If I recall, doesn't Canon specify the use of a filter to complete the weather sealing for this lens?

I've seen this on other forums but there doesn't seem to be a definite answer on this. I've never put filters on and never will. Personal choice but I don't consider the protection of the front element is an advantage compared to the disadvantage of another piece of glass in the way, however good it is.

Interesting. I can't find an actual reference to the need for a 'sealing' filter myself now either, but I'm sure I read it somewhere when I was researching this lens prior to buying one.

Anyway, mine currently has a clear protection filter on it for the time being and I'm quite happy with results so far.

This article is the one where I saw a reference to needing a filter to provide full sealing...

http://www.the-digital-picture.com/Reviews/Canon-EF-100-400mm-f-4.5-5.6-L-IS-II-USM-Lens.aspx

"Designed for outdoor use, the 100-400 L II features a weather sealed design. This lens is not waterproof, but it is made to be used in wet and dusty conditions. Specifically, the manual states "Tight seal structure provides excellent dustproof and drip-proof performance" but then disclaims that sentence somewhat by stating "However, it is unable to provide complete protection from dust and moisture." Chuck Westfall of Canon USA has confirmed that a filter is required for full sealing of this lens."

Thought I was going mad, but saw the review again the other day and thought I'd share...
 
Is anyone experiencing a loose joint on the tripod lens collar at the join between the removable tripod foot and the collar, please?

There have been numerous reports of the problem online but what are the effective solutions? Where can one buy a JIS screwdriver?

A replacement third-party foot such as by RRS? An allen key screw is probably stronger than using finger-n-thumb as Canon's method.

Looking at this Robin, using an aftermarket foot like the RRS doesn't solve the problem of the black square base coming loose. The base carries the thread for the foot, if you remove the base there isn't a thread to screw into.

JIS drivers are fairly easy to get hold of but they tend to be dearer than normal ones.

I've not had the problem but if I did then a drop of loctite would be my solution. Not the permanent stuff but the stuff that you can break out if needed.

Sorry, can't help. I've got about 20 or 25 of these lenses and none of them have experienced this issue.

....Thanks, Gary!

I hadn't realised that the black square plate with its rather small JIS screws held the worm thread. Your suggestion of the right Loctite sounds like the best solution - Thanks!

....I have had my lens for several years now and use it a lot, exclusively for wildlife photography where I am carrying it using the lens collar foot (with long arca-swiss plate attached) as a handle.

Googling the problem throws up a lot of reports of instances. Some say they have solved it with Loctite and others claim with an aftermarket foot replacement although as Gary has now explained, I don't see how that would solve the issue.

Cracking lens but when using the 1.4x converter some of my images are soft
Click to expand...

....Are you using the latest version III of the Canon 1.4x Converter? To do otherwise is not recommended.

I have never found it consistently soft but long distance images taken at 520mm can have a soft tendency according to lighting circumstances and therefore contrast and ISO.
 
Changed mine for the 400mm DO MKII combined with the MkIII 1.4 converter on a 7D Mk II as I use the longer focal Length more, Superb.
For the rest the 70-300L comes in nicely.

How are you all finding your Canon 100-400 II after a couple of years using it ? This thread went a bit quiet.
Click to expand...
I've only had mine a few months, but dare I say, I find it equal to, if not better than my previous "favorite lens" the 70-200 is 2.8 mkII
I was reluctant to go to a f/4.5-5.6 lens, but certainly coupled with the 7DII I have no such qualms ( regarding ISO handling) (y)

I'm really in 2 minds at the moment. I have a Sigma 150-600mm sport but tend not to use it much because of the weight but I have the 70-300mm L for travelling light (ish).
I would definately miss the 600mm but if I sold both lenses and my MKI 7D I could just about get a MKII 7D or 80D and the 100-400mm and unlike the MKI both bodies would work with the 1.4x giving 560mm.

Most places are giving 10% off L lenses this weekend plus factor in £215 Canon cashback and we are in grey area for a UK lens with 3 years warranty.

I don't know anything about the 80D but the 7dII was a large leap from the MKI,
and it seems your'll save about 1Kg weight with the 100-400.

Everything's a compromise, but as compromises go, that's a bluddy good one. Such a versatile combo :)
 
The missus just picked up an 80D and the additional f/8 focus points come in handy for the 100-400ii + 1.4xiii. I prefer my 7DII, but 80D is a really good camera.

I borrowed a 80D for a week a while ago and while the 7DII is (I'm sure) the better sports camera I do a fair bit of macro and the variable screen came in very handy.
 
Been using mine virtually from when they were released, it's been back to Elstree once for a service, and been in dusty environments for extended periods (India, Africa etc) and is simply superb.

Coupled with the mk2 1Dx it's nicely balanced and with the iso performance of the body, the 5.6 (and indeed sometimes f8 with a converter) isn't a problem.

Am I right in thinking that the extender would only work with the centre focus point at f8 on my 80D?

From looking at the spec, I think I'm correct in saying you have 27 of your 45 af points available at f8......

That's correct. On the 7DII I can use the centre cluster with the1.4x converter on. With the 80d a whole bunch (that's just a handful short of a plethora) of focus points are available.

Isn't it lens/extender dependant i.e. they work with some combos not all, appreciate we are talking about 100/400 MK2 but I believe it needs mk 3 extender and not sure about other lenses.

80D, MkI/2 converters only give centre point. MKIII give 27 with he centre 9 cross type. With the 7D2 you get centre cross type plus one around it to form the cross irrespective of which converter you use.
 
If Frankly, if you are going to the expense of a new 100-400 mk2 I wouldn't consider anything other than a mk 3 T/C.
