Technical Support / Re: Canon 600D, Sandisk and Corrupted MOV files

That's a story that is all too common.

I prefer to buy cards from a reputable camera store, but will buy ones that are sold by Amazon, but not a third party unless its a store I know.  Adorama, for example, sells on Amazon, but not thru the Amazon Prime.

Chinese sellers are getting clever, and shipping stock to Amazon to sell on their Prime program.  Most of them are honest, but counterfeit batteries and flash cards are so common in China that it can be difficult for a buyer to know who the real seller is.

This is good advice. If you're buying anything that could have a counterfeit issue on Amazon, make sure it's shipped from and sold by Amazon.

EOS Bodies / Re: here we come, 6d AF problems
« on: August 12, 2014, 05:24:33 PM »
Actually all I can share is that quite often my camera can't focus on wide angle, but when it locks everything is just fine. It's not connected with anything like shutter speed, it's only AF system.Besides, I was told by one technician that this is impossible to repair, though I'm not sure now that he's competent.
I'm gonna AFMA it this week, hope it'll help.

I wish you'd be a little more clear with your problem description. So far I think you've described two very different problems, one with a 35 f1.4 lens, and another with a 16-35.

I might be reading a little too much between the lines here, but it sounds to me like you can't even lock focus with the 16-35? In one shot AF mode, I would expect that to only happen if you're shooting at a very low contrast target (white wall, clear blue sky, no light etc) or closer than the MFD.

If that's the case, I'd send them in, with a clear description of what you're doing and what's going wrong.

I actually noticed that the problem I described appears only when I use wide angle lenses

The wider the angle, the bigger the problem — when I go to 16 on 16-35 it becomes totally obvious that something is wrong.

You haven't even addressed whether you've tried to AFMA your body/lens combinations.

Maybe you could post some full res samples of your issues, or at least answer some of the questions that have been posed. If your problems are increasing as you go wider, I wonder if you're not keeping your shutter speed up enough.

What I can tell you is, a 5d3 isn't likely to solve your issue. There's a very small chance that your 6d is broken, but you'd save a ton of money by getting it repaired instead. There's a slightly larger chance that a 5d3 will just happen to be better suited to your lenses, as far as manufacturing tolerances go, but that also is unlikely. Odds are highest that you either need to AFMA or you're making a technical error while taking shots. But if you don't share more information, nobody here is going to be able to help you.

Thanks, candyman, Northstar and Valvebounce!

There are so many amazing shots on here. It drives me to work at improving.

No shipment email here either. I found out it was coming when I got an email from UPS thanks to MyChoice.

It's finally shipped! Tracking says it should be in tomorrow. Yay!

Thanks for the information, Besisika, it gives me hope. I'm sure that, with that second production facility, the wait times will shrink soon.

ifp, I'm guessing you ordered soon after that review appeared here on canonrumors? Same here.

I've seen a few different reviews, though I think it was AlanF's comments on here that ultimately persuaded me. I actually originally ordered it in February, had a trip in March and contacted B&H who estimated it would have arrived while I was out of town so I (stupidly) canceled. I reordered during my trip, thinking it'd be a month and now it's been almost 3.

I ordered one in March from B&H too. Every email I get I hope it's the shipment notification. Of course, they're closed for the next few days. I really want that lens, I've had a few opportunities where the extra reach over my 100-400 would have been very useful.

If you're particularly desperate, you can overpay on ebay...

I placed an order for it on 4/1 from BH so I'd have plenty of time before a July trip - haven't heard anything yet.   Status is still "On Order".  I wonder what the current lead time is.

there is a quite a backlog for them as they are super popular

Mine's been on order since 3/11. I had actually originally ordered it in February but was going to be out of town the week of their estimated shipping date (I got in touch with their customer service to find that out), so canceled my order. I should have asked if they could move me back in the queue instead. Oh well.

So thats why the 6d has pathetic battery life compared to any rebel or the 60d. great :(

My 6d's battery life is just fine. I don't leave GPS enabled unless I'm actively shooting, and I rarely use the wi-fi. The other day, with GPS enabled, I took 1300 shots on an outing (yeah a bit of spraying and praying...) and had over 50% battery left when I got back.

With more sporadic use, I find I easily get 400 or so shots before I charge the battery. I usually charge it when it's around 50%.

So if you're getting pathetic battery life compared to a Rebel (I have an XS, and it does not compare), then I'm guessing your 6d is defective. Either that, or you leave GPS and/or wifi on...

Have you the Tammy? Can you contribute for anything here at all?

You said it. You don't own it, and you've rejected the postings that are contrary to your opinions from owners of the lens.

In the case of the 1D X, you have 6.95µm pixels, or an area of 6.95^2µm: 48.3µm^2. The 7D has 4.3µm pixels, or an area of 4.3^2µm: 18.49µm^2. Again, because were working in two dimensions here, it's not a linear scale, you can fit 48.3/18.5 7D pixels into one 1D X pixel. That comes out to 2.61x 7D pixels per 1D X pixel. You would need a 2.6x TC in in order to completely normalize the crop difference between the 7D and 1D X, all else being equal.

Wouldn't that be a sqrt(2.6)x teleconverter? Every teleconverter I've seen lists their focal length multiplier, meaning a 2x teleconverter puts 4x the pixels on a target.

Back to the topic, I'm interested in AI Servo performance of the Tamron. I really want to try to get a hold of this lens for a trip in March, but I'm a bit concerned by the varying stories I've read regarding AF in servo mode. I have a 6d so for it center point is really all that matters. I would like to purchase a 5d3 eventually though, so if the lens is not going to behave well for other AF points (I've read it's fine and I've read it's useless except for the center point) that's a bit of useful data to consider.

Have you tried a different SD card?
