Technical Support / Question about 50D known issues or recalls.
« on: December 17, 2014, 08:25:29 PM »
Hi Folks.
A friend of mind has just picked up a 50D, it has a short warranty and about 8500 shutter actuations, any known issues with this body, recalls etc. He would like to know what to look for before the warranty runs out.
On the subject of recalls, do Canon cover older models, out of production and warranty, will they cover a recall on second hand gear or only for the original owner? 

Cheers, Graham..

EOS Bodies - For Stills / Re: Vertical curtain velocity
« on: December 17, 2014, 08:13:41 PM »
Hi Milan.
To answer your first question, it looks like you understand the operation, yes the width of the slot is the equivalent of the shutter exposing the whole sensor for e.g. 1/8000th of a second. As Neuro has explained the longest fully open I'll leave it there. As for how fast, others already gave the numbers for that.

Cheers, Graham.

I was thinkig about real velocity of shutter curtain. I guess that vertial curtain velocity does not change and changes just timing of second curtain release. It means that slot between curtains travels at constant speed, but width of slot depends on shutter speed set up. The amount of light reaching the sensor is the same as shutter would have been fully opened for a very short time, e. g. 1/8000 s. Are my thoughts correct? If yes, how fast the curtain could travel?

Hi Neuro.
Thanks for clearing that up, I had a quick google about restricted tech, never really thought of in camera GPS as high tech military equipment! 

Cheers, Graham.

If there's a (G) version, there's also an (N) version for sale in markets where GPS is prohibited.

Hi dolina.
I have several DSLR to choose from, I have a 20D 17-85mm Nissin flash combo that is almost always with me, it gets bounced around in my van and car and used to document work. The other day I had a days impromptu photo walkabout. I took my van in for new tyres at 10:30 and the electric supply got cut with my van raised on the lift, what you going to do? I grabbed the camera and went on a walk along the disused railway line, up to the river, out for lunch, finally got my van back at 17:30!
Got some niceish pics that I wouldn't have got with a phone. Got to PP them then post a couple to the site.
I do not like using a phone, don't seem to get on with holding at arms length, and you don't half feel silly when you put it up to your eye! ::) :-[

Cheers, Graham.

Technical Support / Re: 5Dmk3 grip rubber coming loose
« on: December 16, 2014, 07:59:33 PM »
Hi Folks.
I had this problem with my 7D, the rubber under the shutter button became detached. I cut a strip of double sided tape about 1/16 to 3/32 inch wide (1.6 to 2.3) mm wide, similar to the original tape, roll down the rubber a bit, pick out the old tape, place new tape with the end of a cocktail stick and carefully fold the rubber back up. I found that after rolling the rubber down it was slightly stretched, requiring careful alignment to prevent the tape from being under tension if or when the rubber returned to shape. Essentially you are trying to remove the bagginess as you go.
I think if it hadn't been for me checking if the edge was stuck down it would have lasted a lot longer! ;D It was fixed for months, but I kept worrying at the edge with my shutter finger until it was loose again! ::)

Cheers, Graham.

EOS Bodies - For Stills / Re: Canon EOS 6D Firmware 1.1.6 Released
« on: December 16, 2014, 09:50:56 AM »
Hi wsheldon.
It would seem you already know how to backup your AFMA data! ;D
I think FoCal might do it if you use FoCal. It will back up the settings at the beginning of a test and restore afterwards, if accidentally disconnected (think battery goes flat) it will ask if you wish to restore next time it detects that camera is connected. Whether this would work across a firmware upgrade I don't know.
Why not just re familiarise yourself with all the lenses you own and see how lucky you are to have so many lenses that it will take so long to do!  ;D ;D Don't forget the extender combinations too.

Cheers, Graham.

Is there a way to back up and restore AF micro-adjust settings? I'm tempted to apply this update for the rare occasions I try AF tracking, but don't want to have to re-do all my AFMA settings, which are by-lens right now (I'm on 1.1.3). Of course I could mount all my lenses and write down the settings, but I'm lazy :)

Hi Folks.
My 7D works at least as well as the day I bought it, if not better, if it is better than when I got it it is because of you good people here helping me to understand how to get more from it. I have G.A.S. but I have a limited (very) budget, so I disperse to my family my wish list for Christmas and hope some of the G.A.S. is dealt with that way! Every small add on costing a few quid is a few quid I can save and buy the bigger things with, also it is one (or more) less chocolate bar to regret eating later! ;D
It is easy to think that the marketers are right, but nothing changed on my 7D the day they released the mark II, the only difference was that the bar got raised slightly.

Cheers, Graham.

Hi Neuro.
Does this mean they do a 7DII without the GPS, or just tough, if you live in that region you can't have a 7DII?

Cheers, Graham.

G = GPS.  The 6D is WG (wifi + GPS).  Models with wireless/GPS features can't be sold in some places.

Hi JPAZ.
I'm with you on the automated filters, I guess I was thinking it would be a mod do it. I hate automated filters, I was trying to look at a warbird site on my phone when I was thirty something, my phone provider had some filter in place that kept stopping me. The warbirds had nose art some of which featured scantily clad ladies!!!

Definitely don't automate a filter.

Cheers, Graham.

My place of employment is very adamant about protecting them (and us) as well as bandwidth and use some sort of software to prevent us accessing certain websites or receiving certain emails.  Like any automated system, it is very flawed.  I've been blocked from very legitimate sites including airlines (to book business travel), my personal email account, partner/client sites and even our own payroll department when trying to  get a copy of a paystub.  Meanwhile, I still get plenty of "click-here-to-get-rich" and requests for help from a "grandchild-in-jail-in-a-foreign-country" (always humorous because my oldest grandchild is under the age of 2) but can often stream reviews like DigitalRev (not that this is a bad or dangerous internet site unless you suffer from G.A.S. but it does use significant bandwidth to stream) and our system does allow me to open CR and CPW (again a good thing but makes no sense given the IT department's goal). 

My point is that automated screening or protection algorithms are very flawed and could lock legitimate posts unnecessarily.  And, the "bad guys" are getting smarter and can often overcome these.  So this leaves the weary mods to act both on their own and with the help of reports from the forum members. 

I guess I'd rather deal with some trolls and misleading threads than have an automated system delete one of my posts just because of a word in the message.

Hi Dylan.
That monitor looks real nice. I think I will have a lot to learn, no idea about gammas or anything else. It is enlightening that you have such an improvement in your images.

Cheers, Graham.

Hi Dylan.
I have a Color Munki Display on my Christmas wish list, hopefully this will help with my photos.

Cheers, Graham.

I heard positive things about Color Munki

I bought this LG: http://www.lg.com/us/commercial/lcd-computer-monitors/lg-27MB85Z-B

It came with calibration hardware + software. It also has 3 pre-calibrated presets from manufacture - Gamma 2, 2.2 and 2.4. I'm current using Gamma2.2 preset. I only adjust the brightness and reduce to 50 seem to be a magic number for me.

Technical Support / Re: How to remove a filter that is bent.
« on: December 14, 2014, 04:39:53 PM »
Hells bells, the guy in this video is AN ANIMAL. If you follow this you might as well send it straight to Canon as I would bet the strain on the workings would do damage. The idea is not to try to tear it off the front but to twist a V in to the circumference (across the front) to reduce the diameter, therefore reducing the tension on the thread. Whilst doing this if you hold by the filter, the stress, or force will not be transmitted to the lens.

Cheers, Graham.

If you are brave enough, try this one

Hi lintoni.

D'oh

In my head it went locking old threads, but you don't read thoughts right?  ::)
Good point about vindictive people. It's sad but they are about.  :'(

Cheers, Graham.

Hi Admin 
I was wondering about a search for the word scam as it seems most of these posts have been identified as scams by at least one response, then lock that thread. I would sooner put up with the resurrected posts than have all threads locked, some fantastic threads have been resurrected, on a seasonal basis?

Thanks for what you guys do, I think the level of moderation of this forum is generally very good.

Cheers, Graham.
You've just got your thread locked!  :D

You wouldn't be able to talk about scams in a legit thread.
Somebody who was feeling vindictive could post the word scam in threads and quickly lock up a substantial portion of the forum.

Software & Accessories / Re: HDR vs ML Dual ISO
« on: December 13, 2014, 11:35:32 AM »
Hi meywd.
I have to say the second shot is to me acceptable, but only you (and anyone else there at the time) know the true colours I should be seeing. Of course having seen the HDR version, and assuming that the colours of that are what you actually saw then I can see that both techniques are a significant improvement on the single shots.
I apologise if I gave the impression I was being critical, it was not my intention, I have no idea how to create the HDR image save for showing a bit of software the 3 images and letting it go to work in full auto mode.

Cheers, Graham.
