Pricewatch Deals / Re: Buying Used Equipment on LensRentals.com

As to rental cars, rental companies have been recently cited over and over for not incorporating safety recalls, and they likely scrimp on maintenance.  I'd pass on a used rental car, even though most probably will last for many years.

True that, so I'll put my faith in a good compression test first.
How do you compress a transmission, or air conditioner or onboard computer/  In the old days, a compression test could pretty much tell the issues.
Nowdays, you can't even pull the plugs to test compression with removing half the stuff covering the engine.  The readouts from the computer are about all you have, and they don't tell you if a car was severely abused.  They do have memory devices that record the last XX hours of operation, but only a dealer can access them.

Third Party Manufacturers / Re: 4K 15 FPS
« on: November 20, 2012, 07:58:19 PM »
their target is to record in 4K not timelapse it.
they offer cinema 4K as well at only 12 fps.
its a microsd card limit.
You missed his point.  15 or 12 FPS  will look choppy like a time lapse video.  If you like the old time movie look, its usable.  Even 24fps is a bit choppy.

The lenses are heavily used, but well maintained.  Each lens goes thru a sharpness test when it comes back from a rental, and its pretty well checked out.
The lenses are going to have plenty of signs of a rough life, the paint will be scratched, and other cosmetic damage.
However, you will almost certainly get a lens in better working condition with no decentered elements than what you may get buying one from Craigslist.

Live view is at its best for studio portraits where it is used while the camera is tethered to a computer.  I use it extensively that way.
It is also useful for manual focus lenses, since you can magnify 5 or 10X and get more accurate focus.
I'd guess that only 1 or 2% of users use it that way.

Lenses / Re: Is the EF 800 f/5.6L IS Due for Replacement? [CR2]
« on: November 20, 2012, 01:22:03 PM »
1993 EF 1200mm f/5.6L USM
That lens has been out of production well over a decade, and the number of units in likely in the 10's
I've always understood that no 1200mm EF lenses made.  The only ones were reworked 1200mm FD lenses. 
Wikipedia
The EF 1200mm f/5.6L USM is a professional L-series lens, that is now discontinued.[2] The lens was first developed for the Canon FD mount, although never marketed until after Canon had transitioned to the EF mount. According to a Canon USA representative interviewed in 2009, the lens made its first public appearance at the 1984 Summer Olympics in Los Angeles; Canon had shipped five copies of the lens for media use at the Games. All of the FD 1200mm f/5.6L lenses were eventually shipped back to Canon in Japan. Later in the 1980s, these lenses were converted to the EF mount.[3] The official site of Canon competitor Nikon implies that early versions of the Canon 1200mm lens (with a built-in teleconverter, a feature not included in the final production lens) were also used by photographers covering baseball games, including the very popular high school tournaments, at Japan's Koshien Stadium.

Pricewatch Deals / Re: Black Friday-> Red Thursday? (FS VIP Sale)
« on: November 20, 2012, 01:15:12 PM »
Lots of pre-black friday sales right now.
Future shop was chased out of the USA, they did so much  bait and switch that the public just ignored them.
When I lived in North Toronto, I used to go to the one in  North York on Yonge I had the same experience, they never seemed to have a low price advertised item.
I hope they are different now.

EOS Bodies - For Stills / Re: TV MODE
« on: November 20, 2012, 12:13:33 PM »
Can anyone explain to me why when I set my 5D II to TV mode, set a shutter speed of say 1/800 and take a picture it adjusts the shutter speed? Shouldn't it stay where I set it? I had an epic wildlife photo today but missed it because my camera adjusted my shutter speed. I was shooting in TV mode at 1/800 ISO 200 100-400 4.5-5.6 Lens and when I took the shot it adjusted to 1/20? ??? ? I am obviously missing something. Thanks for the advice in advance!!
The image would be black at those settings.  You would not have had anything at 1/800 sec but black.
You likely needed ISO 12800.
If you look thru the viewfinder or top lcd display, you will see the aperture flashing to tell you that you can't get the image at that setting.

EOS Bodies - For Stills / Re: 5D mark III or 7D and 5D mark II
« on: November 20, 2012, 11:57:58 AM »
I sold my 7D and 5D MK II and bought a MK III.  The 7D no longer got any use.  I had planned to use it in focal length limited situations and for product photography, but the MK III handles that well.
I bought my wife a 1 GX whis has been pretty good at product photography, but can't match a tethered DSLR.

As Mt Spokane wrote, it's against federal law to resell a used camera as new....

Mt. Spokane, if you don't mind, would you please link an article to the aforementioned law.  I tried searching for it, but came up blank.  Thanks in advance.

Sony wants to sell used items as new though.

The last refurb sale was on all lenses. Naturally most Ls were "out of stock", but they had a few.
They have had two sales since, one for 30% off low end lenses, and a $50-$100-$150 sale based on the lens price.

EOS Bodies / Re: 5D3 lens correction profiles - only jpg?
« on: November 19, 2012, 11:31:54 PM »
Does LR4 not recognise that metadata?
No, it does not recognize if the lens correction is turned on in camera.  It does not see the lens correction data that DPP adds to the CR2 file.
LR4 has its own lens correction data which can be applied automatically, or just for images you want.  It is not saved to the cr2 file.
This might be stupid question so let me begin by apologize. I am using LR4 and applying the lens correction profile there for my RAW files. I shoot with 5D3 and L lenses. Would I need to do something else that you're talking about for lens correction or shouldn't this be enough? I am happy with the end results at least.
The Lightroom corrections are pretty good, so are the DXO corrections.  The Canon DLO corrections are said to be able to do a slightly better job, but you must use DPP and download the lens correction profile.  Its only available for certain lenses, and not for non Canon lenses.
If you save the corrections to the CR2 file, it gets huge, so its best to save the finished image as a jpeg.
I also just use Lightroom.

Technical Support / Re: Sandisk Extreme Pro behaving very unusually.
« on: November 19, 2012, 07:39:50 PM »
You may have a bent pin in the memory card connector in your 5D MK III.  That has happened to the 5D MK III more frequently than usual.
Get a good light, and magnification, if necessary, and check that one or more of the pins is not bent over flat.

I'm also waiting for the 20% off sale.  However, I have no idea as to when it may come.  Canon has been having deep discounts on a few power shots, but the general 20% off sale on lenses hasen't happened recently.

1. Basic lens correction
Corrects for vignetting and chromatic aberration. Supported in-camera for JPEG or through DPP software as post. The same correct JPEG is also embedded to RAW, if shooting in that mode, as well as being flagged.

2. Digital Lens Optimizer (DLO)
Supported through post-process only through DPP software and with RAW files (no JPEG). Optimization data is non-destructive and appended to the original RAW file, which may more than double in the size. Note, it's not possible to use both 1 and 2. The two are mutually exclusive.


OP and Neuro was referring to #1.
Thanks for clarifing that.  I am always happy to learn.  I was under the impression that the in camera correction was the same as DLO.
