Canon Rumors did a review of the 70-300 f/4.5 to f/5.6 L IS, and was one of the factors which caused me to buy one. I still have the 70-200 f/4 IS - have not had chance to do an A:B comparison yet. Couple of points

a) For a bizarre reason, Canon chose to swap around the focus ring and the zoom ring, so you sometimes chose the wrong one. It's not a biggie, but worth knowing
b) The 70-300 f/4.5 to f/5.6 L IS will not work with Canon extenders - designed to prevent this. Does work with the Kenko Pro G teleconverter (again have not had chance to try comparison of with/without).
c) I've not tried this for fast moving action, but you could hire / try either of the 70-200 lenses with a 1.4x to get additional reach at the expense of some sharpness / some focus speed.

Indeed.  The reason might be a design necessity (for example, the lens has a floating focus element), but may also have been by choice.  From their market position paper on the lens, Canon is aiming it primarily at APS-C users, and even though the zoom and focus ring placement is reversed from other L-series lenses, it is the same as the high-end EF-S lenses (17-55mm, 15-85mm, 10-22mm).

Cool - never realised that for EF-S lenses Neuroanatomist - definitely a mild confusion with the other lenses I use.

Whilst everyone jumps in with the biggest most costly options, a lower cost option is the 70-300mm non L, which although isn't great in low light, works fine for me in terms of getting the occasional long shots - it has IS which helps, but for less than the price of the 70-200mm f4 and half the 70-200mm f4 IS

but it´s not parfocal (same as the 70-300mm L).
thats not so good for spotting.

thought the 100-400 is not parfocal too.
at least not all copys... i had a few who are parfocal but more are not.

Course it is ;-) it's called autofocus !

Seriously though, I'm not familiar with lenses that are parfocal, so what I haven't had I never miss...   Whilst it's easy to dismiss a lens because of a single feature, many of us don't have the disposable income to invest in lenses that cost as much as the 70-200mm f2.8 IS, let alone the longer fixed primes, regardless of how much we would like to.  It's easy to take a X is best approach, but the reality is that practically all purchasing decisions in life are a financial compromise.  Personally, I don't use my 70-300mm that much, so don't feel a strong urge to get a better lens in that range, I'm more of a wide and/or low light photographer, so I'm starting to expand my collection with that in mind, the 70-300mm was bought at the time I got my 450D about three years ago, the 15-85mm last autumn, the 50mm f1.4 a few weeks back, I'm now pondering wide low f, the 16-35mm would be nice, but I suspect the 28mm f1.8 might be all I can justify, maybe a 17-55mm at a stretch...   Watch this space, but gawd do I want Canon to do some wide fast EF-S primes !

Canon has released patents now for a rear focus design with multiplee elements moving in a complex pattern.  apparently they discovered this as a way to improve the IQ, and we will see more of this.

Some lenses are front focus and some rear, its been that way for many years.

Thanks for all the answers.
At this moment i have a EFS 55-250 IS and the zoom range works fine for aircraft taxing and on take off roll, this is in my nearby airport OPO. The big disadvantage for me of the EF 70-200 f2.8 is the weight, a couple of hours with that on my arms  and at the moment i have a 500d so a big lenses with a small body don't know.... The IS in the lenses is useful for me to trie some new shots and because i use my camera 70% for plane-spotting and the other 30% for travel or general photos.
I'm also a big fan of the EF 100-400 L IS but its an old lenses that someday would have a replacement? I also been searching stuff about the EF 70-300 L IS and it seems to be good material, at this moment my budget its around €1100 so i'm seriously thinking about buying the EF 70-200 F4 L IS and later with more € available and a new body i would like to have a lenses like the EF 100-400 L IS and the EF 70-200 f2.8 L IS II

Best regards

In our single airport in the country, there is a particular spot for plane-spotters, and I do go there sometimes just to watch them, and the planes while eating something. Most of them use any type of lenses, and even smaller cameras. 70-200, 100-400 and 70-300, 55-250 are the most common, and pretty much every lens seems to deliver for them. They told me that usually their objective is to collect the different planes including different serial no's, and that sometimes they only shoot the serial numbers or stickers.

I have seen your photos and it seems that you are doing well with your setup.  Do you have a particular shortcoming with the 55-250 for your needs ? I am asking as this can help you further, to decide what's best way forward.

Hi,
Well I'm a plane spotter that likes to do good photos off an aircraft, i don't simple collect registrations i prefer to have good photos with quality. About my actual lenses I'm very happy with it but now i would like more image quality, more sharpness and better colors, i also could use about 20% of times more focal length to get different shots...  I think that buying an L lenses, and with proper care, its a lenses for a lifetime and i can get better shots.

I like to go out by a back gate of a regional airport and take photos now and then (I haven't had a chance to do it with the 120-300mm f/2.8 and 2X III extender setup yet), in addition to chasing around aircraft that overfly the yard.  A good picture is my goal.

I actually had to think a bit about which is better - zoom ring or focus ring in front - and with a heavy lens like the 120-300mm f/2.8 you really want both to be in front.  Probably, with a better AF system and/or uncluttered scenes (i.e. not shooting into tangles of branches) you probably want the zoom ring in front because you can recompose the scene and let AF do the rest.  Trying to track a subject and recompose while balancing the lens halfway back and zooming seems like it would be too straining.  Grabbing the focus ring isn't easy, either, and you still have to balance it, but at least it can be done.  For me, using that particular lens, the problem is that my usual AF mode means that the camera keeps trying to track despite my grabbing the focus ring, so I usually have to flip the AF/M switch regardless of what I do.  Putting the focus ring out front wouldn't make that more convenient.

If more sharpness is what you want, then the lenses you are considering are all good. The 70-200 4.0 IS is considered the second sharpest from the five 70-200's. You are right, buying an L lens is valuable. I prefer to buy Canon lenses due to the good investment. You certainly not throwing money by buying any of these lenses.

Not considering the 10-22mm EF-S f/3.5-4.5 at half the price of the more expensive 16-35mm L EF f/2.8? Unless you only have a FF, or shoot exclusively wide and low light at the same time of course... I prefer the 10-22 for sharper corners and a decent dof - not as good as I would like, but good enough for the price.

Nice. Although I take a lot of airplane photos, I'm sometimes in them as well.

Wait, are you talking about the EF 70-300mm f/4-5.6 IS USM? 

I've been sorely disappointed time after time by this lens; grainy and low-res compared to pretty much every other lens in my collection  

We went up to Alex Bay last weekend and I have to say that the 70-300 shots were so grainy even on a 13" notebook that recomposing the shot and using the 24-105L seemed much more professional . . .

I'm definitely in the market for a higher quality telephoto.
