Time has passed this lens by - it is two years to late.

The 150-600 zoom is the new kid on the block and the imminent Sigma S version could be a very good lens.

But then.......nothing to beat Canon quality control is there?

But really the 100-400 should have been brought out the same time as the Nikon 80-400 which by some accounts isn't all that brilliant.

Nice to see more and more photos taken from this lens.

I'm sure that the Sigma OS will be even better.

Better still I think Can/Nik will be looking at this zoom sector and perhaps thinking we are loosing out here because we dictate rather than listen to customer wants/desires.

The dp iso 12233 crops suggest you have to stop down by 1 stop to get decent results - so then it's 600/8 up against the 600 prime at f/4!

Here's my safe bet. You may treat it as a [CR3]. ;)
There will be a brand new logo on the top right corner on the front of it.

...and still using same size 20.2 sensor

Sweet Jeebus, look at that MTF!

..there are MTFs and MTFs. Look at the ones for the 400/5.6 - they don't do this pretty good prime much justice.

Nevertheless the MTF curves at 560 for the DO are impressive. But expect some competition from the Sigma 150-600 Sport at a lower price but a bit heavier.

Well, if I need to reach 560mm, I'll be using my 600/4L IS II, giving me an extra stop of light, and even more reach with a TC if needed.   :D

Sure 'cause the 600's not, like, double the weight and size or anything

Yep, I bet that 600/4 II is a brute to carry around - all up weight with box must be quite something

The image quality would have to be impeccable though...

Something the two DO lenses released to date aren't known for. 

Personally, I'm not really interested in a 400mm f/4 lens...I'd rather have the 300/2.8 for the faster aperture when needed.

You reach 560 with this lens with just 1.4XTC whereas the 300/2.8 is still only at 420. To most people a 2xTC degrades the image to much. So basically this new lens could beat the 300/2.8 in the range 400 - 560. That's pretty important - we shall see.

I think Canon are sticking with DO development as it may be the only way to significantly reduce the weights of the big whites at some point in the future.

Well, here it is:
I believe this will be a better option than the Tamron optically, maybe I'll buy one for myself  ::)


For twice the money it better is noticeably better.

Though constant f5.6 would have been nice.  ;)

...still a lot cheaper than the Sigma 300/2.8 + 2xTC so maybe assembled outside of Japan ie only slightly better optically if you get a good one than the Tamron equiv. Nice strong mount though.

How much is Canon paying you to suffer and defend the brand?  If the threads bug you, don't read them.  Better yet, go out and take some shots.  As far as I can tell, the D810 is a Nikon-version of the 5D3, but with a substantially better sensor.  It's natural that people want more oomph out of their cameras and its natural for them to look at competing brands for validation of their choices.  Seriously, go out and take shots.

How about you don't wade in, missing the point by a country mile with worn-out, rote, flamebait clich├ęs?

The folk here who "defend" (which, incidentally, is an immature, immotive characterisation of what's really going on here) Canon, do so:

Because they don't appreciate lies, half-truths and irrelevances presented as "facts" - much less as show-stopping, catastrophic failures by Canon.

Because they know, from their own use of Canon equipment, that it can achieve anything they need a camera to do - which is, images (not pixels) of the most sublime image quality anyone might possibly wish for.

Because the whining about Canon's "sub-standard" sensors says more about the whiners (and their own failings) than it does about the sensors.

Simply put, they "defend" because that's the proper reaction to the bullsh*t. Other people who (God help them) might choose to visit Canonrumors to get some useful information about the capabilities of Canon cameras deserve a balanced view that pushes back against the interminable DR crap.

And it'll continue to happen for as long as the DR whiners continue to push their DR agenda, and as long as that agenda continues to mean sweet FA for the vast majoiity of photographers out there in the Real World.


"...sweet FA..."

Your words.....just about describe your rather aggressive over the top rant apparently in "defence" of Canon!
I bet Canon have never heard of you.
Just try and be a bit more open minded and less fanatical in your next post.

It's been 13 years, do you have any evidence to say DO isn't ready for prime time?  It'll take a lens release to show it...

Canon have stuck with DO because they want to, they want to make that square peg fit in out round lenses, and they will spend countless man hours on keeping it going for no other reason than they want to and they patented the heck out of it so they can. Sure in ten years (weren't we saying that thirteen years ago when the 400 came out) when DPP can "adjust" for the aberrations in post it might work, but seriously, who cares? When DO is ready  for prime time then bring it to market, I am all for it, in the mean time keep the people who pay the bills happy (us customers) with lenses we want, we need, and we can afford.

I think it is a pretty safe bet that it won't be dramatically different, why? Well the issues it has are at the core of what it is, so it will take a completely different approach, not a Canon strong point, to overcome it, or a different technology like re sampling or a different demosaic algorithm to work around. Something like AA filters and moire, we know what causes it, we know how to have sensors that don't have AA filters and don't cause moire, but we are just not there for a few generations yet.

At this point in time and tech DO is DOA.

Besides I don't want Canon focusing on a lens they make a loss on, and there is no way they have ever made a cent from any DO lens, I want them to make lenses they make profits on then they will have more R&D money and will make even better stuff.

"...DO is DOA"

How do you actually know that!!

If Canon do bring about an improved 400DO it maybe a signal that they have reached the end of the line with weight reductions on the big whites with current designs.
I am sure there would be a big market for a sharp 3kg 500/4DO or a 2kg 300/2.8DO.

Wow! a new 400/4 with ISII and improved optics surely.

Light in weight so tough competition for the heavier 500/4 and the possibility of a good 560/5.6 - probably much better than the 300/2.8 with 2xTc.

It has better dynamic range (if you don't know how to maximise DR in Canon files), but that does not equate to "better image quality", and the 5D Mk III lacks for nothing in terms of overall IQ compared to the Nikon at the image level.


How many of these "Is Nikon better?" threads does this forum have to endure? I mean Nikon paying people for this?

You are a sad person - is Canon paying you?

If we ever get this mythical lens it will quite likely not be 100-400....more likely 70 or 80-400 i.e. very similar in design to the Nikon/Sony equivalents with droopy optics at the long end!

The current optic is a fine example of engineering so let us be thankful.

Lenses / Re: Safari 300 2.8 Mkii or 200-400 1.4x
« on: July 17, 2014, 08:54:24 AM »
This year in October, I will visit the first time South-Africa, Botswana, Zimbabwe and the Victoria Falls. We will do several safari trips during that period. I did already read a lot of gear to use for capturing wildlife. However I stay with the problem of the big white lens I want to take with me on the 1Dx. The 70-200 2.8 mkii will be placed on my 5Diii. Also the 17-40 and probably the 24 1.4ii will go along.

I own a 300 2.8 Mkii, however I see that the 200-400 1.4 is a very versatile lens. Point is of cause the 4.0 max. aperture of the 200-400 against the 2.8 of the 300. On 400mm and 600mm reach they perform almost the same (400/4.0 or 420/4.0 and 560 5.6 or 600 5.6). The extra reach for the 300mm asks for using a 1.4 or 2.0 extender, but changing that is not that quick and I don't like to change a lot because of the dust. For that reason I think about buying/renting the 200-400 1.4 for that trip. Do I need the 2.8 for capturing early or late pictures together with the 1Dx? Or would you use the 200-400 1.4 on the 1Dx for the versatility of this zoom-lens.

What would you do 300 or 200-400 1.4 ? I can't take both because of the weight limit on the airplane.

Any other thoughts or remarks for the gear for this trip are also welcome.

You have ruled out the 400/4 DO IS. Just wondering why - given the low weight advantage of this little prime.

Also, just to point out...there are steep discounts on the 7D as Canon seems to be dumping inventory prior to the imminent release of the 7D II.  That does not appear to be the case with the 100-400L.  There are several possible reasons for that, and one is that the mystical white unicorn will elude us for longer...

That's a very good point - rather than rumours we should be looking for stock levels indicators when older lenses are getting difficult to get hold of.

Accepting what you say then the current 100-400L rumour might be just another myth to tease the faithful - at least for the time being.
