Lenses / Re: Just bought a new Canon EF 70-300L IS USM lens.
« on: January 13, 2013, 07:04:45 PM »
I did a quick and dirty experiement today to check the exposure compensation.

#1 photo: 5D3, Kenko 1.4X TC, 70-300L, 0 EV, blown highlight is evidence, couldn't be recovered in LR4

#2 photo: same as above with -1 EV compensation, much better, some highlight on the bird is still blown.


These are quick and dirty experiements, so appologize to those of you who are purists :)

and just for kick, I swapped out the Kenko for the Canon 1.4X III.  AF is a bit sluggist and the lens makes a grinding noise.  I put the combo on my 1DX and the same noise persists.  My hummingbirs were not cooperating, so I went out and shot an Amerian Kestrel instead.  The IQ is fantastic, but I guess we know that already.  So, if Canon can fix the AF issue with firmware, this is in fact a viable option.

Lnguyen1203, are you saying that whenever you mount your Kenko 1.4x to your 70-300L you set the 5D3's exposure compensation to +1?

-1.  You need to substrate light, which is a bit weird.

Appreciate your confirmation, Lnguyen1203. I could never tell for sure, from what others all over the internet have said about this combo, until your definitive statement. I'll be ordering up one Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter. Thanks!

You're welcome.  Just remember to substrate about 1 stop of light.  I don't quite understand how the Canon light meter works, but that is my experience.  The 5D3 knows the presence of the Kenko and will give you the correct focal length and aperture setting, but the light metering is off by about 1 stop.

Canon 1.4x TC won't fit with the 70-300L, so it is not a choice for this combo.  Folks will want to compare with the 100-400L, but the reason I got the 70-300L is it is a better, lighter, smaller lens than the 100-400 for a walk around and medium telephoto lens.  I don't use the 1.4x much on it, but have done some test shots with hummingbirds and they look fine (even in not so ideal lighting).

I put a Kenko 1.4x teleplys Pro on the 70-300L and the 5D3 works pretty well AF at F8.  No need for new firmware ;) for this combo.

Lenses / Re: Canon EF 500mm f/4L IS II travel bag for Alaska
« on: January 08, 2013, 10:17:16 AM »
I have the Lowepro Flipside 500 and have taken it on many planes including the regional jets.  It will fit under the seat of the regional jet.  The overhead compartment of these jets is very tight.  If your destination is Anchorage, no problem.  But if you need to take something like a flat plane to Katmai, you have to hand over your bag, but the Lowepro is well padded and I have no issue.  I also put the gear into my regular roll on bag, wrapped with clothes on a recent trip when I didn't want people to know I was carrying camera gear.  The roller bag is nice and easy to wheel around the airport.

"Reportedly, it will fit in a Lowepro Flipside 500 AW (which I don't have, yet), which is ok for carryon."

my 500f4 II when mounted on a 1DX fits very tight in a Lowepro Flipside 500 AW.  I can't see how the 600f% would fit even when not mounted.  You may need a bigger size bag!

agreed with the price too good to be true.  I paid ~ $3700 for a "like new" 300F2.8 Mrk I IS 1 year ago.  The lens is incredibly sharp at 300mm and takes the 1.4X TC well.  $1200 would be a steal unless something is really wrong with it.

How did this thread go from 500 vs. 600 to cropped sensor vs. FF?  He already have a 1DX and is not asking about 7D vs. 1DX plus 1.4X.

Lenses / Re: Worth it to upgrade Extender 1.4 II to a Mk III?
« on: December 31, 2012, 03:18:36 PM »
I have upgraded from the 2X ii to 2X iii and am pleased with the upgrade.  The 2X iii gives me better sharpness, more details in the shadow when used with the 500mm f4 II (see an image here at 1000mm focal length and f11).  I have also used the 1.4X ii and will upgrade to the 1.4X iii (already placed order) to get better AF with the 500mm f4 ii.  According to Canon the teleconverter 1.4X and 2X Mark III have a chip inside that allows faster AF with the new super telephotos like the 500mm f4 II.  So, I will post some pictures when I have the 1.4X iii, but my expectation for IQ improvement is small if any and I will most likely can't tell the difference.

Like you, I'm not a pro.  I shoot for fun and an excuse to be outdoor watching the wildlife.  I considered both the 500mm and 600mm like you and decided to go for the 500mm because

1. It's far easier to travel.  I carry a Lower pro 500 bag on all kinds of planes, even the regional planes that service Yellowstone Bozeman airport (may be a 20 seater).  No airlines has given me grief about carrying it on board.

2. Handholding - I do have a tripod with gimbal head, but it is just nice to have the option of handholding.

3. Hiking - I carry a 1DX with the 500 mm and 1.4x for 2 hours at a time without much trouble.

4. I use both the 1.4x and the 2x and are happy with both.  I suppose the same will apply to the 600 mm as well.

I suppose, the cost of a 1DX and 500mm is less half the cost of a new luxury car.  I'm still driving a 2004 Saab convertible which I bought in 2007 as a certified preened car.  Do I feel guilty for spending that much on a hobby? Absolutely not!

Software & Accessories / Re: Tripod: Carry-On or Check-In
« on: December 12, 2012, 09:43:09 AM »
I often carry my Gitzo 3530LS tripod (without head) on board attached to a Lower Pro 500A plus a computer bag on domestic flights and never had any issues.   I also check the tripod with a bigger suitcase at times and also have no issue.  The main worry of checking the trod is lst luggage.  I would wrap it with the clothes so it is well protected.  Have not done it with international flights, but I have seem people carrying it in Tokyo airport and the guy told me he travels everywhere with his tripod and no issue.

Canon General / Re: Recommended photography books

If you are into birds or wildlife, Authur  Morris " Art of Bird Photography II" is a good book.  It's available on CD only, but I loaded it on the iPad and its great.

Lenses / Re: 70-300L for Outdoors?
« on: December 06, 2012, 11:31:12 PM »
The 70-300L is a great, light weight, compact lens.  Great for travel.  If weight and ost are not of a concern, the 70-200 is a great lens.  But if you need the reach, I'd go for the 70-300L instead of 70-200 plus converter.  If you need more reach, the Kenko 1.4x teleplus pro will work with the 79-300L and AF works under good light without taping the pins on my t3i.  It is a good choice.
