1dx file name error *Solved*

This is not a Canon thing, its a industry standard.

Canon complies with the industry standard Design rule for Camera File system. JEITA specification number CP-3461

it requires that the first digit of the file name be a leading underscore for files with a optional colorspace such as Adobe RGB.

Is there something wrong with my 600 EX-RT (or myself)?

neuroanatomist said:
Sounds like the modeling light (high speed pulse lasting 1 second). Could you have been (accidentally) pressing the DoF Preview button?

You're 100% correct. I just tried to take the picture next to the lights without and with pressing the DoF Preview button. In the former case it behaves just fine, in the latter one it does exactly as I described before. Thanks so much for your help :) so much yet to learn… :)

NYT: Only Canon, Nikon and Sony will survive?

Interesting article from December 20. Says smartphone selfie-shooters are not embracing the mirrorless bodies in the way it was hoped they would take to a somewhat smaller setup. Perhaps they will eventually leave off trying to make a "kinda smaller" camera that is too small for most serious shooting, but still too big for selfie-phone man, and keep making cameras that are the proper size for 2-handed shooting.

Also says the Big 3 will endure but the also-rans like Panasonic, Pentax, Olympus, and even Fuji don't seem like good bets going forward.

Personally I hope Fuji at least makes it. Original sensor tech and an elegant package.

New Years Eve!

Happy new year CR!
I figured I'd start a thread where we can share our NYE stories and photos. I ended up at a hippie music extravaganza with acts like Splintered Sunlight (photos below - a Grateful Dead tribute band), the Jerry Garcia Band (minus Jerry) and the New Riders of the Purple Sage. Not my normal gig but a fun time nonetheless. Here's a couple photos:

New to Canon - please help me decide on lenses

Mr_Canuck said:
Well, I've made my decisions. I have ordered a 6D and a 40/2.8 STM (had to try it, for $129) which are waiting across the border for me to pick up next week. I picked up a nice used 70-200/f4 IS already but it's fairly useless so far without a body.

Good choice. I think you'll like the shorty forty. It was by far the best lens you could find in its price class even at $199. Now, it's just a steal. I ditch my battery grip and use that lens when I want my giant DSLR to seem unobtrusive, and most of the time, I feel like I could get away with that lens, a 16mm prime, and my 70-300L if I had to limit my lenses for some reason.

Lots of New Lenses Coming in 2014 [CR2]

Isn't the new Tamron 70-200 f/2.8 almost as sharp as the beloved Canon version?

Not from what I've seen. The new 24-70 VC comes somewhat close to the Canon 24-70 II, but there's a bigger IQ gap between the 70-200/2.8 lenses. I'd bet that the new Tamron at 600mm won't be as sharp as the current 100-400 at 400mm, and since you mention a $3K lens you must be referring to the pink unicorn 100-400 II, which if it becomes reality, I'd bet that lens at 400mm cropped would beat the Tamron at 600mm easily. Then there's the issue of AF speed, something Tamron lenses aren't known for...

Many people buy the 70-300 non-L over the 70-200/4L because the former is 100mm longer, has IS, and is a bit cheaper. If they cared about IQ, they'd be better off cropping images from the shorter lens with much better IQ.

I think the Tamron 150-600mm will be reasonably popular, because it'll be a cheap 600mm lens. But there's no free lunch, and the price of this one will be IQ.

Time will tell. But no matter how "sharp" the new 100-400 is, you won't get more resolution from cropping an image shot at 400mm, as shot with the Tamron at 600mm.

That isn't true at all. Depending on how good the quality of the Tamron is, it could very likely perform poorly enough that its 600mm end that the Canon at 400mm is as good or better. The lens' resolving power is ultimately determined by aberrations and aperture. At the very least, the wider f/5.6 aperture of the EF 400mm lens would give it a diffraction limited resolution (~123lp/mm MTF50) edge over the f/6.3 aperture (~104lp/mm MTF50) of the Tamron 600mm. At the very least, your losing about 15-16% due to diffraction with the 600mm lens. There are also going to be compromises in order to support the zoom range. For this lens to fit into it's cost bracket (i.e. reasonably cheaper than the Canon), you have to figure Tamron is cutting even more corners, so the optical performance of the lens is not going to be absolute top notch, which means your going to have some optical aberrations on top of the diffraction, too (i.e. it's best performing aperture, it's actual DLA, is likely going to be a stop beyond maximum, f/9.)

So, I wouldn't be quite so certain that a top notch L-series 100-400mm replacement that uses the latest Canon optical tech like antireflection nanocoating on internal elements, maybe a fluorite element or two, and Canon's new high grade manufacturing process couldn't hold it's own against a mid-range 150-600mm superzoom from Tamron. It is still certainly possible the Tamron at 600mm outperforms the Canon 100-400 at 400mm, and it might even be able to edge out a 100-400 II if/when it comes out...but I wouldn't suspect the margin to be more than very slim...not with a 150-600mm zoom lens...too many necessary compromises.

There's no way the Tamron would be that bad. If it were, nobody would buy it, and I doubt Tamron would build it. This isn't the 1990's anymore. And from what I've seen, the Tamron 70-200 f/2.8 definitely is sharper than the difference in the price, compared to the Canon 70-200 f/2.8. 75% as sharp? More like 90%. 90% of the sharpness for 75% (or less) of the price.

What are you basing those numbers on? Gut feeling? It would be nice to have some actual numbers or comparable MTF charts to back up those claims... I know the Tamron 70-200/2.8 is a good lens, but saying there is only a 10% margin in difference between a $1400 off-brand lens and a $2200 brand-optimized lens just needs more than a gut feeling for basis.

You're just full of conjecture today, aren't you? Nothing you've said disputes anything I've said, it's just your opinion, period. Talk about gut feelings!
But I can state with absolute certainty that a 70-200F4 will out resolve a Sigma 120-400. That's a case of a zoom lens half as long picking out more detail, so I can certainly see a lens 2/3 as long doing the same.....

Granted, the new tamron will most definitely be sharper than a Sigma 120-400, but so will a new 100-400.... My gut feeling is that they will be close in resolving power, but who knows..... Either one could surprise us.... I would not want to make a prediction one way or another....

The rumored 400F5.6 is a different story..... It is already significantly sharper than the 100-400, particularly in the corners, and if it takes the same quality jump that any of the other long lenses took going from series 1 to series 2, it should have no problems outresolving the canon 100-400 II or the Tamron 150-600.

Beautiful shots Richard!

The first and third have an impressive light and detail in the foreground. Did you use any filters? Reason I am asking is that I will on the new year start off with the Lee system.
Sorry, took me a while to get back. Yes I did use filters, a combination of a Lee CPL and soft grads on the first two (the mountains prevented me using the Singh-Ray Revers Grad), it was a challenge with the mountains though and a blend would proably have been easier, but the challenge was too much of a temptation. The other was taken a few years ago, using the Cokin P system; that was a combination of the Singh-Ray LB Warming Polarizer and the 3 stop Singh-Ray Reverse Grad. I also used a touch of HDR on the third, just to recover the detail in the reflection.
