Lenses / Re: Tamron 150-600 mm with 5dIII: Menu setting critical

How do you find this lens for sharpness at the 600mm end?

I am thinking of getting one for shooting airshows but I've seen it heavily criticised for bad softness near the long end of the zoom.

How is yours for sharpness near the 600mm end?

I will be using it on a 5D3 body.

really?

you did not notice the threads we have here about this lens... with example pictures?

No I didn't, no.
i was looking for owners opinions.

I had my eye on the Tamron but Tony Northrup reviewed it and the 500-600mm shots he posted were very poor - https://www.youtube.com/watch?v=1fmMG5jgDwk

Have a look at this post: http://www.canonrumors.com/forum/index.php?topic=20668.msg391571#msg391571

Mr Northrup may not be the photographer he claims to be  :)

Impressive!

Excellent points Neuro, Makes perfect sense to me.
Having shot with the 70-200 f2.8L II? 2 x TC III combination at a few airshows last year I was pleased with the quality, but having to frequently crop at 100% I was always going to get image degradation.

I had my eye on the Tamron but Tony Northrup reviewed it and the 500-600mm shots he posted were very poor - https://www.youtube.com/watch?v=1fmMG5jgDwk

Also, due to the lack of worldwide stock I am  struggling to get hold of one of them, even to try, but it may be better to wait and see what I think when I actually get hold of one.

An actual airshow will be the ultimate test though!   :)


If sharpness is king for you, putting a TC behind anything other than a 'great white' will result in a pretty significant IQ hit.  For example, comparing the 400/5.6L to the Tamron 150-600, they are similar in sharpness at 400mm, and the Tamron is slightly sharper at 500mm and only slightly softer at 600mm than the 400/5.6 + 1.4x.   For the 300/4L IS, the Tamron is sharper at 400mm than the 300/4 + 1.4x, and also sharper at 600mm than the 300/4 + 2x.  The Tamron is also sharper at 400mm than the 70-200 II + 2xIII that you have been using (that comparison is shown here, you can use the drop-down menus to compare various options).

In all those cases, the AF can be an issue.  However, Bryan (TDP) indicates that the AI Servo performance of the Tamron is pretty good.  Putting a TC on a Canon lens slows down the AF - by 50% with a 1.4x TC and by 75% with a 2x TC.   Plus, the Tamron would allow you to use all your f/5.6 cross-type points whereas with the 560/600mm f/8 Canon combos, you're limited to the center point with 4 surrounding expansion points.

Prior to the release of the Tamron 150-600mm, I'd have said the 100-400L was arguably the best lens for an air show.  The flexibility of the zoom is quite useful, and the IQ is very good.  Honestly, given the above, in your place I'd have another look at the Tamron - it's as good or better up to 500mm than the other options you're considering, and at 600mm it's actually quite simliar in sharpness to the 70-200 II + 2xIII. 

The unfortunate reality is that if you want longer than 400mm with excellent sharpness and fast AF, you really need to be looking at the big supertele lenses.  If that means selling body parts and you're unwilling to part with a kidney or a lung, you'll have to compromise - and the Tamron is actually a pretty good compromise, IMO.

Lenses / Lens choice for airshows
« on: April 30, 2014, 08:11:51 AM »
I have a Canon 5D MARK III body and have been shooting air shows using my 70-200 f2.8L IS II with a Canon 2 x III extender.

This works pretty well but I could be doing with some extra reach so I am looking at a new lens or lens/EX combination without selling body parts to finance it.

I have come down to the following options:

Canon 400mm f5.6 L with a 1.4 TC - this will get me just under 600mm but at f8. 
This worries me in low light situations and I am unsure how the 5D3's AF will suffer - it might not be good for airshows.

Canon EF 300mm f4 L IS USM with either a 1.4 or 2 x TC - this gives me IS and with the 1.4 TC a 420mm lens with f/5.6 and IS. I could also use the lens with a 2X converter to get a 600mm lens with f/8 and IS.
Once again though I am concerned about image quality and AF performance, particularly as I will be focusing fast jets.

Does anyone have a similar combination and can help with the performance of this body/lens and the image quality I can expect?

Sharpness is king for me, I was looking at the new Tamron SP 150-600mm f/5-6.3 Di VC USD but I have ruled it out due to the poor image quality above 500mm.

Your shot here looks soft.
Like you I will be shooting fast moving subjects (jets) and I am concerned about how sharp this lens can be.
The alternative is a Canon 400mm f5.6 L with a 1.4 TC which is reportedly sharper especially as I will be shooting at the long end most of the time.

Have a look at the Tamron review here - the 600mmm shots are very poor:

How do you find this lens for sharpness at the 600mm end?

I am thinking of getting one for shooting airshows but I've seen it heavily criticised for bad softness near the long end of the zoom.

How is yours for sharpness near the 600mm end?

I will be using it on a 5D3 body.
it is plenty sharp at 600 but it IS sharper at 500mm

If you dont want to use dot tune can you still input Focal calibrated AFMA values into a ML enabled 5D3?

Software & Accessories / Re: Magic Lantern for 5d3 1.2.3 released
« on: March 17, 2014, 11:18:51 AM »
I shoot still virtually all the time - is Magic Lantern still useful for me?

44
Is this the new nightly build for the 5D3 that adds this?

 Latest Build

    Built on: 2014-01-24 00:11:15 +0000
    Changeset: 42c206c28f3a8b33e04ac075f66526dcf55901bc

I am really interested to try this on my 5D3 as I have seen some wonderful shots taken using features such as dual ISO but just concerned, as we all are, of damage to the camera.

I work with a single 5D3 and have heard about boot times being much longer.
Also, how does any settings I have like AFMA and Canon stock settings work along with ML - are they still used?

Sorry for the questions, ML newbie here!  :)

This is a better picture of the locator I am looking for:



Does anyone have one I can borrow, please?
