistently, at least with the center point (with some of the newer lenses).  Certainly, FoCal users find it more consistent than a 5D MK II.
No one knows exactly why that is.

Why would you try to conceal that it was a refurb when you go to sell it?  Are you planning to claim you bought it new? 
I'd be much more inclined to buy a camera in its original packageing with a copy of the original purchase receipt, so without that stuff, the resale value will be less, depending on the number of actuations and condition of the camera.

HTP is going to change the look of a severely backlit image.  One way to help out with this type of image is to light the subject with a flash and better beamer.  The DR, particularly at high ISO's is very limited.

Software & Accessories / Re: Reikan FoCal not compatible with Win 8
« on: January 13, 2013, 12:26:41 PM »
I tested it on my Windows 8 as well.  Not officially tested yet with Windows 8 does not mean that it is not compatible.  Tons of software runs fine with windows 8 but is not officially supported yet.

Slow week at CR?  Yet another CR1's to pass the time?  ;)
What happened to the Jan 8th 35L II and 14-24L UWA from last week?  :P
You have been playing the same tune over and over.  Perhaps you think that you can force Rumors to be true, or that only rumors that are guaranteed to be true are posted.
If you can't handle rumors, you need to stop reading them and then complaining that they are  ... Well, just Rumors.

Instead of instructing me that this is a rumor site, which I fully understand, you could perhaps learn to read what the tongue-in-cheek or tongue sticking out icon  :P means...I hope I am allowed to comment if a Rumor goes Dud and the original short comment was not a severe criticism in any case.

Unless CRs policy is to check with you first. Would your busy schedule with 90000 posts here allow for that time? :P
Its fine to point out your concerns, its posting the same thing over and over like a broken record is the issue.

I suspect that Canon feels that their strategy is more successful.  At a time where camera sales are hard hit, Canon is doing relatively well.  Companies tend to stick with what works for them.

No. 
Lenses, not bodies are where your investment should be.  Saving $500 on a body is peanuts compared to $!0K - $20K in lenses.  How many would want to invest that much in lenses from a company that may possibly go away in the coming year or next.

My 40mm worked well with Focal.  Somethings wrong with your lens or your setup.

Third Party Manufacturers / Re: WW2 Kodachromes 4x5's
« on: January 12, 2013, 02:52:15 PM »
I'm glad that the Kodachrome images kept their colors so well.  I inherited many film negatives from my parents, and the old 120 Kodacolor(not Kodachrome) negatives are badly faded away, even though stored in light proof boxes and envelopes.  The B&W ones are fine, as are my Kodachrome slides from the 1950's and 1960's.
