Hey guys,

thanks for your replies. I bought the camera about4 working days before going on a trip and decided to buy in store paying by card, so I wouldn't have to wait for the payment to clear and to give me enough time to inspect the camera over thoroughly. In hindsight I was probably being a bit impatient. In the end I went on the trip canon-less and Iphone-ful. Great!

I took the time at the store to inspect the camera and it was brand new, 0 shutter count etc. The seller wan't going anywhere and when it came to giving me a refund it was hassle free. But i agree, it's not worth the hassle when it comes to a fault.

My theory regarding the fake serial number, which I made up after some Sherlock Holmes style Internet research is that an official Canon distributor in Singapore or Hong Kong wants to make some extra cash, so they sell to the european market for lower prices than customary in Europe but higher than in their own market. As this is probably against Canon (and possibly local) trading regulations, they put fake serials on the cameras to try and hide the traces that would lead back to them. As I said, it's just my layman's theory.

cheers. mattia
Hi,
    Parallel import or grey market goods are not against any trading regulations (you just don't get local warranty), but I think faking serial number is. Just look at the warranty card and you'll know where is it from... unless they also fake the warranty card??

   Have a nice day.

Hi,
    I think it's should be weather sealed, but does "The structure is also sealed and gasketed to resist dust and moisture" mean it's weather sealed??

Hi,
IF RGB + IR does not refer to metering but the image sensor,
THEN this is the most interesting camera of the last 15 years.

I think I need one.
    Yes... very interesting if mean the imaging sensor... does it mean can took IR image without mod the camera?? If so... very interesting indeed....

   Have a nice day.

Count me as another that finds this to be a very interesting feature, if it is the image sensor.

Overall, this sounds like a potentially excellent camera.  But, we should wait and see if there is new technology especially sensor tech.  You can only tell so much by a spec list.
Hi,
    Look like it's the metering sensor...  :P
Hmm... just wonder why metering sensor need to detect IR?? Meter subject that give out heat??

   Have a nice day.

Hi,
I can't be the only one who uses a super tele (albeit slightly lighter than the 600) almost exclusively handheld? The idea you'd always have it on a tripod is a bit perplexing. For sport sure, I seen photos of the sidelines of football matches etc. But for wildlife... I find it rare that the things I want to photograph are static enough that I could set up and use a tripod  :-\

I've never used a tripod, even a monopod, with my 600 (version I) and I can't even understand how one can work that way… On the side line of a soccer/rugby game, maybe, but that's all. It ain't that heavy, and IS + ISOs these days make it easy for us to shoot handheld.
Twice a week, i work in the parliament, handheld, with the IS i can get down to 1/125 (but that's the definitive limit).

Well……if I may say so……when I watch the pictures shot by the people on this forum who tend to only work with a tripod……I think that they really should try to shoot handheld...
     Not sure how you guys management to handheld the 600mm f4 for an extended period of time...

     Anyway, I had seen more than 20 people using 600mm f4 and never seen one handheld it... not even the 500mm f4... all are use on a tripod.

    Have a nice day.

EOS-M / Re: Star trails (continuous shooting + long exposure)
« on: September 06, 2014, 08:56:19 AM »
Hi!

I have done some star trail shooting with my 1100D but now my friend wants to learn how to do it with EOS M. Last night we tried it but it seemed impossible. There wasn´t a chance to use continuous shooting + remote control + long exposure (30sec). Any advice for this one?

Here´s one software for the star trails: http://startrails.de/

Hi,
    Usually we use a timer remote controller to do this... set to "M", bulk mode and Single Shot and use the timer remote controller to set the number of exposure we need, the exposure time for each exposure and use the startrails software to create the final star trails image by stacking them. The advantage of this method is you can get a nice star trails without getting too noisy especially good if your sky is not very dark. Disadvantage is you will see small gaps (many if your exposure for each shot is very short) in the star trails if you look at 100% corp or view on very big screen.

    Anyway, your EOS M don't have a remote controller port, so you had to do the manual way... use the remote controller to manually take each shot... a lot more work.

   Have a nice day.

Third Party Manufacturers / Re: SIGMA 150-600!!
« on: September 06, 2014, 03:04:32 AM »
Sigma is into flourite now? Very interesting.

No, its FLD glass - fluorite equivalent. Its what they use in the 120-300 2.8 Sport, 50 1.4 Art, etc.

I'm curious about what they mean by teleconverter compatibility.  Another part of this announcement is the new 1.4x and 2x tc's. Sigma says that this new lens is optimized for them. There is no way the 2x will AF on any body of course, but I wonder if the 1.4 might with f8 focusing bodies. The large 105mm filter size suggests that it may be a "big" 6.3, possibly to enlarge the image circle for better corner sharpness but it could also allow just that bit more light necessary to get reliable f8-ish AF. Or it could be marketing and the TC's are manual focus only. I wonder though because Sigma said specifically that tele's do not work on my 300-800 5.6 zoom and they seem to suggest otherwise with this press release.

Also, this forum is weird. I posted a thread about this in a different sub forum this morning but instead of locking the thread and pointing to this one, they renamed this thread with my title and moved my original post into this thread where it doesn't make sense. That seems like a weird and confusing way of doing things. And there are waaaaay too many sub forums with overlapping topics. Half of them could be merged or deleted and nobody would miss them.
Hi,
   Sigma had been using FLD lens since 2010, so nothing new...
Anyway, about the TC, 1.4x possible, but 2x?? Who's know... may be Sigma got "inside news" that may be the new generation of DSLR will allow AF at F8, F9 and even F11... :P

   Have a nice day.

EOS Bodies / Re: Are you planning to purchase a 7D2
« on: September 05, 2014, 11:21:26 AM »
Hi,
Hi,
    I use my DSLR mainly for birding and now using 6D with Tamron 150-600mm. I feel the center point AI Servo AF of 6D is slow, but I'm not sure whether is it the 6D center point AF is slow. If 7D2 AI Servo AF is faster, more accurate and more reliable, most likely I'll sell my 6D and get a 7D2 (unless the 7D2 is as expensive as a 5D3).

   Have a nice day.


Have you tried the firmware update on the Tammy?  I've not, but I think that may resolve a lot of your problems.  I'll be sending mine in soon!

I have used the 5dmkiii and the 70d on the 150-600.  Results on the 70d are rather disappointing.  Part of the issue is that it just looks like crapola once you go above ISO 1600.  Anything higher than that, I'm much better off going to my 5d and cropping.   

So the 70d has prettymuch collected dust as I bought it for birding, but I need greater than 300-400mm still, so it wasn't exactly the perfect combo with the Tammy I thought it would be.  It does look great on the 70-300L however, but I still don't have the reach I want.

I'll only buy the 7dmkii if there is a substantial increase in quality (iso3200 useable images).    Otherwise, I may just ditch the crop frame all together, and bite the bullet on a used 500F4 and use on the 5dmkiii.
 
    Not yet, but is there a new firmware??

   Compare 6D with my 60D center point AF, the 60D center point AF is more accurate on small subject... I think may be because the subject is bigger in the 60D AF sensor.  Also, base on my observation, if I scale down the 60D image by 1.6x, the 60D IQ is around the same as the 6D IQ up to ISO 3200, 6D IQ is still better than the 60D scale down image when ISO is above 6400. So if 7D2 AF is much better, I'll consider the switch... basically trade IQ with better AF.

   Anyway, will try out various settings and ways to improve my focus accuracy... if can overcome the problem, I'll keep my 6D as I like it very much especially with the 40mm pancake on it.

   Have a nice day.

Hi,
    The front element is nearly the size of a 300mm f2.8, but why only f6.3 at 600mm? Or the front element is just a protective element??

    Anyway, the only feature I like about this lens is that it can lock at any focal length which to me is very useful (if I want to use it for Astrophotography), but I already have a Tamron and not 100% convince about the QC of Sigma yet.

    Have a nice day.

Hi,
.
Doesn't Sony introduce a new camera every day?
18 e-mount cameras since 2010 (not counting video cameras)....23 e-mount lenses (of which at least 2 were refreshes of existing ones).

Imagine how much better off they'd be if they had just made the NEX5 or NEX7 and build a lens system around it.
    WOW... so many?? They thought they are selling TV??

Anyway, if I buying an electronics product that's I need it to last, it'll not be a Sony product... their support is very bad especially if it's an old model.
 
    Have a nice day.

Technical Support / Re: star trails etc- - infinite focus
« on: September 01, 2014, 08:19:51 AM »
Hi,
   I think the infinity focus will change a bit when temperature change, so the scale is not very accurate. Also, with such small scale in modern AF lens, it very easy to misfocus a star... a bit off and the stars is blur... use live view will be easier.

   Anyway, to focus a stars to tack sharp is very challenging, so challenging that there are even software for it... ha ha ha  :P

   Have a nice day.

EOS Bodies / Re: Is Canon now two generations behind Nikon?
« on: September 01, 2014, 02:50:23 AM »
Hi,
The REAL QUESTION is how many generation is Canon behind Sony, Olympus and Panasonic ???

The photographic world is rapidly changing. Now Video is a BFD with many photographers (and has been for several years). And ALL professional video cameras use EVFs. Even Canon has EVFs on the C100, C300 and C500. So why no EVF on the 7D2 ???

You may want to view this video The Mirrorless Revolution and learn why Michael Reichman has sold all his DSLRs  http://luminous-landscape.com/whatsnew/#1129
   Err... I thought all video cameras are mirrorless not just professional ones... didn't see any consumer video camera come with a mirror... ha ha ha :P

   Anyway, 7D2 is supposed to be a sport/wildlife DSLR which IMHO, is not suitable to use a mirrorless design basically due to the power consumption. Not sure about sport photographer, but wildlife photographer use the viewfinder a lot even not shooting as the super telephoto lens can be use as a scope to search for your subjects. If it use an EVF, power will use up very fast and sensor will become very hot after long use... image quality will not be good when sensor become hot.

   Have a nice day.

Hi,
More often there is a thread specifically about sensors or DR or banding and the same set of Canon defenders always comes in and jumps all over

Sorry, but no.  More often it's a thread about anything but DR and one of the DRones comes in and makes it about DR, and others chime in to counter that.  Mikael/ankorwatt hijacked countless threads.  Earlier today jakeymate posted his diet coke box noise images (from this thread) in a thread started by someone wondering about changing the color profile of their Canon on-board LCD.  Nothing to do with sensors or DR, at all...until Dean the DRone showed up, that is.  ::)
    +1

     Recently, when I read a thread not about the DR, I always had the feeling that the thread will end up about DR.... ha ha ha  :P

    Have a nice day.

Would someone explain to me what is wrong with pointing out the weaknesses of your brand and hoping that future models improve on those weaknesses?

Not a damned thing.

+1

Honestly and fairly pointing out weaknesses is something consumers should do, assuming their products matter to them. 

Many people, myself included, discussed the lack of a sharp-to-the-corners UWA from Canon.  Now, we have the 16-35/4L IS. 

I bitched loud and long about the 5DII's AF system, which was pretty similar to that in the 20D...which was the same system used in the entry level xxxD bodies at the time.  Now, we have 1-series AF in the 5DIII.

For those two examples, a sizable portion of Canon's customer base felt there was an issue to be addressed.  I think the difference in this case is that there is only a very small minority complaining about Canon's lesser low ISO DR.  The other difference is the way in which some members of that small minority seem to exaggerate the issue out of all reasonable proportion.

Hi,
   Why don't they just add the shipping of compact camera, video camera, security camera, webcam, camera phone and etc to the mirrorless shipping figure (technical speaking they all are mirrorless as they don't have a mirror in them), then the mirrorless figure sure will overwhelm DSLR figure...  ;D

    Anyway, I believe one day all camera will be mirrorless, but that day is not today, tomorrow or next year... may be 10 years later... also, the mirrorless camera will be just as big and bulky as current DSLR because to get good image quality, you need large lens and large lens doesn't go well with small camera... and to have good ergonomics, the camera cannot be small due to the size of our hands (I don't think our hands will be smaller in the near future...) and of course you need space for a large battery as mirrorless "eat" a lots of power.

   Have a nice day.
