It interpolates the value.

EOS Bodies / Re: COSTCO Deal
« on: October 06, 2012, 09:45:49 PM »
just saw a deal in Costco, thought it was a good one so figured I'd share: Canon 7D + 28-135mm USM lens + 320 EX Flash + 8GB CF card: $1799.

Just thought this is a good deal for this in the market for the awesome 7d.
The Camera and lens sells for $1538 at B&H, Adorama, and Amazon, the flash for $224, and a 8gb card maybe $15.
 Total $1777, and you don't have to pay sales tax if you are out of NY state.

I got my 64 GB 1000X Lexar card yesterday, but haven't done a similar test.  B&H did not have a 2for sale last week when I ordered mine, but 64GB covers a session very well for me and matches the size of my SD card.

Lenses / Re: Lens Tweaking Service
« on: October 06, 2012, 09:25:59 PM »
Roger over at LensRentals has to be hit with this ask every day...  Of all folks, he has the tools on hand, and I believe folks would pay a premium if they could purchase new lenses that have been checked out.
Roger has tools to check a lens, but only has the know how to tweak a few adjustments in a lens, and some he leaves to Canon.
I do not think it would be feasible to sell new lenses, since people would only pay a premium for the top 10% and you would be left with the other 90%.
A testing and report issueing service would put the onus on Canon to fix a bad lens, and would not void a warranty.

I just realized that DNG.files are like 3x faster in develop mode to load than canon's own cr2.. Anyone else here who noticed that?
I don't use LR4 yet (I am getting a system that will run it shortly) but I do use DNG because the 5D3 is not supported in LR3. That said, when using DNG it helps to use the conversion setting of 'Embed Fast Load Data'.

On paper DNG is supposed to be as good as RAW, but does it have "all" the information that a RAW has? Has anyone done tests on this?
Yes and No.  It depends on which of the three versions of DNG you select.  If you pick the one with the RAW files embeded, everything is there.  Otherwise, some of the Canon unique tags may not be there.  Lightroom doesn't use these anyway, so it makes no difference.
You can also open DPP and batch save the files to photoshop or wherever you want them.  They will be converted to tiff files,which are more universally used than DNG.  You will still lose the Canon specific tags.

Why don't you send it to Tamron rather than a online retailer for service?  It sounds like you have a issue.

Lenses / Kenko TC and AF at F8
« on: October 05, 2012, 09:46:46 PM »
After reading that the 1.4X Kenko PRO 300 DGX was autofocusing at f/8 with Canon super teles on 1D X Bodies, as well as reading the experiences of some who posted here with the 5D Mark III, I decided to go for it.
My TC arrived late this afternoon, and I decided to give it a try on my 100-400mmL.  At 100mm, its a equivalent of f/6.3, and the 5D MK III indicates f/6.3.
I tried it indoors in fair-good light, and it autofocused smoothly and quickly.  Then I zoomed out to 400mm which is f/8 equivalent, and I was pleased when it snapped into focus repeatedly.
Then, I decided to give it a tough test, and took it outdoors where it was rapidly becoming dark.  This is the area where TC's usually fall flat.  I zoomed out to 400mm on a far distant house with the sky still a little bid bright, and it did a fair job of autofocusing.  slower, but suprisingly fast for the situation.  The ISO level was 8000, but the image under exposed.
Then, I tried it without the sky in the background on my rose bush in deep shadows, but it would just hunt.  This was a very dark area.  Finally, I tried it on my bird feeder at ISO 12800, which was a correct exposure, and it smapped to focus quickly.  I was amazed.
Its too late to do any more testing tonight, but I'll try testing other lenses and combinations as I can make time.
Already, I can say its worth the price over a Canon 1.4X MK II TC as long as you do not need weather sealing.

You can try the in-camera raw processing to be able to have more control over image quality.  If you want the best, avoid jpeg.  Its fine for ebay and craigslist photos, but for archival work, they won't stand the test of time.
Raw images I took several years ago and processed with Lightroom 2 can be reprocessed with the latest version, and do look much better.  You can't do that to in camera jpegs, they are frozen in time, and best used for cases where time is more important than quality.

mmmm..... I'm not a pro nor make money out of photography in any way but I'll be sure to read the small print now, thanks for the warning!
Great photos can be blurry or sharp, and the news worthy ones are often taken by amateurs who happen to be in the right place at the right time.  Their impulse is to share a photo by posting it immediately, not realizing its worth a lot of money.  If you post it on Flickr, as long as you have your copyright attributes set, you are covered.  Canon though wants you to turn over the rights to them.

they sit on things until a market can support mass production.
Exactly right.  No different than a prototype of a new car.  Handmade test products will mostly never be in production, but you learn from pushing the limits even if its only a custom 1 off item.
Making a 120mp sensor is easy when compared to making a camera that can use them, or processing the images in a home computer.

About 90% of the equation is the photographer.
If you are happy with your camera, then its right for you.  However, that does not apply to others, each has their own list of wishes..
A perfect camera body will never happen, so make the best use of what you have.  You can work around most features, but for some uses like low light with no flash and rapidly moving subjects, once you get the fastest glass, there is no good work around.  Then do you really need to consider the options.  That might only apply to a small overall percentage of photographers.
 However, those who have the additional capabilities sometimes discover that they have been missing something and never knew it.

Canon General / Re: Shutter Assembly Replacement
« on: October 04, 2012, 09:31:09 PM »
Sorry, I misread what you were asking.
Its difficult to give a cost for a shutter.  If it dies at a ripe old age, its likely that the mirror box and some other wirk will need to be done, while a new camera with a bad shutter might get fixed for $500.  with your discount, $300 allowance for the shutter sounds reasonable.  I sold my 1D MK IV for $4200 recently with a very low shutter count, under 2,000.

Lenses / Re: Canon 16-35mm II + Reikan FocCal Pro --- Tips
« on: October 04, 2012, 08:40:27 PM »


I just ran my 5d III with 24-70 II through FoCal. This is the test results FoCal gave me on my 24-70 II @ 24mm. (-5 seem to be the best)

Looks good.  Its a nice bell curve.  I must run the program with different options, I always have many tests near the predicted point.  That usually changes the results by a point or two as it gets more precise from more shots.
