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.

Try pg 325 of your manual.

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.

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.

A old 1D X? 
I'd ask Canon, not too many have worn out their shutters yet.  The camera should go much longer than 270K actuations.

I have not had a problem, but I did read one complaint about the finish wearing rapidly.

I just re-visited that pdf. I see no comparison of the various polarizing filters that I specified. Do you?
The coatings are the difference.  Read about the various coatings, or none.

I don't think it matters to FoCal what type of lens, as long as it has AF.

Use it with any AF lens. 
Here is my Tokina 17mm f/3.5 Prime

If you do want to do video, with the 5D MK III, plan on it eating up a lot of flash memory.  It sounds like you might run short.  You can throw the 32gb SD card into action rather than a backup, but having backups is good.

Best advice:
Be sure to have money to buy one after return it  ;)

Hahaha.  I'm afraid you are right.  There is no way I could afford a 5D mk. anything at this time, but someday!!!  :)

Is that 750 full-sized RAW files?

Thanks for the tips!  I think I'm going to use a bunch of 4, 8, and 16GB cards since I like to crack off a LOT of shots (so as not to miss the moment), and I don't like having all of my eggs in [a couple of baskets].  I think my wife and I shot over 2300 pictures at the last wedding we did. :)
2300 raw images at ~ 30MB/image = 69GB!  Thats a lot.
Don't forget, the 5D MK III takes 2 cards, so you can put in a 64GB CF and a 64GB SDXC to have a backup copy.  Or, just buy/rent a 64GB SDXC and use it for backups from your CF Cards.
 Never trust a new camera / lens combination test it out!! You should do a AFMA on the lenses/body.  Never trust a new camera / lens combination test it out!!
