Lenses / Re: Need opinions on telephoto choice
« on: October 11, 2012, 11:22:39 AM »
300mm is really not long enough for birds, don't buy one to use with a TC.  Look for a used 500mm IS MK I.
The 100-400mm IS MK II has been rumored for 7+ years, I would not count on any rumor.  The existing one is about the best value around.  I find that it autofocuses fine with a Kenko Pro 300 DGX on my 10D as well as my 5D Mark III.  I just bought the TC and will look at the quality in a couple of weeks after my hand heals from recent surgery.
The 400mm DO is another option to look at.  The newer ones seem to be pretty good.  Canon has refined the process for making DO lenses over the years.  The trick is to control CA's, and they are doing it well.

Hope the surgery went well!

Regarding the Kenko 1.4x, maybe I blew it.  I could have just gotten that to use with my 100-400 for a 560mm f/8 lens with AF.  Let's say the Kenko is as good optically as the 1.4xII - that can't be too bad compared to the 600mm f/4L IS II, can it?!?

Actually, on a serious note, Art Morris is really pleased about the Kenko 1.4x and the 800/5.6L IS.  He's got some very nice image to back that up.  But interestingly, when I look at TDP's ISO 12233 crops, the optical performance of the 800/5.6 + 1.4x (no real difference between MkII vs. MkIII there) and the 600/4 II + 2x (link), they look pretty similar (which makes sense - the 600 II is a better lens, and the 600 II + 1.4x is optically a tiny bit better than the 800/5.6).  So, for static subjects (where Live View AF would work fine), the 600 II plus Canon 2x would be worth a try...

Now I just need to decide if it's worth swapping the 2xII that I have for a 2xIII.  There is a chart comparison for the 2xII vs. 2xIII with the 70-200 II, and there's a marginal improvement - since I'll occasionally use that combo (when I don't want to bring both the 70-200 II and the 100-400), it may be worth upgrading just for that...

I took some pain killer, so it feels better now.  The surgery went fine, my left hand was done 3 weeks ago and is healing well.  I want to be healed before winter, I'm out in the country and have to run my tractor to plow my almost 1/4 mile driveway.  I need a good grip sometimes when it starts sliding.
I'll also want to try the TC on my 100L, more magnification is sometimes handy, I don't have the mp-e 65.  I did put it on my 24-105 where it worked fine, but there is little point to using it there.
I do have a number of older consumer grade lenses which are marginal without a TC, but I might try it with them just to see if they autofocus.
I'm also curious about combinations of TC's,  With my 1D MK III I've seen my 1.4X and 2X autofocus even at f/11.

If this unit will focus when it is on the the new 600mm f4L IS II, then it is probably worth the extra $$.

 ???

Certainly it will AF. So will the Canon 1.4xIII, since either 1.4x TC will make an f/4 lens into an f/5.6 lens, and all Canon bodies can AF with an f/5.6 lens.

Did you mean will the Kenko 2x allow AF with the resulting f/8 combo. A poster on a bird forum reported that it will, but also showed that unlike the Kenko 1.4x which has decent IQ, their 2x turns a sharp lens to mush.
+1.
Thanks Neuro.  hand surgery tody, so I can't type well much less test cameras.  It did work very well on my old 10D - suprising.  I do not have many f/5.6 lenses to test it with.

Lenses / Re: Calibrate Canon 24-70L?
« on: October 10, 2012, 10:48:27 AM »
Sit the camera on a tripod and aim it at a brick wall 15 feet more or less away.  Make sure it is perpendicular to the wall.
 
Use live autofocus (not quick AF).  This will focus the lens according to the highest contrast at the selected AF point. 
 
If its sharp, it needs AFcalibration.  If its sharplly focused in the center but not at the edges, thats normal since the lens has a large field of curvature.
If the lens is still not sharp when focused this way, it has more serious issues that Canon might be able to resolve.  I've had five of them, on a crop camera, they were not excellent, but they were adequate..

Lenses / Re: A final goodbye to my 50mm f1.4 lens
« on: October 09, 2012, 09:27:59 PM »
The only reason I'm even thinking about holding onto the 50 1.8 is it's a lot easier focusing for video than the 35 2.0.
Do you have the 50mm f/1.8 MK I?  The MK II is the poorest lens to manually focus I've owned, and by a large margin.  The MK I is fine. 
 
The 35mm f2 also has a actual focus ring.

You did not ask about lighting.  Do you have lights?  A single flash will not light a area wider than 24mm, so you will need multiple lights for creative settings.

I have poor hearing, and tend to not hear something dropping out of my pocket, (or even someone shouting to tell me it dropped out).  I'm glad you got it back.

My canon 7d appeared with an error 30 and now 90% of the pictures appear too dark. Is there any solution?

Thanks
Stop using it and send it for repair.  A bad shutter can come apart and cause more damage and double the repair bill.

A little bummed about the 24-105 not working well with the crop but I'm glad I asked before purchasing :)
The 24-105mm L works very well with a crop, its just not a "all in one" walk around focal length.  The images on a crop body are fantastic. 
I use my 15-85 on my 7D rather than my 24-105 L because of the focal length issue.  Its nice to have just one lens when out walking around.

Third Party Manufacturers / Re: Considering switching to Nikon
« on: October 09, 2012, 01:08:38 PM »
I tried a Nikon, and invested about 10 K in a D800 and top lenses.  The D800 is great at low ISO, but you have to be extremely careful with it.  I think its a great landscape body.  Lenses that match the body really don't exist, as I painfully found out, and there is nothing close to the quality of the 24-105mmL, the 135mmL, or the 100-400mmL that are some of my most used lenses.
I sold it all, and bought a new Canon body along with a  new16-35mm L  The only images I really liked from the D800 were the low ISO images, 400 or lower.  The DR of the D800 at ISO 100 was amazing, so for bright light landscape use, it is fantastic.
