Yep, fully aware of that, but it's beside the point: I'm letting people know that despite suggestions to the contrary, both the 7D and the 70D will work in circumstances which some on here have stated they won't work in.

If you use a non reporting TC, even a old 10D will autofocus at f/8 with some lenses.  Others do not work.  I've tried in numerous bodies and lens combinations over the years.  The TC you use also makes a huge difference, some work better than others.

They do not track a subject fast enough for bif, but for a still object in bright light, they work fine.  My 5D MK III worked much the same way before the firmware update.  It is now more stable with F/8 AF then it was with taped contacts or non reporting TC. With some lenses, it just rapidly vibrated the focus at F/8.

Technical Support / Re: Anyone Repair your own DSLR Bodies?

This is the first DSLR repair I've tried other than replacing the LCD covers (they cannot be replaced on newer bodies any longer).

I'll buy parts from Canon, a distributor, or even ebay depending on who has it in stock.  The cheap $5 LCD cover came from China, it may be a fake, but it looks and fits good.  A fake piece of clear plastic isn't a concern to me, a fake battery is!

I did not take photos, I only spent a hour for the whole disassemble / reassemble process, including the replacement lcd cover.  I was in a hurry to get it over with, my PC dies and I needed to put the remains back together today.  I narrowed it down to a processor or motherboard issue, its not worth it to replace them, its a old i7 first generation processor.  I'll probably get a new processor / motherboard / memory when Haswell E comes out.  I might spring for updated video as well.  In the meantime, I have a New Dell XPS 8700 arriving tomorrow, along with a SSD and hard drive.  I'll remove the hard drive with windows 8.1 and put in the Samsung MSATA SSD and a 3TB Hard drive and install Windows 7 64 bit.  Then, a 2nd DVD Burner.  I'll rotate the oldest one (i7 2nd gen) to my workshop and use the newer one in my office.  I usually upgrade every 2 years and rotate them, so the dead one is from 2008.


I'd recommend that a person get the service manual for their camera, knowing the right screws to remove plus the warnings about dressing the wires properly and placement of the light seals are worthwhile.  There are instructions for shimming the lens mount, the focus screen and the sensor, but I'd only do the focus screen, since some high precision tools are needed for the other jobs that are more accurate than my 1/1000 in dial indicator.

I use frog tape doubled and stuck to my workbench in several places and place the screws on it in the approximate location that they came from.  This keeps me from knocking them off and helps keep them organized.  I also have a pretty good assortment of various sized screws just in case I lose one.

EOS Bodies / Re: Are you planning to purchase a 7D2
« on: Today at 02:30:29 PM »
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.

If its like the D1 X, it will have a separate processor for autofocus.  The speed of autofocus not only depends on the lens and processor in the body, but on the battery voltage.  A higher voltage battery can drive the lens AF motor faster.  A used 1D MK IV should still be a better choice than a 7D MK II for your use.

I had two 7D's, 5 40D's, along with other APS-C cameras.  Even the entry level FF bodies have better IQ and are cheaper, In fact, I picked up a old 5D classic for $350 last weekend, and its better as well.

Better than what?

Better IQ than any APS-C including Nikon bodies I've owned.

Lenses / Re: Help deciding on going full frame

Decided to bite the bullet and have ordered the 6D, 24-105 and 16-35 f4. I should have delivery in a couple of days and am looking forward to playing with my new toys.

Let us know what you think.

Format a used CF card in a computer just before placing it in the new camera.  Otherwise, the image numbering will pickup from what was on the old card, and its nice to have it start out with a low number on a new body.  If its a new card, no issue.

I use Reikan Focal almost immediately to adjust the AFMA of all my lenses. I have all my targets printed out and setup in preparation for receiving the camera.  I first verify operation of the camera with a few shots, but do not try to photograph anything seriously until I've calibrated the autofocus.  Normally, most of my lenses fall within +/- 5 points which is the Canon tolerance, and being off by 5 points is not a huge issue.  However, some lenses exceed the 5 points, and then AF accuracy is a issue.

AF accuracy can be a camera issue, a lens issue, or both.  If, for example, the body is in spec at -5 and the lens is in spec at +5, the results will cancel out.  But, if they are both +5, then the result will be a AF issue, and a -10 needed to adjust it.  That's a extreme case, bodies tend to be very accurate, but it happens and is easy to adjust.

I bought a old 5D classic lest weekend, it had a scratch on the lcd cover, and the tine / date battery did not work, so I had to reset the time / Date every time I replaced the main battery.

The LCD cover replacement was easy, I bought a replacement from ebay for $4.88 and replaced the old one in 5 minutes, its something I've done on other cameras I've owned.

I also decided to try fixing the battery issue, and found a free download of the 5D classic maintenance manual online.  It turned out that disassembly was easy.  I already have JIS type screwdrivers required for screws on Canon lenses, and the rubber covers on the camera body peel back easily to get at screws to disassemble the camera.  I'm at a disadvantage with my big fingers and poor eyesight, but still managed to tear down the camera to where I could get at the button battery interface module to remove it.  That's where I hit a snag. There are some fine wires going thru a ferrite core that is glued to the module, and I'd have to completely disassemble the camera right down to the mirror box, unsolder the two wires to pull it out.  That seemed excessive to me just to get that little part out, and I think there was only a small chance that a new one would fix the issue.

Still, for most repairs, like replacing the main board, or replacing the CF card slot, it would only take a few minutes and is a quick and easy repair.  There is no need to disturb the sensor or any of the critical parts that must have precision alignment with special tools.

Because the 5D is such a old body, parts are relatively cheap, so doing it yourself is a option and messing up a repair on a old camera would not be a huge loss.

Is it spec'd that way?  I could not use AF at f/11 with my 1D MK III and live AF.  Sometimes when pre=focused to be close, it would snap into focus.  I never tried it with either of my 7D's.  My 5D MK III acts much like the 1D MK III, is occasional snaps in to focus at f/11 when using live AF.

I don't think it's spec'd at all.   But the 7D + 100-400 + 2xII combo focused reliably, albeit slowly (even if IQ was nothing to write home about).

I'm not expecting to get a 7D MK II, but I am interested in being able to reliably autofocus at f/11.

Canon General / Re: CPS Canada - No (more?) welcome package?
« on: August 26, 2014, 11:32:29 PM »
Canada might be different, but in the USA for the gold level you get:
1 CPS Pro Strap
1 Body Cap
1 Rear Lens Cap
CPS ID Card
CPS Pin

Plus some labels for addressing your equipment when you send it to them. Upon renewal, I just got a card, labels and a repair form.

Not for renewals, just for new members.

And, to further confuse the issue, the 70D will autofocus f/11 lenses.  This is only possible while using live view, autofocusing of that 400mm f/5.6 lens with a 2X TC attached is allowed.

I'd expect to see this feature on the 7D MK II, but no live AF beyond f/11.

Even the current 7D will AF an f/11 lens (e.g. 100-400L + 2x) with live view, using contrast detect AF.

Is it spec'd that way?  I could not use AF at f/11 with my 1D MK III and live AF.  Sometimes when pre=focused to be close, it would snap into focus.  I never tried it with either of my 7D's.  My 5D MK III acts much like the 1D MK III, is occasional snaps in to focus at f/11 when using live AF.

« on: August 26, 2014, 08:17:37 PM »
So, Click and neuroanatomist, why do you recommend B+W over the Canon brand filters?

Mt Spokane Photography, why did you switch to non Canon brand?

Don't get me wrong, I have nothing against buying B+W or other brands, I'm just curious why the seeming recommendation to avoid Canon filters except when unavoidable.  Price?  Quality?  If you could elaborate I'd very much appreciate it.  Thanks.

I switched to B+W and Helicon based on the many reports from filter users, and saw no bad effects from the Canon filter, it went with the lens when I sold the lens while moving to FF.  I also noticed a benefit from leaving filters off the lens when using it in studio, the images seemed clearer with more contrast, but that could be just me reacting to suggestions from others.

One item that has not been mentioned, is the nasty tendency of the cheap filters made with aluminum rings to gall on aluminum filter threads and become stuck on your lens.  Filters using brass rings like the high end models are not going to have galled threads and be semi-permanently stuck to your lens.  Brass filter rings do sometimes require use of a filter wrench, but do not require extreme force to remove.  The aluminum galling is mostly a issue with aluminum threads on lenses.  Canon is switching to plastic on some newer models, I don't know how this will affect filters getting stuck, but its likely a improvement in that regard.  For example, the 16-35mm f/4L has plastic filter threads.

As I said, my MkIII's (though they are 1Ds's) slow down when I put SD cards in them, the fastest rates I get with the various cards I actually own are when I just have Sandisk CF cards in the CF slot and nothing in the SD slot, every SD card I own is slower than the various CF cards I own.

You are correct.  Even the fastest SD cards are blown away by a fast CF card.  In a mark III, the fastest write speed you will get with SD is 10mB/sec, most are 5.  The card specs are misleading to a extreme.

DPI does not affect jpeg file size. Number of pixels does, as does content (more detail bigger files), noise, iso (because of the noise), quality setting etc.

Makes sense, I have no excuse for my senility ;)

With Lightroom, you set the DPI of the jpeg image, so its another variable.  I sold the D800, at high ISO, those 50MB nef files uncompressed to over 150MB and took a long time to post process.  I used a huge amount of NR, and then any resolution advantage was lost.  Since I tend to use mostly high iISO like 12800, the camera was not the right choice.  My Nikon 24-70 2.8G had a ton of CA.  I thought it was defective until I read the fine print in the reviews.  I was using it at 24mm to take group photos, but the edges had so much CA that Lightroom could not correct it.  There is more to a camera system than a sensor.
