Software & Accessories / Re: AFMA advice sought
« on: December 30, 2012, 08:39:35 PM »


I bought the Lens something from spyder. Either my eyes are not good enough or....
I have that Issue, I can not see the fine differences once the setting gets close.

1) do you have to buy a new program for each body ( their website asks you to order for a specific body). My camera is a 5D II, but I have and am still borrowing a 1Ds III for the last three years. Hence would I need two payments and two programs for those. The questiens becomes even more pertinent if I finally Get the 1Dx.
 
Your purchase allows you to use FoCal on 5 different bodies.  You can add or remove bodies a limited number of times, which is to prevent users from cheating, but you can have five at a time.

2) does the program do the callibration for you? (Of course you need to set it up and so forth) But will it set the appropriate values for you in the camera, or would you still have to go through with shooting many shots,to narrow the gap down as with the solution i have today?
The answer depends on the camera body.  The 7D and 5D MK II are full automatic, but the 5D MK III and the 1D X cannot have full automatic calibration due to limitations in the Canon SDK.  So far, a way to make the calibration fully automatic for those bodies has not been found.  You have to follow on screen instructions and change the AFMA value manually between shots, otherwise, its automatic.  This actually goes pretty quickly, since they have improved the ability of the software to find the right value with a minimum number of shots and AFMA settings.

Canon has been trying to boost sales for the 2012 fiscal year that ends December 31 2012.  They may well extend or start a new rebate program, but traditionally, the big sales end in December.
 
It all depends on inventory levels and how good of a job they did at getting them down.  I'm pretty sure that we will still see some rebates, but maybe not a big.

EOS Bodies / Re: Does a 39.3mp Sensor Exist? [CR1]
« on: December 30, 2012, 01:17:52 PM »
I'd be suprised if Canon has not built many prototype sensors of various mp ratings.  They are said to be actively pursuing the rear lit technology too, so those will exist.
 
However, I expect that they are prototypes, you don't go into production on multiple sensors unless you are committed to using them, since production startup costs are very high.

@Mt Spokane: Talking rear lit sensors, I guess within three to four years time (1Dx, 5D3 life cycle) we might probably see some (r)evolutionary improvements then. Or will the first outing of such a kind of sensor be presented in a Rebel? The high MP count body might offer an attractive platform as well. So, if I am not totally wrong, high ISO IQ could improve more until 2015. Not higher ISOs, but maybe 51k ISOs equivalent to 25 or 12k ISOs. What do you think?
The patent claims it benefits sensors APS-C and larger, so we should might see it in FF first.
Basically, it will reduce noise, particularly at low ISO, if I understand it correctly.
 
If its going to happen, it will be soon.  In a few years, other processes will be developed.

Speedlites, Printers, Accessories / Re: *EDITED* USB Cable for 5D Mark III
« on: December 30, 2012, 11:20:18 AM »
I've used many USB cables without a issue, my normal one is a 10 footer. 
 
For long lengths, you can get a active USB cable that repeats the signal.  They come in 16 ft, 32 ft, and 64 ft lengths and are inexpensive.
 
There are some here on Amazon.
http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Daps&field-keywords=active+usb+cable
Make sure you get a A Female to A Male, and then use it as a extension cord for the cable that came with your camera.

Lenses / Re: Please help, did I receive a defective lens? 40mm f/2.8
« on: December 30, 2012, 11:14:25 AM »
All the stock of lenses had the firmware upgraded several months ago, a new one will not have the firmware issue.
The lens is a focus by wire, so even in manual mode, the stepper motor will opperate as it focuses the lens.
 
If you have very good hearing, it might sound bad, or, it might be defective.  Return it to Amazon for another.

Extenders don't generally work well with retrofocus lenses.  Thats why they specify using them with a lens of 100mm or longer.  It might physically function with the 50, but you might not be happy with the results.

Technical Support / Re: Mirror fallen out of 5D - self repair ?
« on: December 29, 2012, 03:15:25 PM »
Canon does not just glue a new mirror in, they modify the part that holds it so it won't fail again.  Gluing it yourself is a really bad idea.

PowerShot Cameras / Re: A1200 for $35
« on: December 29, 2012, 11:03:43 AM »
Yes, its a good deal.
 Canon is dumping a lot of the older models trying to reduce inventory and bring in a little money.  They typically do this every year, but cuts seem deeper this year since P&S sales are really poor.

EOS Bodies - For Stills / Re: 1D X FPS limiting factor?
« on: December 28, 2012, 10:42:01 PM »
is there any info on how many pixels per second the digic 5+ can process?
any bandwith specs?
Its not specified.  However, many things tend to be limiting, the shutter speed, the card speed, the processing speed.  In a good design, they all tend to be reasonably close in capability.  For example, a faster processor would eat up battery life and give no benefit, a faster shutter would not help if the processor was incapable of faster speeds, and none of this would matter if Card and internal memory speeds were not fast enough.  .

 ;)

all fine and correct but does not answer my question.


You ask, and I told you its not specified. That means no specs.  Apparently you are hoping someone will fabricate numbers for you?

Paint sticks (Flat black), even Sharpie pens will erase a minor scratch.

The G1X was overpriced.  I bought the deal which included camera and 95000 MK II printer for $399 net(After rebate) from Adorama last fall.  Thats about the right price.  It does a excellent job at that price point, but not at $800.

EOS Bodies / Re: EOS 60D Stock Levels Getting Low?
« on: December 27, 2012, 11:30:41 AM »
Our local Costco stores each have large pallets full of 60D's.  That often, but not always signals that they are being closed out, and that Costco was able to buy out huge amounts of remaining stock at a good price.  If there were 250 of them at  just 1/2 of the 618 stores, that would be over 77,000 cameras.

Mick, I'd recommend Lightroom or DXO. 
Lenovo makes some very tough laptops, Apple laptops are not ruggedized, but very popular.  A lot of users seem to be struggling with the new Apple OS when used with utilities from the camera makers right now.  I suspect that Apple will work out the bugs.
