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..

Canon General / Resurrection, of the posting kind.
« on: December 13, 2014, 06:15:58 AM »
Hi Folks.
Is it me or are we getting a whole lot of 1 or 2yr old posts about scams etc resurrected by 1st time posters recently?
I have been going to reply to a couple of them then checked the previous post because I thought I recognised the thread from my early days.
A lot of long serving members are then sucked in, adding to the momentum, can we get these older scam posts locked so they are there for reference only or would that be too difficult?
Just a thought, perhaps it is only me that it bothers?
Please understand I don't see resurrecting an interesting post as a sin, just the scam ones! ;D

Cheers, Graham.

Canon General / RTFM. Do you?
« on: December 10, 2014, 10:00:21 AM »
Hi Folks.
Just for giggles and to save hijacking someone else's post, do you RTFM, and what drove you to it?
I first resorted to RTFM as a child many years ago when I was trying to build a Technical Lego tractor from the picture on the front of the box! It hadn't gone too well, not as simple as it was to build the standard Lego cars and such just from the box image!
Technical Lego was new then, before it was called Lego Technics!
Since then I have tended to Read The Flamin' Manual first for most stuff.

Cheers, Graham.

Canon General / Please help me! 1DX Fever, (G.A.S.)
« on: November 30, 2014, 02:03:10 PM »
Hi Folks.

Please help me, I went to the LCE Southampton show and I did not follow the advice previously given on this forum, I picked up the 1DX, held it, tried it, and I now find I am in desperate need of the antidote for trying a 1DX! I fear that not being able to afford one is only part of the antidote!  :'( Damn that thing feels good with a big white on it.
Should have stopped after trying the 5DIII! ;D

Cheers, Graham.

Technical Support / Need help with 450D losing time and date please.
« on: November 22, 2014, 08:52:05 PM »
Hi Folks.
A friend has just bought a 450D kit, may not have been the bargain he thought!
Each time he removes the battery, the time and date are reset, I know this means that the backup battery is flat, the problem is that on the 450D the battery is a "built in secondary battery" p183 of the manual.
So far I have read that sitting discharged for a long time kills these rechargeable cells, seems most cameras out there come with the rider, "not been used for ages so thought I'd sell it"!
Will it only charge from a "full" battery? He has 3 batteries, one won't fit because it is swollen, one we freshly charged and on insertion only showed 1/3, or is it 1/4, the other only seems to charge to 1/2. He is reluctant to spend money on new batteries if this body is a dud. Anyone know if it is within the scope of DIY replacement to swap out these built in backup cells? If he has to try again he will probably go after a XXD. (My fault, I showed him how much easier setting changes are on a 40D!)
Hoping that between you folks you can enlighten us on these questions.

Thanks in advance.
Cheers, Graham.

Edit. Just a thought, I guess this would mean custom menu settings would be lost too? Or are they written to non volatile memory?

Canon General / Lucerne, where to go?
« on: October 30, 2014, 04:15:00 PM »
Hi Folks.
Going to be in Lucerne for a couple of days this weekend, anything recommended to see in the immediate locality? Needs to be within public transport range, not necessarily photo related. Short notice as it was a bit unexpected!

Any ideas appreciated.

Cheers, Graham.

Canon General / Lens identity?
« on: October 27, 2014, 08:47:00 PM »
Hi Folks.
I hope someone can identify this lens for me please, it is a ropey picture from a for sale add. Long story short, I don't want to seem too interested in it, asking too many questions might increase the price as it is on a camera with problems for sale make a sensible offer. Knowing what it is will help me decide on an offer price, or if I even want it.

Thanks for taking time.

Cheers, Graham.

Technical Support / Downside Up?
« on: September 27, 2014, 08:27:21 PM »
Hi Folks.
I was out today doing some landscape shots with the camera upside down, came home and put them on the computer, clunky old laptop, where they were displayed inverted.
My question is why were they not displayed up the right way, I have rotation set to computer only on my 7D, shot raw only. Does this setting only affect JPEGs, does it only work for 90 degree rotation, i.e. portrait and cannot recognise an inverted camera?
I checked the software, Fast Stone Image Viewer, which was set to rotate according to exif data.
Is there a way to rotate the raw file, or is this not a good idea due to having to overwrite the original? Is there a way to get it to display upside up!

Thanks for your help.

Cheers, Graham.

Canon General / How do you cull your photo's?
« on: September 07, 2014, 05:05:58 PM »
Hi Folks.
I went to the Bournemouth Air Festival last weekend, so many excellent planes, though the sad thing was that the Canadian Lancaster was not able to fly due to an engine failure, really wanted to see two Lancs together.  :'(
The problem is I now have 3 thousand pictures over the two days, I was wondering if any of you have any tips on how to cull the shots?
Saturday was rather dull and overcast, I was going to ditch most of the pictures taken Saturday but I already found a couple that look like I was flying above the display plane looking down on it flying above the clouds!
I'm already going through and ditching any that are OOF or have bits cropped off accidentally, but how do you distinguish between 2 similar shots, so far I have used whether the prop blades are obscured or other similar things, any tips? Flicking back and forth between the raws in windows viewer is taking ages, and this is the first time I shot raw only!
I don't want to try to open thousands of images in DxO, I think it will crash may PC! :o ;D

Also how do you get the props or rotor blades to blur without blurring the whole thing, I dropped the shutter speed progressively until I had blade blur but got about 5 keepers from dozens of shots, speed was well below 1/focal length less four stops for the IS, I guess it is down to panning technique more than anything else?

Cheers, Graham.

Canon General / Those D'oh moments!
« on: September 07, 2014, 04:16:49 PM »
Hi Folks.
Well I went to the Bournemouth Air Festival last weekend, what a great event! Thanks to those who guided me on camera body lens combinations to take.
Saturday I got the kit sorted and started walking away from the car, she says have you got spare batteries and cards, D'oh pick up spare cards, I was relying on gripped bodies to only need the batteries on board for the days shooting! They made it with loads in reserve.
Sunday I'm in a nice little spot part way up the cliff shooting merrily away and get the CF FULL message, reach to my pocket, D'oh no spares much muttering and cursing and another photographer with Nikon gear noticed my distress and offered to lend me a card, thanks Kim, but I decided that the best way was to punish myself with a forced march back to the car for my own cards.
I discovered after the first ten to fifteen minutes of both days that I had left the ISO cranked up from the night before, D'oh, not critical but it does hurt image quality a bit when you don't need the high ISO.
Seems about the only thing I got right was the carrying system, a Black Rapid Double fixed to the tripod feet, and OpTech 3/8 webbing on the body lugs with an OpTech utility loop on the belt loop of my trousers for security during the walk in and back.
On the forced march back to the car I had that heart in the mouth moment when the shoulder strap went light by about the weight of the body, and I heard things rattle on the ground! Phew the body was swinging on the strap in front of my leg, I know exactly what happened, the phone in my pocket knocked the lens release and the walking action twisted the body off the lens. The rattle on the ground was the hot shoe cover had fallen out!
I had read the posts about bodies dropping off lenses sometimes with catastrophic results and thought that it may have been a freak occurrence, I can tell you it happens easier than you might think, it fell off on the way back to the show too.

Let's just say I know why I will never be a professional!  ;D

Cheers, Graham.

Software & Accessories / Jpeg image sizes?
« on: August 25, 2014, 02:08:44 PM »
Hi Folks.
I was just spending some time getting to grips with DxO. I exported some images to file as Jpegs, they were in the order of 20Mb. I thought I could get away with half size for what I wanted as I have no intention of discarding the raw file!
I see a scale in DxO export settings, Quality 0-100, must be percent right? That is the first assumption that will prove a point! ;D
It obviously isn't percentage, but what is it, from trial and error I find that somewhere in the 96-97 range gives half size files! Please see attached list.

Dxo jpeg sizes by Valvebounce25, on Flickr

The blue highlighted set is from one image, I realised it was a crop when I went to compare the raw file so I repeated the 95-100 set and added the raw for comparison. Can anyone tell me how this scale works, it just seems completely random that a quality of 50/100ths (%? ;D) can give a file size of 1/16th the full size file.
Someone must know the answer to this, please! It's making my brain ache!  (How do you draw a smiley with smoke coming out the ears?) ;D
Thanks in advance for help with this, I know it is not necessary to know the answer but enquiring minds need (like) to know.

Cheers, Graham.

EOS Bodies - For Stills / Lens to body pairing
« on: August 19, 2014, 09:53:17 AM »
Hi Folks.
I am going to the Bournemouth air festival, for those that don't know it is a free display with the aircraft flying over the coast, no access to parked aircraft as far as I am aware.
I would like to know the thoughts of those wiser than myself on which lens to put with which body for best image quality?
My thoughts are:-

Bodies                    lenses
7D        With      EF 70-200 f2.8 IS II with or without EF 2X III depending on how close or far the planes are. 
40D      With      Sigma 150-500 f5-6.3 DG OS HSM

Please could I have your thoughts on whether this is right or wrong!
Is it worth having the extra camera just for the extra 100mm?
I am looking to get a Black Rapid Double for carrying both, as it converts neatly to a single too when I only want to carry one body. Thoughts on that?
Anyone been and able to tell me if I will need the 2X III on the 70-200 or not?
Thanks in advance for your input.

Cheers Graham.

Software & Accessories / Benbo Tripod?
« on: July 29, 2014, 08:30:07 PM »
Hi Folks.
Anyone used a Benbo Tripod, there is one for sale locally that might be toooo cheap to pass up if they are any good! In fact there are two now at pretty good prices if they are good!
Thanks for any feedback, btw that is Benbo (apparently stands for bent bolt) not Benro which I saw was not too good from recent posts.

Cheers Graham.

Software & Accessories / DxO upgrade question.
« on: July 24, 2014, 04:31:29 PM »
Hi Folks.
I have decided to get DxO, I have found version 9.0 genuine licensed boxed product on disc cheaper than the version 9.5 download before the special offer finished.
I would like to know if upgrading from 9.0 to 9.5 is one of the free minor upgrades, if I have to pay it is possibly not worth doing.
Anyone using DxO know the answer please?

Cheers Graham.

Canon General / Exif data, does it help, do you need it shown?
« on: July 23, 2014, 07:59:43 PM »
Hi Folks.
I often view images on the forum, almost exclusively on a tablet, some images are hosted on Flickr or similar, so I can see the exif if I click through, others don't have this facility, and I can't view the exif with a right click like I could on a PC.
I know I'm not the only one who asks for camera settings and gear configuration for the shots to be added, I'm just trying to find out why.
Multiple votes are allowed, there are 6 votes allowed for ten questions. For instance I sometimes use my Android tablet but mostly iPad so both are relevant.
Please feel free to add any thoughts in a reply.

Cheers Graham
