No worries GMC, we agree, I just wanted to moderate the very negative overtone of your previous post.

Of course extenders are not as good as native primes. But for the hobbyist that will never buy a 400 better than that, having better results/possibilities with extenders are something to take into consideration too. That's all :)

Sorry if you felt my reply was negative, it usually quite factual which can voice as a bit cold on forums. No offence were intended or implied and i'm quite freindly really. The 400 f5.6L is a very cost consious lens and very capable too. It lacks a close MFD and IS system but optically and from an AF point of view, it's a fantastic lens which often gets over looked. 

Just to push the conversation on a bit. The 1.4x TC on the f2.8 II L version is interesting too, it pretty much negates the need for the 300mm f4 LIS. The combo is just as sharp, AF is just as good, it's IS is superior and it zooms too.

It isn't difficult or that time consuming to make your own with the free Adobe Lens Profile Creator.
I remember they had really detailed instructions about this when they first released it, but I never got around to trying it.  Have you made some?  If so, I'm guessing the results are pretty good given that it's a profile of your own lens+camera combination.

Does it need much adjustment? I thought this lens was nearly perfect :D

I've used a 70-200 f4 LIS with a 1.4x many times. It becomes an effective 100-300 f5.6 LIS with simular optical charectoristics to the new 70-300 f5.6 LIS. Sure, if you want to use a 2x tc you will need a 5DIII or 1Dx and only the centre points will work....but even with the f2.8 LIS II version, the 2x is pushing it a bit and the AF is pretty slow and ponderous.

Never used the 1.4, didn't remember the aperture reduction was lower. Thanks for the reminder.

of course I never used a true big white to compare but I was very pleasantly suprised by both AF and IQ during a recent outing (rugby game, sideline, fast wingbacks coming at me). Clearly didn't fail me.

I recently compared my 70-200 f2.8 LIS II with a mkII 2x teleconverter with a 100-400 f5.6 IS L. The IQ was very good from both lenses. The 70-200 combo has more vignetting and softer corners. It was heavier and more unweildy too. Slightly longer focal length too. The IS usnit was clearly superior and the AF was a tad faster, which really suprised me. It's an effetive combo, but compared to the 400mm f5.6 L there is little comparison. The prime is sharper, less vignetting, CA etc, it's AF is snappier, faster and more accurate. It was far far lighter and a lot easier to use...but slightly less versatile.

It would be awsome if Canon can make a 70-400mm which has the IQ and AF speed of the native 70-200 f2.8 LIS II.

I recently had some unplanned cash at hand and upgraded the 4 IS to 2,8 II IS.
Although pretty much razor sharp, sometimes the 4 did limit my exposure time - I know ...this is post-hoc rationalizing for GAS
I really see a difference in autofocus performance on my 5D3, and I can make good use of the additional weight for training purpose...

Bottom line: If IQ is your driver, 4 will get you there. If weight and shooting time per day may be a limiting factor, don't go for the 2,8. It is substantially heavier more than double the weight and very obvious (no really for candid portraits)

If you are strong and committed to weight lifting -go for it, it is sooo cool...

With the 4 you have no room for extender. It's f8 and bump iso or f8+ and MF. 2.8 leave you much more headroom.

The faculty to be useable with a x1.4 or x2 is a point to consider (what's not to love in a good 140-400 f5.6 for 400 bucks? -once you already have the lens that is-)

I've used a 70-200 f4 LIS with a 1.4x many times. It becomes an effective 100-300 f5.6 LIS with simular optical charectoristics to the new 70-300 f5.6 LIS.

..Neither have direct equals in other bands which says a lot about the quality of these lenses.


uhmmm..  the Nikon 70-200 f/4 VR may not be pro quality build but it's optically quite a good performer and is, for example, one of the better lenses to use on a D800e for maximum resolution.

So there's one.

And the Tamron 70-200 f/2.8 VC is no slouch either, turning in a similarly good performance.
That's 2 other options or at least one if you want an EF mount.

As I said, there is no direct equal for either lens. While the Nikon version is a match optically, it's build and application are not Pro build. As I said many times before, there is more to a lens than it's optics. Just becuase Nikon have made a lens with the same optical formula, it doesn't make it the same lens.

I have actually thought about getting a 400 mm f/4 prime (big white that unfortunately does not exist)

http://www.canon.co.uk/For_Home/Product_Finder/Cameras/EF_Lenses/Telephoto/EF_400mm_f4_DO_IS_USM/

Another option is a 200mm f2.0 LIS with a 2x converter or a better option is a 300mm f2.8 LIS mkII and a 1.4x TC....makes a great combo.

Here's a few of mine:













There's Eagle Owls, A Snow Owl and a long eared Owl.
All taken with a 5DIII or 7D and either a 70-200 f2.8 LIS II with a 1.4x TC, 400mm f5.6L or a 400mm f2.8 LIS and a very sturdy tripod.

Yep, optically there is little between them too.

If it's more than 150 on the wide end, then I definitely won't be interested.  If I want a narrow range of focal lengths, I'll get a 400/5.6.  I want a zoom because I need a zoom.

Sony makes a 70-400.

Yep, the 100-400 is an odd range, slotting in with a 24-105 as it's only option. Which is a really old lens and really needs an update. The 24-70 lenses have 70-200 and 70-300 partners.

While this shot may not look it...it was taken in really strong head wind. My pod was low and the spikes embedded in the bracken. It was stable for a long exposure in the buffeting wind:


Exif says 240 second exposure. It's pin sharp and I'm not sure an IS equipped 16-35 f4 LIS would have gotten the effect I was after ;D

Lenses / I feel vindicated by this post about the 120-300 Sigma
« on: July 02, 2014, 05:27:54 AM »
I have to say, I feel more than a little vindicated by this following post about the 120-300 f2.8 OS from Sigma:

http://www.canonrumors.com/2014/06/the-saga-of-the-sigma-120-300-f2-8-os-sport/

I had a copy of the previous (non art) version which is the same lens optically and mechanically. I took it to Ireland to photograph Irish sea birds and I was astonished how lame the AF system was compared to my 70-200 f2.8 LIS II, even with a 1.4x TC. It couldn't track a bird in flight, it would lock and then loose AF. It was hesitant and unreliable. I had high expectations of this lens, but I soon sold it once I returned to the UK in disgust.

The focal drop at MFD was appalling too. At MFD, which one would use to try and diffuse the background of a sitting bird, the focal length dropped alarmingly short. Around 240mm by my estimations, far below the 300mm stated and not much different than my 70-200, which doesn't focus breathe. It's a heavy lens for sure and not really worth the bother for the results I couldn't achieve. Where as the 70-200 f2.8 II L and a 1.4x nailed this shots every time and really showed me how bad the Siggi was behaving. These Siggi lenses really are no match for Canon's finest L's. I currently use a 400mm f2.8 LIS and I look back at this Siggi as a tragic error of judgement on my behalf.

57
I don't know where you heard that the 120-300 was better than the 70-200, and I seriously doubt it's as good as the 300 f/2.8 IS II.  Just look at the charts against the 70-200, it's no contest IMO.:
http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=381&Camera=9&Sample=0&FLI=1&API=0&LensComp=687&CameraComp=453&SampleComp=0&FLIComp=3&APIComp=0
Even with the 1.4x extender the 70-200 is noticeably better.


As for the 120-300 vs. 300 f/2.8 IS II, again, no comparison.  Even at f/8 the 120-300 isn't as sharp as the 300 at f/2.8:
http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=381&Camera=9&Sample=0&FLI=2&API=0&LensComp=739&CameraComp=0&FLIComp=0&APIComp=0


That is not the lens I am talking about, this is a much older design by sigma which did not even have IS ... the new one is a completely different design and much improved

The AF capability of the Canon 70-200 f2.8 LIS II and 300mm f2.8 LIS are in a different league to the Sigma 120-300 f2.8 OS. The Siggi is a nice lens optically but it's over sized and too heavy for what it is and it's focal length reduction due to breathing is rediculously bad. At minimum focus, the lens is closer to 240mm than 300mm, which to be honest it's that much different than the 70-200 at the long end (which doesn't breath like this).

Lenses / Re: Waiting for the 35 1.4L II
« on: July 02, 2014, 05:10:59 AM »
No doubt, sigma 35mm 1.4 art is canon killer.

Check some reviews, many people compared the two lenses. Though I'm not quite sure about the build quality that Sigma provides — at first sight yes, it's very good, but will it last as canon 35mm does?

I'm not sure I'd call it a Canon killer....it's a little bit sharper but that's about it. Also bare in mind that I've been using my 35L for the last 8 years (and it's paid for itself time and time with great professional images) where as this Sigma is new to the market. I'm happy with my 35L and see very little reason to swap to the Sigma. My Canon 35L has provided great images and will continue to do so.
If you rate a lens by optics alone then sure the Sigma looks great. But I would wager in a comparison that few could tell from an A3 print which lens was which. The Canon is far better built, has a far more reliable AF system and will hold it's value on the second hand market over the long term. Sigma AF issues are well documented, even their 120-300 has af issues.

Either the 70-200mm f2.8 LIS mkII or the 70-200mm f4 LIS are pretty much as good as it gets in the optical long zoom category. Neither have direct equals in other bands which says a lot about the quality of these lenses.

Lenses / Re: Review: Canon EF 16-35mm f/4L IS
« on: July 02, 2014, 04:51:23 AM »
The IS will be nice for anyone using this lens without a tripod and the video crowd will dig it, and it's the only Canon UWA zoom that's ready for a higher resolution camera. It's reasonably priced. What's not to love?

What's not to love?

The price of course! It should be cheaper by $200 - $300 :)

Will the street price drop over time? Hard to say but for a lens that is reviewing so well, why would anyone feel the need to drop the price? People want it already at the current price!

It already has! Canon (apparently accidentally) marked it as valid for the 20% off discount thing they held some weeks ago. So a few of us did get it for $200 cheaper  ;D.

Try the UK then. It's still sold everywhere for £1199, which is $2056!

Canon UK ramps up the UK RRP expecting the UK shops to discount heavily. But when a new product comes out, most shops sell it for the max RRP, pocketing the difference and effectively penalizing new to market gear.
When the 70-200 f2.8 LIS II hit the market, it was only available for £2500....which is silly money. So I waited  about 9 months and picked up one for £1549. So my advise with the UK market is to either buy abroad or wait. If you buy new to market kit in the UK you are only feeding the greed of the UK shops and letting them get away with it.
It's your money and your choice at the end of the day, but I've found most UK Camera shops to have questionable behaviour. They charge these crazy prices because people will pay them.
