Portrait / Re: 50mm f1.4 group photo
« on: August 15, 2012, 12:42:07 AM »
just edited my first post included the photo. thanks
After downloading and viewing the image and exif, I wondered if you were using a tripod?  1/20 sec for a 50mm lens with a 22 mp body is pretty slow.  I'd prefer to use 1/125 sec and set the aperture to f/2.  It looks like some motion blur, but it might just be that the use of ISO 12800, and taking it as a small jpeg which throws away even more detail.
I'd recommend using raw and post processing to control the NR and sharpening.  The 5D MK III does not do a spectacular job with jpegs, particularly if you have the images set to small jpeg.

I had a Wimberly for my 600mm f/4 and it was wonderful.  However, it would be overkill for the much lighter 500mm lens.  I'd go with Neuro's recommendation, or use it handheld or with a monopod.

Lenses / Re: Canon EF 35 f/1.4L II [CR2]

Considering today's 35 f/1.4 is already superlative...what, aside from the price tag, will be different with the new one?

b&

The 35mm 1.4 was spectacular when it was released, now it's just average. It's so average in fact that a third party 35mm 1.4 Canon EF lens you can buy for $350 brand new is much better than Canon's own $1350 35mm 1.4, which is ridiculous:

http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=771&Camera=453&Sample=0&FLI=0&API=1&LensComp=121&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=2

Just from that comparison I see the following that could be noticably improved:

-Corner sharpness
-Mid frame sharpness
-Severe Color Fringing

Here are some other factors which could be improved:

- Flare resistance (better coatings)
- mid frame and corner sharpness for meridonial detail stopped down
- Color fringing stopped down, it's plainly visible even at f/8.0
- Purple Fringing (I notice this in my copy)

Don't get me wrong even with all these problems the 35mm 1.4L is probably my favorite prime of all time ever, the combination of pleasing quality, focal length and aperture are amazing.

However if it were as good as say this, well... we can only dream.

I bought one of those SammyYang coke bottles you refer to, but the autofocus would not work on any of my cameras.

Is anyone else experiencing problems with the Canon 1DX body not autofocusing with some of their lenses?

I have a 1DX that will not autofocus at all with my 24-105 IS L lens; as soon as the camera is turned on you get constant lens motor noise and the AF indicator in the viewfinder flashes continuously.  The lens motor makes a zip-zip-zip-zip noise (always in groups of four).

I went into my dealer and he tried my lens in another 1DX body; the same problem happened.  However, we also tried it in my 5D and one of their 1Ds mk III bodies and the lens worked perfectly.  This suggests to me that perhaps the lens is not faulty but that there is perhaps some incompatibility problem with earlier 24-105mm lenses?  I'm also having intermittent problems with the 1DX failing to autofocus my 500mm f4 IS L lens (a mark 1) but could not reproduce the problem with their 500mm (mark 2) lens in the shop.  My experience is that sometimes the 1DX cannot focus my 500mm lens until I manually focus it close to 'in focus' when the optics suddenly jump into life!

It's shaking my confidence in the 1DX's ability to work with the full range of EF lenses and so far Canon UK don't want to know - no reply still to my e-mail to my CPS rep and the repair centres point me back at the dealer.

If you are thinking of buying a 1DX, I suggest you be careful and test it with all your lenses first!
It sounds like a lens issue, there can be issues with lenses.  Trying a different lens might help point you in the right direction.

Along with the poor global economy, Adobe's big drop in prices is causing the industry to drop their prices accordingly.  Thats good for all photographers, prices have been too high.

Lenses / Re: 85mm f/1.2 ii or 135mm f/2
« on: August 14, 2012, 03:31:15 PM »
I have a 135mm L, its great for FF, but I'dlove to have a 85mm f/1.2.  I do have the f/1.8 version, but it have used it less than half as much as my 135mm L, in fact, it gets basically the same use as my 50/1.4 and 2/3 the images of my 35mm L.
I keep looking for a deal on one, but they are not as often found  locally on Craigslist.

Software & Accessories / Re: Stitching panoramas question
« on: August 14, 2012, 01:46:01 PM »
It really does depend on the technique and the range you need to cover.  I'd do a quick and dirty one to get a feel for it.
I played with the Canon software just taking images by rotating the camera on my tripod.  Thats reasonably ok for distant scenes, but a problem for closer ones.  Still, they came out very well for my not having done it before.
Here is a link to the photos and the panorama.

You linked to scaled versions of the images but i found the originals in your gallery  :)

It's pretty hard come to a definite conclusion regarding the quality. Also at the shot with the 2x converter a cloud is on the main tower reducing contrast and it seems like some kind of noise reduction is employed. Additionally there may be air turbulences and slight focusing errors etc.

I think most people will be happy with the 1.4x extender on any tele lens F/4 or faster but the 2x extender is only a compromise.

A 50mm shot for comparison. Try scaling it :)
 

That's quite impressive!
Yes, there are flaws in the test, a distant object miles away is not really the best type of test, that pesky air, clouds, water vapor, etc change all the time.  Also, from a wooden deck, someone walking in the house might affect it.

Its pretty clear that a 1.4X does a good job with a 10mp 1D MK III.  The result with a 18mp 7D might be different, I might setup on concrete one day and try that.  I now have a laptop holder on my tripod, or can use a long USB cable and focus / capture remotely to get the best possible image.  However, something closer might be better.

I really do not use my 100-400mm L with TC's, its too much of a bother for any possible gain.  I can crop most of the time, and other issues usually out prioritize using a TC.

Here is a cropped image of a female redwing blackbird as she dropped from our crabapple tree to the ground to pickup sunflower seeds. I loved the way I could AF on the bird right thru the clutter of the tree with my 5D MK II.  I always was wondering at those who could not AF with it. 100-400mm with no TC.

Software & Accessories / Re: Other photography websites...
« on: August 14, 2012, 12:44:14 PM »
It's the sign of the time... people realized that the market after Flickr is still the same, odds of making money same, same people in the game, and hoopla on sites as Flickr don't really mean anything but hoopla, and in order to make some money you have to go and shoot weddings or pets or children in the neighborhood, not exactly glamorous photography work, so they are loosing interest.
I think this is the reason why Canon is in trouble, lack of understanding that 80% of 5D II buyers were amateurs living mirage of "FAME" on internet sites like Flickr, shelling thousands of dollars for semi pro cameras and lenses.
Well the dust is finally settling down after the digital explosion, now we will see whats next.
How does your rant relate to the questions by the OP? 
What does the OP's question have to do with making money?
Why do you think Canon is in trouble.?  Any evidence? ... like losing market share?
Flickr is a image sharing site, it does not claim to be making money for photographers.  It has certainnly, however, changed the way people display and share images, and provided a channel for communication between photographers.
I no longer use it, but my wife and relatives do.  It suits the needs of many millions of photographers, but not everyone.
Pro photographers who wish to communicate their work with millions of other photographers also post images, even if its not a primary channel for them.

The lens is fairly new, I love it.  These are difficult shots due to the distance.
Reported Settings.  These are what is recorded in EXIF and, in the case of stacked TC's the f stop is wrong.  I used AV setting of f/11, but the aperture of the lens would have varied according to the TC with it being stopped down more without a TC
Also, it was a winter day and the light varied from shot to shot so the shutter speeds varied according to available light.
No TC  - 1/2500 sec f/11, ISO 800
1.4X - 1/3200 sec f/11 ISO 800
2X   - 1/3200 sec f/11 ISO 800
1.4 + 2X - 1/2000 sec f/11 ISO 800 (not the actual equivalent aperture)
It might be interesting to redo them with my 1D MK IV, but in our near 100 degree weather, the air is too turbulent, and the 1D MK IV is going to be sold soon.

Another thing is: Did you scale the images made with the TC or change the focal length? Comparing the length of the tower by hand doesn't give a magnification of 2x or 2.8x compared to the 1.4x (maybe this is also done on the webpage). I ask this because scaling images is also often problematic and there is quite some discussion on how you should scale the images in order to provide a "fair" comparison.

What we can conclude however is that taking images with a TC is much more complicated than using the bare lens.
They are crops, so  the scaling cannot be measured when you crop a image.  As noted, I cropped them to show the tower at about the same height, except that the no TC crop resulted in a 100% crop so it is a little smaller.  If the objective is to see which combination produces the most detail of a distant object, a crop works best.
Full images are linked below to avoid taking up bandwidth for users.

Portrait / Re: 50mm f1.4 group photo
« on: August 14, 2012, 12:10:27 PM »
Hi all, new here and new to photography

Just need to ask a simple question.......
I recently took a group photo (around 8 people) using 5D3 with a 50mm 1.4 but it came out blur except where I was focused.

AV, AWB, f9, ISO auto, one shot, using only the centre AF point.
basically, my wife and her two friends next to her were pretty sharp but the people on the ends were blurry.

I tried with all the AF points on but it just auto focused on the couple of people closer to the camera.

any suggestion would be grateful. Thanks
Can you post the photo or a link with exif info?  There are several possibilities.
How close were you?
The camera may override your AV settings if necessary to get a properly exposed image, check the exif and see what it says about the settings.  If that happened, you might have f/1.4 rather than f/9 as you thought.

Third Party Manufacturers / Re: Does Zeiss glass ever go on sale?
« on: August 14, 2012, 11:41:37 AM »
Maybe when pigs fly but I've never seen Zeiss on sale.  However, you can buy used and I've had good luck with four Zeiss lenses that are like new.  Zeiss, as you probably know, is built like a tank so they retain their value and condition if cared for properly.
If you know what you want, you can seek out sellers from Craigslist or Ebay. I've rented the lenses I thought I might want first from LensRentals or 'that other guy' which helped in my purchasing decisions. 
If you choose to buy new, check Amazon and B&H. I would stay away from Adorama....never a good experience there, horrible.....
I've bought from Adorama many times over the last 30 years, never a problem.  They almost always get the new models out to buyers first. Amazon is really slow to get new DSLR models in stock, and has cancelled my order for one after I was waiting for two months.  I buy a lot from Amazon, but I never pre-order a new DSLR model, its a formula for disappointment.
B&H recently got in trouble with Canon for some unknown reason, and had their initial deliveries of recent models delayed, and their allotments cut.  Supposedly, thats been patched up.

If you really miss your autofocus, there is a company that converts your manual Zeiss to AF, but its a bit pricey.
Can you tell us who does that?  Conrus converts Contax N lenses (which were made by Zeiss) into EF compatible AF lenses, but the Contax N lenses were already autofocus, not manual.

Best of luck. Let us know what you find out there.

EOS Bodies / Re: 7d - max ISO issues
« on: August 14, 2012, 11:24:45 AM »
Canon recommends a camera reset after installing new firmware.  There are many combinations of options that can make weird things happen with a major firmware upgrade.
I'd do a camera reset and then restore the settings one at a time if you want to avoid weird happenings.  If you did that already, and its happening, then let us know.

EOS Bodies - For Stills / Re: EOS 7D FW2.0: Problems anyone?
« on: August 14, 2012, 11:20:13 AM »
Canon tells you to reset the camera after upgrading firmware.  It can end up with a combination of settings that no longer exist in the new firmware and cause some weird thinngs to happen.  I've had no issues with mine after the update, other than restoring all the settings after resetting it.

I'm sorry to report these are the slowest loading pictures I've seen in years. I get a few lines of pixels (literally) if I wait for 10-20 minutes. Could you give us a taste by uploading some images to a fast server, like cr's or flickr or something? 's 'cause I'm lotsa curious ;)

Hmm...  interesting.  It's loading slow for me as well.  Earlier today it was really fast, so I wonder if something is going on with my hosting server.  Sorry about its slowness right now...  my hope is that it's temporary.
Yes, it took forever to load them, sometimes its better to just post a link rather than making us all wait five minutes for them to download.
Thats why CR asks that a maximum of 4 images be hotlinked.
