My wife bought me a 16-35 II at the LensRental sale last cyber monday. I'm loving the lens, however there's several nicks in the weatherseal gasket on the back.

I'm aware that this is really easy to replace, however I have no idea where to source the gasket part itself.

Does anyone know where/how I can obtain this part?

Has to be sent to Canon if I am not mistaken. That part is integrated into the lens mount.

but I thought I read that only the 600EX-RT has the AF Assist with a full spread to properly work for the 5d3. That includes the 430EX.

That's also my information and part of why I got a 600rt ... not that I'd buy a 5d3 now after all but a 6d which is compatible with everything, and on which af assist in low light seems to work without problems.

Thanks for the input, everyone. I wound up ordering the 85mm f/1.2 from B&H for $1,799. Apparently Canon's MAP has retailers showing the MAP until you add it to the cart. I usually prefer ordering from Amazon (can't beat prime shipping), but was out of stock. So B&H it was!

Now I just have to muscle through waiting six business days instead of my usual two day free shipping.

I've had them all several times, and it comes down to one thing, what you shoot.

For when my kids were tiny and just layed there the 85 is true MAGIC, nothing comes close. But then they start to move a little bit and the slow 85-AF makes you want to throw it to the wall.

The 135 is creeamy and sharp even wide open, discreet and light. But for me I found that when I was in a situation where it wasn't too long, it was just to short.

The 70-200 have almost everything, blistering AF, with crazy accuracy, the HIGHLY useful (fullframe) focal length and fantastic IQ. The downsides is that it is a beast, heavy and long and forget discreet. But for me that haven't used zooms for years and years, I see now that I crop A LOT because I can't change focal. The 70-200 isn't as long and useless as one might think, it's actually a great indoor focal length for kids ( as they aren't 180cm).

If I could have whatever I want in the lens world, I would absolutely keep the 85 also, the 135 I find is in between what I want, always, so not for me. and the 70-200 is, now once again, a given and most used lens.

Christian...

Now that you seem to have decided on a 300mm....You mention that a friend sold his 300 2.8 to get the 200 1.8, but have you considered buying a used 300 2.8 IS? Just to be clear, the 300 2.8(which is what you said your friend had)was made from 1988-99, and the 300 2.8 IS was made from 1999-2010 AND not only has IS, but also better IQ compared to the original.(and lighter)

I mention this because you can easily find the 300 2.8 IS version used in very good to excellent condition for about $4000...which is a lot less than $6800..and, if you look at the date code on the lens, you might be able to find one that is only a few years old since they were still making it in 2010.

I like Bryan's review over at the digital picture...

Enjoy whatever upgrade path you choose, especially since you say you'll be able to add all of the gear by summer.

Last January 2012, my kit was a t2i with 18-55 and 55-250.

Got a tax refund and wanted a 5d2 kit but not quite enough $$$, so purchased a 7d and 17-55 f/2.8.

Fist year of wedding photography, did over 20 weddings, added oben tripod and ballhead per b&h recommendation (love it). Added rx-100 (saved photo and video at 2 different weddings - love it).

Added 5d2 kit which was quickly replaced by 5d3 kit (love it). Decided to raise prices on photography, even if it means loss of jobs. Just booked most expensive job to date yesterday

2013 is for lens upgrades. I already have Elinchrom strobes and Canon flash with modifiers.

Enjoy and have fun on your upgrade path

Is there any reason you cannot buy a Canon lens mount gasket and install it on a lens without it? If you wanted better protection at the mount at least you would know it would be the proper material as others have pointed out with something like this you won't know until or unless you get one yourself to try.

Click to expand...

The mount is designed with space for the gasket, but, as others have mentioned, the mount is only one aspect of a weatherproof lens.

It might be even worse than that. Many of the consumer grade lenses move a lot of air out the rear of the lens when zooming. Where will it go if the mount is sealed? That is solved in the design of weather sealed lenses, but might just force dust and dirt innto your sensor and viewfinder big time.

I could see that also during a bulb or long shutter exposure forcing dust and crud into the sensor.

One of my needs is for HDR processing, but it's not clear to me what the AEB capability is for the 6D and whether it's flexible and broad enough.

Yes, it is because the 6d will run Magic Lantern with unlimited automatic bracketing.

LewisShermer · Jan 20, 2013

yeah, using the 50mm is probably going to be a whole different ball game than the 28mm which actually gives a lot of play with regards to DOF. even shots that are not pin still have a certain romantic quality about them. I haven't shot a wedding in a few months with it being winter. I think the last one was in september so it's a fresh start for a new year.

I sold the 7D quite quickly but when I called the guy about the 5Dii he'd already sold it!

so I'm now down to just the 5Diii and I've got 2 weeks to find a 5Dii body for £800

anyone want to sell me one?

I trust trust ebay about as far as I can comfortably spit a rat.

I feel a little silly, but that is still way better than if there were a major problem with the camera.

As long as you're only feeling just a *little* silly :-> ... actually my first guess was that the flash wasn't mounted correctly, but then I didn't write it because I thought you'd surely have checked it and when tightening the 430ex2/600rt-type flashes they have to be mounted correctly :-o

ScottyP said:
On the other hand, I wonder if you could "squeek" a little higher sync speed out of the camera (just 1/250th maybe) by deliberately mis-mounting the flash in the hotshoe.

As far as I understand x-sync that isn't possible since 1/180s (on the 6d) is the max. shutter when the first curtain is down and the second curtain is still up, so there is a brief moment with full sensor exposure. On faster speeds the second curtain goes down sooner leaving only a slit that moves across the sensor.

Mt Spokane Photography · Jan 20, 2013

Vik, the light output from those small slave flashes is so low that it is likely just overpowered by the camera flash. Try placing it closer to the subject, or get a more powerful flash. I have one of the low cost slave flashes that came with a used camera and its a bad joke as far as light output goes.

Wildfire said:
I think what he means is that the controls to change AF points are so bad that he is thankful he doesn't have to use them because he only uses the 1 cross-type point.

Ah, right, thanks for translating

Area256 said:
For sports sure, the other AF points aren't so hot, but for portraits I've actually found the outer points to work quite well.

I hope so, because otherwise the "orientation linked af point selection" on the 6d would be a real joke - I'm looking forward to the in-depth dpreview.com review on the 6d for this.

Nice tests.
just as an FYI, the Sigma 8-16mm also works as a FF 15-16mm (although granted, a lot slower than the tokina f/5.6 and it doesn't take filters). 15mm on FF is not as wide as 8mm or even 11mm on APS-C, but it's good to know these 3rd-party UWA can be used on FF in a pinch...

The 135L is one of those primes that really is just a magic black tube with AF. If this lens doesn't satisfy your needs, consider the 70-200LII. Once I got the 135L, I just can't justify the 70-200 unless your doing action all the time.

Click to expand...

+1.

The 135L is in a league of its own.

Wildfire said:

I owned the 70-200 2.8 IS II for a year and it never left my 5D2. I took it out on walks, I took it to the park, I took it to weddings. I never thought that it was so heavy that I wanted to trade it for the F4. Never.

The 70-200 2.8 IS II performs almost as well as the 135L and includes 70-134 and 136-200 as well.

Click to expand...

This is not exactly accurate... in fact, the comment the zoom on top of 135mm "includes 70-134 and 136-200 as well" got me laughing. It is like those awful TV commercials "Wait, wait, that is not all!!!...if you call now... you will get on top of the toilet scrubber, this great self cleaning pink toilet brush !!!"

The 70-200 II zoom may cover the 135mm range, but the 135L prime is compact, faster than the zoom at f/2, and above all, incomprable in IQ even wide open.

The 70-200 II may well complement the prime nicely, but by no means is it a substitute for the 135L.

Hmmm, interesting. I can tell you that at f/2.8 and narrower, you'd be correct in that they are incomparable in IQ because there isn't any difference at all. The only advantage I'm noticing, and I shoot with both, is the extra stop of light on the 135L. Other than that, IQ seems exactly the same and I can't tell a difference. As a downside, it AF's slower in sports than the zoom. On the plus side it's razor sharp wide open at f/2, and that's a place the zoom can't go. I'd argue for sports, the zoom is a fantastic substitute, but in all other cases I agree, it is not.

DR is not a hype it is a fact and it needs skills to use it , no one will have less DR or a lens with lower resolution
Hello, can I have a 300/2.8 MK3 IS with lower resolution- please

The DR itself is not hype; I never said that it was (read my post again). However, much of the discussion surrounding it definitely involves a lot of hype and tends to raise a lot of unnecessary FUD. What is a fact is this: With a few cameras, you will get two additional stops of noise performance in the deep shadows when you dial the gain in the camera to ISO=100. If noise is really your concern, you will always do better with a multi-shot approach, in cases where you can do so.

DR should be looked at as a feature, just like a 100% VF, In-body IS, Tilt screen, 61 point AF or any other of those things that you may be considering. You need to figure out where it benefits you and where it does not and then determine how much it is worth in any decision you may be making. It doesn't affect the general IQ of the camera (this is where the hype generally creeps in), just a small set of corner cases that may or may not be important to any given photographer.

I'd have no problem with storing 36MP files, or even 60MP files for that matter. No problem with processing them either.

Click to expand...

Actualy, the 50 mp high ISO images decompress to about 150-200mb, and they are a pain to post process, particularly with brush adjustments in LR and adding NR. I've processed 700 images from a nights shooting with my D800 and with a reasonably fast computer, and it takes much longer to post process than a 22mb 5D MK III. Storage is not the issue, its cheap, but having to change CF cards twice as often is a pain. I finally bought 64mb cards to help with that.

Storage is definitely getting cheaper.... I remember when hard drives dropped below the $1.00 per kilobyte level. Now it's around $1.00 per 20 gigabytes... And I have a drawer full of 32Mb compact flash cards at work.....

As to processing speed, GPU assisted programs are slowly finding there way into use. By using the graphic processor you can execute parallel tasks off of the main CPU, and depending on the nature of the program and data, can speed things up by a factor of ten or more. A good example of this is Autopano Giga, which can use the CUDA cores on an Nvidea graphics card to speed up rendering of panoramas. A high end card has 1000 1Ghz CUDA cores... Lots of computing power. There have been supercomputers built using graphics processors.

I would expect to see GPU processing getting more common in software as time goes on.

I should add, that I/we have also got a third party wireless trigger off ebay (see http://www.ebay.com.au/itm/251175507175?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649), so that isn't an issue, but for indoor macro set ups will prefer to use the 7D and 600D master optical controls so as to take advantage of the TTL function seeing that our extension tubes provide metering.

I am already thinking about a 600 EX-RT (as well as a 430 EX II) to future proof at least one of our flashes.

I know, but since Canon's external gps unit contains an electronic compass I don't think it would have been impossible to also put it into the 6d camera - they managed to squeeze in gps and wifi after all... just the location information simply is underwhelming to me since imho an external logger is better for this.

I never cease to be amazed at what features get included and which are left out..... And not just with Canon.

Can I use the Yongnuo YN622c on my 5D3 with 580EXII? This sounds like a viable, low risk solution to the low-light 5D3 AF blues.

East Wind Photography · Jan 19, 2013

So as explained the AI servo is predictive. It will adjust focus based on what it tracked previously. The subject may not be on any AF point when the shutter fires. The AF points are used to complete the math for when the subject is not on an AF point. It's not just tracking what's on an AF point.

Most people don't understand what's going on in the background when they select one case or another and tnhen blaim the camera is not working right.

Click to expand...

I haven't been working with it long enough to blame the camera for anything yet

The gist of my initial inquiry is: why doesn't the camera SHOW you what it is tracking because it evidently IS doing it anyway? The shots and metadata show it.

The answer seems to be: it will, but only in selected modes... opening a different can of worms: why?

Case #1 didn't handle the same scenario very well (though I've since learned quite a bit). Case #6 is the next I tried because it "fit" the description of the shooting scenario the best. The results confirm that. A very high in-focus hit rate. It remains to be seen if zone-expansion was a factor in that success.

Since then, I've tweaked the Case#6 settings a little AND set the camera to FOCUS priority. Next shoot, I'll try those settings an then various combinations and permutations on them. Considering how little time I've spent behind the viewfinder, it's taken remarkably little time to start producing decent shots. Mostly because I'm still at the steep end of the learning curve, NOT because of any inherent limitation in the camera. In fact, unless I see something impossible in an image, my natural assumption is "I'm doing it wrong."

I'm trying to learn it step by step, section by section. The lenses are all AFMA'd now (FoCal). Now my head is starting to wrap itself around the AF. I don't think I'll be moving from Av/Tv/AutoISO to M any time soon though

Don Haines · Jan 19, 2013

I am interested to see what the effect of touchscreens will be as the technology matures and poeple find out what ergonomics work and what does not.... but there is one really good reason to keep the multiple wheels and buttons and shoulder displays of the "pro" cameras..... you can operate the beast by touch and don't have to take your eyes off of the viewfinder.
