EOS Bodies - For Stills / Re: 5DMkIII AF performance at f/8
« on: December 29, 2013, 07:09:43 PM »
I tried to AFMA the 1.4xTC III on my 100-400 with my 5DIII using FoCal, and the software gave up!  I consider anything under 600mm on the 5DIII as not long enough. As my 5DIII is going in for repair, I have used for the past few days the old 7D for bird photography. Its noise has virtually been eliminated at 640-1250 ISO using DxO PRIME. It's slow but miraculous. The noise just goes away with no perceptible loss of resolution of details of bird plumage.

from what I see there's no inexpensive way to get cracking shots at long focal lengths on a budget.



I think you will find that's pretty accurate.


Of course some people will not agree, but that's the interweb thingy for you.

Being as "inexpensive", "cracking", "long" and "budget" are not defined, the relevant sentence is as accurate as the old saying "how long is a piece of string". You can pick up a Sigma apo tele macro 400mm f/5.6, which has better MTFs than the Canon 400/5.6 for about £150, which probably falls into the category of inexpensive and some people would consider long.

I've actually been pleased with the results from my 100-400 plus MK II TC.  AF is plenty fast for most good light shots, and if the focus limiter is set, its even faster.
 
The IQ even with TC beats any similarly priced competition.  The new Tamron 150-600 is still a unknown, since we've only seen images from special hand made and tuned lenses.  Like many others, I'm watching it with interest.
This is a little woodpecker that flew up when I was testing my 5D MK III with 1.4   MKII TC last summer.  Its hand held, and more than adequate considering.  I did tough it up to bring out some of the deep shadows as much as I dared.  The aperture was wide open and its at 400mm, which is how it gets used most of the time.
 
 
 


Mt, you do get some really good results with your 100-400. What was the original pixel size of the crop of the woodpecker?

The 400mm f/5.6 is a very good lens, but is not razor sharp as others keep saying. The optics could easily be improved to sharpen it significantly, and IS nowadays should be there.
I have used a 70-200, 300 2.8 IS II, 400 5.6L, 500 IS II and a 600 F4 with crop and FF cameras. I would have to say the IQ and Sharpness of the 400 5.6L is very good for its price point. I am continually impressed with the quality and sharpness I get from the lens and honestly don't know how much better they can make it without a large price increase.

I will admit IS and a MFD of 1.5 would be welcomed but not at a large price increase. My main interest is sharpness and IQ and at the moment for $1200 this lens is a bargain.

Whilst this is not a strict comparison due to the different location and settings it still shows the performance of the 400 5.6L. One shot is with a 7D & 400 5.6L and the other a 1DX & 500 F4 IS II + 1.4x. Without looking at EXIF data can you easily tell which one was taken with $17,000 worth of gear to a kit worth $2000?



You can get great photos with most lenses if you are close enough to fill up the frame and rotten photos with the best lenses and gear if you are shooting under poor conditions and have to crop.  So, without seeing the full frame of each or being given 100% crops instead of just seeing reduced size images at unknown crops you can't make any meaningful judgements.

There are several lenses that would do the job better (for me) than the 400F5.6....
400F5.6 -   $1,525.46
500F4.0 - $10,509.00
400F2.8 - $11,638.96
600F4.0 - $12,983.56
200-400 - $13,220.96
800F5.6 - $14,114.43

This is what it would cost me today to get the various lenses where I live....and as you can see, there is quite the jump going above the 400F5.6 and that is why I would like to see an improved 400F5.6.

I think that a 600F5.6 is out as it would be similar in size and cost to a 300F2.8, which around here sells for $7,880.75 and I would guess that a 500F5.6 would be somewhere around the $4000 range.

Yes, there is a Tamron 150-600 about to come out, but I really doubt it will out-resolve the current 400F5.6.

For me, the 400F5.6 is as good of a resolving lens as I can afford.

Don
As usual you have the answers spot on. The 400mm f/5.6 is a very good lens, but is not razor sharp as others keep saying. The optics could easily be improved to sharpen it significantly, and IS nowadays should be there.  There needs to be lenses that the average person can afford so that superteles are not just the preserve of the lucky few who have the cash. Sigma or Tamron could make a really good prime but they have given them up for consumer tele-zooms.

B&H also has it for $1069.  And here is a detailed 2 page review.

Thanks for those links. I already knew that the lens is of very similar size and nearly as heavy as the 300mm f/2.8 II plus 2xTC so I had decided already not to buy. I downloaded all the photos and compared them with shots I have taken with the 300mm+2xTC on the 5DIII at similar distances and the 100-400mm on the Canon 7D. OK, the Tamron isn't as good the expensive prime but it compares pretty well with the 100-400. So, it look likes the Tamron is an excellent buy for those who want cheap access for a reasonably good 600mm. The reviewer did seem to have difficulty in getting his technique right for hand holding.

If the lens were smaller or could be retracted like the 100-400, I would buy one for travel. So, its continuing the long wait for the 100-400mm II.

The Canon f2.8ii + 2xTC is much heavier.

Canon 100-400mm   1.38kg
Tamron 150-600mm   1.95kg
Canon 300mm f2.8 ii + 2xTC   2.675kg

The Tamron when collapsed is the same length as the 400mm f5.6

Tamron when collapsed is 257.8 mm compared with 189 mm for the 100-400 mm.

I'm definitely hoping that it gets replaced with a 400mm f4 IS lens at an affordable price.

I realise that both the 400mm f2.8 and 500mm f4 are really expensive, but the 300mm f4 is under £1000, so shurely a 400mm f4 could be made that isn't that expensive.

A 400mm f/4 will be about the same size and weight as a 300mm f/2.8, unless it is a DO version, which is already available at an even higher price than the £5000 300mm f/2.8. So, I don't think a 400mm f/4 will be cheap.

If Canon is going to make something the size of 400mm f/4, my dream would be a super sharp f/5.6 500mm as a lightweight supertele  that could combined with 1.4xTC.

Lenses / Re: Acceptable AFMA difference for zoom between W and T ends?
« on: December 27, 2013, 02:56:06 AM »
I just sent an email to Roger Ciala and he replied back saying he would still "like to be within 3 AFMA values throughout the range of the zoom. "  I don't know if he's being a little tight on his requirements, but numerous lenses have passed through his company and that's the preference he seems to have reached.
If the change in AFMA is linear from wide to telephoto then the two point AFMA calibration should be adequate, irrespective of Roger Ciala's reactions.  Just do what neuro did and test your lens at intermediate zoom lengths.

...are there a significant number of OCD types going nuts looking for perfect lenses?

Five minutes on this forum should give you the answer to that question.

Part of the reason I read CR is for a chuckle, well done.  ;)

It is also very reassuring to discover that you are almost normal by comparison.

Not sure about widlife shooting but in my experience with the 1D4 shooting fast action outdoor sports, the 70-200 2.8L II + 2X TC outperformed the 100-400 in IQ and speed.  Additionally, zooming in/out with the 70-200 + 2X TC was much easier than a push/pull zoom that added unwanted movement to the camera even with a Gimbal head.

-1 - the great plus of the 100-400mm is as a walk-around lens for wild-life and safari or air shows and not as something to be plonked onto a tripod. When you are hand holding, movement of the camera is not a big deal.

A post Merry Christmas to all the CR mod's and forum participants. Wishing you all the very best of the new year!

The thread from yesterday, RIP teenage Canon Shooter Molhem Barakat killed in Syria age 17, appears locked. I wanted to add that the saying attributed to Burke in it - "All that is necessary for the triumph of evil is that good men do nothing."  - is apocryphal. It doesn't appear in nay of his writings. See: http://tartarus.org/martin/essays/burkequote.html

Just like the 100-400 dust issue.

Successful morning. Great walk with the family and just before reaching home on the way back a young heron decided to pose (7D, 100-400 at 300mm, f/5.6, 1/1000, iso 640, 100% crop, processed in DxO 9).
