Lenses / Re: 70-200 F/4 IS repair cost
« on: September 17, 2012, 02:44:16 AM »
What was the warranty period?
Was it the maufacturers / dealers 1 year warranty or an extended warranty?

Is there evidence of dropping or physical abuse to lens?
[...]
Even if you don't or didn't, it doesn't sound to me like the lens has lasted a reasonable period given purchase price and specification.  In the EU you have additional consumer rights beyond the warranty, few folk are aggressive enough to pursue them, but they are there if you google.
[...]
EU default 2 year warranty. Dealer has to provide the 2 years. I first contacted the dealer 2 years and 3 weeks after buying date >:(

The lens is without any external damage. The only thing dented is the figure of speech that these L-lenses are solid as a tank ;)

I'll look into the 'reasonable period' a bit more. Maybe I can get at least a discount out of it.

Doesn't help you now, but, this is why you should carry insurance on your gear. If my 70-200 has the same thing happen, the insurance company hands me a check for $1000 and I get a new one.
I wonder if insurances would not put this off as 'normal wear', which is usually excluded.

Sometimes you can come out ahead by selling it as-is on ebay to someone who needs it for parts, or can fix it for a few dollars.  Those expensive parts are not really all that expensive if you put in used ones.
Another good option. But I doubt I could sell it for 500 euro or more in this state :)

The list of things to do says:
FOCUS ASS'Y, USM
LENS ASS'Y, 3&4 GUIDE BARREL
COLLAR DECENTERIG REPLACE

And the written description was "need to replace an expensive part and takes a lot of time".

Taking a lens apart is doable, but keeping it dust-free when putting it back together (if you don't need replacement parts) is not so easy at home. So the options would be to have a lens for 600 euro, or have a toy/paperweight and a new lens with guarantee for 1000 euro...

Lenses / 70-200 F/4 IS repair cost
« on: September 16, 2012, 02:40:40 PM »
Ouch! The focus system of my 70-200 F/4 IS was slipping (both in manual and auto), so I sent it in for repair: "600 euro to fix it". I'm almost doubting to get a new lens instead :-\

Just looking for moral support (guarantee period just ended a month before of course :(), and wondering if anybody else had this kind of repair.

Longer description: if I point the camera upward, it won't focus from distant to near, the focus group just slips. If I hold the camera pointing downwards everything works fine. Normal horizontal position will work sometimes.

EOS Bodies / Re: Any idea on how this was done...
« on: March 17, 2012, 04:12:23 PM »
I like the left-handed body in the 3rd pic :D

Given these shots it might have not been mounted at all, but just positioned in a way it seems attached for the picture.

The dog series is cute :)

22MP is fine, but at $3500 I'd hoped for some of these extra's (in no particular order):
- 1080p60 movie mode
- radio flash transmitter built in
- wifi built in
- articulated screen
- timelapse mode
- autofocus tracking in movie mode with 100k metering sensor

Even though photo quality should be great, in order to keep selling this cam for the next 3-4 years it would be nice to tick some boxes in the shoppers' wishlists that will match specs of cams to come :)

EOS Bodies / Re: 5D Mark III Full Spec List?

4. HD Movie. From what i understand the 22 MP count was to help in the video mode. I am not sure how that helps because 1080P at 16:9 is 2.073 MP. For a strict 4:1 super scale, you need 8.29 MP. So not sure how a 22 MP is better for video than a 18MP sensor. There is no sensor photo site scaling and so in terms of resolution etc, both will be the same.
[...]
3*3 sampling would get you to 22MP. The math:
1920*1080 video, but the sensor is 3:2, not 16:9, so you would need 1920*1280 (1920/3*2=1280)
1920*3*1280*3=22.12Mpixels

Lighting / Re: Do I need the 580?
« on: February 22, 2012, 01:12:23 PM »
I own the 430exII and love it for the pictures (mostly bouncing a ceiling).
Though next time I'd rather buy something else, because:
- doesn't rotate more than 90 degrees to the right, so you have to rotate left and flip
- changing settings takes too much time (slow buttons)
- no battery indicator

EOS Bodies / Re: 5D X or Mark III Specs & Release Date? [CR1]
« on: February 02, 2012, 10:25:24 AM »
And speaking of frame rate, the 1Dx uses 2 Digic 5+ processors. At 12 fps at 18MP= 216MP/sec. Scaling that to a 22 MP sensor, Dual Digic 5+ would be able to move 22MP at nearly 10fts.
One Digic 5+ would maybe do 5fts at 22MP??

So unless the 5d mk3/mkx has dual Digic 5+, I don't see how it can do 6.9fps.
On a single Digic 5+ CPU I can believe anything roughly under 5fps
Another hypothetical option to get the math working might be dual Digic5 instead of single/dual Digic5+.

Third Party Manufacturers / Re: Lightning-fast AF speed in a CYBER-SHOT??
« on: January 30, 2012, 04:21:04 PM »
This sounds a lot like phase-detection to us
It sounds like the system just takes a picture, measures the amount of blur, then starts zooming in one direction and takes another picture. Now it compares the blurriness of the two pictures and decides to continue focusing in that direction, or to focus in the other direction without hitting the front or back focus stop.
Comparing the blur on images can also give you an idea about how much further you have to go to focus, so you could speed the focus motor up and in the meantime keep adjusting your target by taking new pictures to compare.
Sounds mostly like a faster processor to do more math so focusing can be done faster.

Canon General / Re: Never delete images 'in camera'
« on: January 22, 2012, 04:11:10 PM »
There is no difference in the deleting process of your pc or your camera (unless you shoot raw+jpg and only delete one on your pc ;)). When deleting on camera there is a higher chance that you will use the disk space for a new picture again, if you continue shooting before trying to undelete.

Next to the before mentioned "you can only see what you want to keep on a big screen", another reason why I always keep my pictures is to make sure my numbered archive is complete and I know I didn't lose a picture somewhere.

« on: November 29, 2011, 06:33:31 PM »
Too bad they didn't specify the "HD SLR" they used for the side-by-side shots :) The difference in image stabilisation is huge. I wonder how the 7D/5D II video shooters feel about this comparison.

You say your funds are a problem, so I would suggest not taking the $650 course now.

Also, you don't have Lightroom yet. A free trial (win/mac) can be downloaded from adobe.com. You'd better first see if you like the program before spending so much money on it. For the greater part Lightroom works quite intuitively, but it is good to have some knowledge of the photographic basics of color, contrast, etc. to know which button to push to get the desired result.
If you feel you need to get more out of Lightroom than you can by just playing with it for a while, buy a book and do some self-studying. This allows you to use your own pictures, at your own speed.

If you still have questions after finishing the book, ask here on the forum :)

I'll have the finalists to show sometime this weekend. It's been more work than I thought it'd be.

Thanks for the update! I bet I wasn't the only one looking at this site just a bit more often than other days :)
