Technical Support / Re: 5D MARK III - does not read CF card
« on: July 30, 2012, 05:02:58 PM »
Get some good light and look into the card slot at the pins.  A magnifying glass might help.
Look for pins that are bent over.  They symptoms are of a bent pin.  Bent pins in the camera body are a serious issue with CF cards, it doesn't happen too often, but when it does, it can be expensive.  I've had a 50% success in fixing them, and my job involved engineering and testing things like this in a lab. 
Being a high reliability company, we would not even consider putting a product on the market with pins in the power side of the interface.  Power gets bent and touches ground or other circuit element, and the whole camera is slagged.  If not, its just a few hundred to replace the card socket.
A really really poor design, but its worked its way into being a standard for many years now.
Thats why many cameras use SD cards.  They might not be as fast, but if they fail, you toss a cheap card rather than the camera.

Over a extended period, lubes may either harden, or separate and run into places where they do not belong, plastics out gas and get brittle.  This would happen slowly over a period of many weeks or months.
In the short term, the battery might vent and sustain some minor damage.
I really doubt that 2 days might damage it, but it is definitely a risk if done regularly.

Prices do change over time based on market conditions.  In the case of a poor world economy, or a problem with the camera that scares buyers away..



Once you've had time to get any bugs figured out, I'd ask Canon about the under exposure.  Canon can adjust it.  Generally, all my 1 series cameras have had more accurate exposure than the 5D series.  However, I've always noticed a slight difference in accuracy when comparing indoor versus outdoor exposure accuracy.

You can substitute the yellow for another color in photoshop, but I'd just take another photo with indirect light.  Its only worth the effort to photoshop something like this when you have a photo that cannot be redone.

You might also consider a used 1D MK IV, its very good at video and sports both, and can be had in the 3600-4000 range.
The 7D has fast AF, but as light gets low, the need for fast shutter speeds means cranking up the ISO.  In low light, ISO 3200 can be pretty noisy, but 1600 is ok.
You can use a 1D MK IV at ISO 12800 with NR.

A local Photographer had a Nikon 200-400mm AI-S for sale.  He had only used it twice, and it sat in its Nikon pouch looking like new for 30 years.
When I tried to focus it, the focus ring was so stiff that there was no way it was usable.  The aperture was likely in the same shape.
If the lens had been used regularly, its likely that it would have been in better condition. 
I asked a local repair shop about it, and they said its a common problem, the lube hardens and has to be scraped out and replaced.

Plastics outgas and get brittle, lubes harden, but if its in good shape and maintained, its likely OK.  Still, I will not buy a older lens unless the price is significantly discounted.  Its merely playing the odds, given two lenses in similar condition, the older one is more likely to need repair.

Nine percent  seems pretty high, I just sold a $1700 lens and it cost me 2.8% plus the 3% PayPal fee.  I sold it for a much higher price than I could have on Craigslist, so I came out well ahead.

Out of curiosity, how did you manage that? It looks like the auction-style Final Value Fees are 9%. I have read through everything and can't seem to find a lower fee structure.

For 3% I would definitely list it. I just don't see that option available to me.

Any pointers would be appreciated.

I list my stuff as fixed price listings.  Its far cheaper.  I also get a 20% discount for being a high rated seller.  Trying to list it as a auction jumps the fee to 9%. 
Without my 20% discount, the final value fee for a fixed price sale of 2,000 is $71.52 or 3.57%.  Put in my discount, and the fee is $57.32 or 2.866%.
Just do the research and set your price according to what selling prices actually are.  If you do not have a lot of ebay feedback, consider asking someone who does to list it for you, with no feedback, its hard to get a good price.

Third Party Manufacturers / Re: Question for Kirk L-Plate users
« on: July 28, 2012, 10:08:28 PM »
I use Kirk Clamps and they have worked well with the various plates.  I bought a few when Kirk was selling them for $20 on ebay, but the price has jumped up.

EOS Bodies / Re: 5dIII hot pixel question
« on: July 28, 2012, 09:59:09 PM »
I did not find any hot pixels on my 5D MK III, in fact it was amazingly devoid of them.  But then, I did not try to create them with a super long exposure.
If you actually need 30 sec exposures at ISO 800, take a dark frame and subtract it.  Thats pretty much the standard for long exposures.

Thanks for the help! Think going with the t3i. I found a scratch protector for it too. Same place I got one for my phone, www.xoskins.com... I'd recommend them for anyone.  :)

Canon DSLR's have a replacable protective cover over the LCD.  If it gets scratched, you can order a replacement from Canon.  It is held in place with a die-cut piece of double back tape.

Big gap between 50mm and 135mm.  Consider a 85mm or 100mm lens, or get a walk-around zoom like the 24-105mm L.

Lenses / Re: Lenses - All Change!

I'd think the 135mm l would be a little long on a 7D, but it depends on your style.
The 85mm f/1.8 is very good and reliable, but it is possible to have a damaged or malfunctioning lens.
As far as CA, its now pretty much a non issue, Lightroom 4 will even remove or minimize LoCa's as well as make other lens corrections.
I'd first get your lens checked out.
