Lenses / Re: 1.4 TC III vs 60D, Is this test accurate?
« on: April 02, 2013, 01:54:43 PM »
A given lens will always appear sharpen on FF than on a crop camera.  Check all the lens review sites.  Even a 5D classic will produce sharper images than the best Canon crop.
 
DXO also has a useful function where you can see this easily.
 
Check it out on different bodies, the score is always higher on FF for a given lens.

Lenses / Re: Fingerprint "investigation"? (ef 35mm f/1.4L)

Try using this to search the serial numer of the lens

To show if anyone had used it (and posted to the net before)

How??  Lens Serial numbers are not in the EXIF Data.  The site looks for camera serial numbers.

EOS Bodies - For Stills / Re: 5D2 refurb or new 7D as backup to 5D3?
« on: April 02, 2013, 01:31:10 PM »
I've owned two 7D's, two 5D MK II's and two 5D MK III's.  My 7D was mostly useful as a studio camera with good lighting, or outdoors with bright lighting.  It suffered at high ISO 800 or over, but could be used at 1600 or even 3200 if you were immune to noise or used a lot of NR.
 
I always preferred my 5D MK II to the 7D's.  Finally, I sold the 7D's and bought a used 1D MK II.  What a improvement that made. 
 
The 7D was certainly a good crop body, it had some significant good points in adequate light and suffered in low light.
 
 
BTW, you need only look at the resolution scores at Photozone, DXO, or any lens review site to see how much sharper FF images are than images from a crop camera.  Even a old 5D classic will out resolve every Canon crop made including the 7D when tested using the same lens.  The reason is that FF cameras are not as demanding of a lens as a camera with a small sensor.  Just because a crop uses the center portion of a lens does not overcome the FF advantage except for vignetting.

All lenses have tiny scratches on the contacts.  This is because they are mounted in order to test them.
 
However, fingerprints should not be there.
 
As noted in many posts on this forum, only buy from Amazon, or from a major company selling on Amazon like Adorama or Onecall.  Watch out for third party sellers who may be picking up returned equipment from other dealers and selling it as new.  Verify that they are authorized Canon dealers.
 
If the price is much lower than the major dealers, beware.

The 40D is a very nice camera, I've had five of them.  I'd consider buying another if the price was right.  $200 - $250 is a good deal if its a nice low usage body.  The problem is that on our local Craigslist, prices are silly.

EOS Bodies - For Stills / Re: 1DX Does not wake up
« on: April 01, 2013, 07:18:36 PM »
I'd call Canon.  It might be a bad shutter button switch, or something simple.
First, install the latest firmware and do a camera reset.  Sometimes a combination of settings can cause a issue, particularly if a camera reset is not done after a firmware update.

From his post. 
 
(But one important HINT:  It’s NOT a camera… which makes it very interesting to thing:  what could make almost EVERY film maker out there interested in this new technology, regardless of what they shoot, regardless of budget… that’s NOT a camera.  And yes while I realize I’m posting this on April 1, this is absolutely not an April Fool’s joke.)

Lenses / Re: Is my 24-105mm f/4 L unreasonably soft?
« on: March 31, 2013, 05:54:32 PM »
Something is wrong with the curves, a lens always loses sharpness above f/8.
 
However, lenses with decentered elements do exhibit strange curves.  That's one quick way to spot a lens that needs adjustment.
 
This are some typical  curves.  They doesn't go above f/11, but resolution continues to drop off slowly as aperture increases due to diffraction.

Lenses / Re: Tamron 24-70 f2.8 or Canon 24-105 f4 ??
« on: March 31, 2013, 05:46:33 PM »
I would not pay for a wide aperture lens to use for landscape photography.
 
Very small apertures are used, and at f/16, diffraction is the limiting factor, lens sharpness is not a factor.  Distortions and CA's also are reduced.
 
My first choice would be a Tilt-Shift lens, to allow more depth of field without stopping down to extreme small apertures.  They can be had used in the same price range, but are manual focus.  Pretty much any focal length will work, you don't need ultra wide.  A 24mm TS would be excellent, but so would the 90mm TS-E
 
As a alternative, a 17-40mm L is excellent when stopped down, and relatively inexpensive.
 
Invest in a good tripod and remote release, and don't spend a ton of money on the wrong product.

Lenses / Re: New or Refurbished Lens?
« on: March 31, 2013, 02:25:27 PM »
They are back on sale again and a much bigger selection than a few days ago. I own several refurbs as well, always look there first because prices are usually better when they have these sales.

I had just checked last night, and now the lenses I'm interested in are sold out :-[
 
I just ordered a 24-70MK II, so I will have to pay for it before buying more.

Thr refurbs are generally like new and perfect.  I've bought several of them.  They had 15% off last week, but the next sale may not happen for a while.
I'd also check Adorama or B&H, their prices are sometimes lower for refurbs.

Hey Mt Spokane,

Thank you for your rapid response, I've always enjoyed reading what you have to say on the forums. I went ahead and downloaded the images through EOS Utility, simply because I need to get todays shoot out mucho pronto. I think I'll invest in a card reader. My computer has one built in, but the CF slot is the only one that has NEVER worked (go figure). Ultimately, I'm just going to go through with a card reader.

Thank you again,
-Tabor

By the way, are you in Washington?
Yes, I live on the flanks of Mount Spokane, 20 miles North of Spokane, Washington.

Third Party Manufacturers / Re: New sensor doubles brightness

Thank you both. Sorry it took awhile to get back on this.

I got the Zacuto Z-Finder Pro EVF, which is pretty amazing, btw. I can attach it to my shoulder rig using a simple $40 Pearstone articulating arm. But for handheld shooting, I will need to get a Zacuto Gorilla Plate and mounting frame. They ain't cheap, but as I mentioned... I'm not mucking my camera with adhesive. It should pay itself back in used resale value.

Interesting.

So, if you buy the view finder, you have to buy separately the apparatus for attaching it to your camera?!?!

Geez, for the price of that thing, I'd think all the mounting hardware would be included..?!?!?!

 :o :o :o :o :o :o

C

I don't know where he bought his, but the baseplate should have been included.
 
The Z-Finder Pro 2.5x for 3.2” Screens includes:
Z-Finder Pro loupe with 2.5x magnification and diopter
 Three (3) Extender Frames
 Gorilla Baseplate and 3.2” Mounting Frame for Small DSLR Bodies (Canon 5D M3 Nikon D800/600 type cameras)
 Lanyard and Lanyard Hook
 Lens Cap, Sun Mask, and protective boot
 Z-Finder Dust Cover
 One installed and one additional Anti-Fog disc.  This also acts as a lens protector and is expendable.  More can be purchased here. We also have anti-fog wipes.

First, try it with Canon utilities.  I'd also do a camera reset to clear any settings which might be corrupted.
 
I always use a card reader to download, that USB connector on the camera is not reliable and breaking it can be expensive to repair.  I do use it to tether my camera to my pc when shooting products. 
 
If you have another computer or a laptop, try it as well.  That might eliminate any bad or damaged software issues.
 
Beyond that, get it repaired or use a card reader.
