EOS-M / Re: Something loose when shake EOS M?
« on: August 16, 2014, 11:05:28 PM »
I think that's normal given the mechanical parts inside.  My M and 6Ds both produce a little noise when shaken and work just fine.

I switched to USB thumb drives and SD cards for delivery a while back when their capacities began to exceed optical media, optical media became optional in laptops, optical media was not supported in tablets/phones, SD card slots became widespread on laptops (even the lowest end machines),  and televisions added USB ports with software to play photos/videos directly. 

It really depends on the media needs of the client.  For example, my 80+ year old mother-in-law much prefers SD media for pictures of the great grand kid.  It's the same as printing at the store kiosk, her home photo printer, or loading onto her iPad from the SD card in her P&S camera.  It also fits in her purse better than optical media  ;)

EOS Bodies / Re: SL1 as a "travel" body
« on: August 13, 2014, 01:19:46 PM »
Got to play with my cousin's SL1 on vacation (we were both traveling) a few weeks ago, with the kit zoom and her 55-250.  She travels a lot and really likes the camera, but what she missed was wide angle so I let her know about the 10-18.  Made her day - it's small, light and will fit in her existing camera bag. 

For me it's an interesting contrast to the M when mounting my selection of lenses from the 40mm pancake to the Tamron 150-600.  It's a bit like a gripped M with an OVF and makes it a bit easier to handhold my larger lenses.  I was a bit disappointed with the OVF, not nearly as nice as the 6D.  I wasn't impressed with the few tests shots I took, but  I didn't have time to fully explore the camera and settings.  I don't think it would take too much time to dial it in, but no AFMA might be an issue.  If so, I would end up using LiveView and might as well stick with the M.

Is that the focal length more longer, the higher percentage the lens need to AFMA?

I think its really about narrow depths of field, particularly near MFD, which faster apertures and/or longer focal lengths exacerbate. 

At 600mm on my Tamron 150-600, at 20 feet you have a DOF of 2" with f/11 and 1" with f/8 so it matters on long lenses even with small apertures.  The 135L has a similar 2" depth of field at 10 feet with f/2.  The 50L has a 2" depth of field at 5 feet with f/1.2.  These are all about twice MFD.

Most kit lenses aren't that fast or that long so they tend to be acceptable without AFMA.  But fast lenses and long telephotos can benefit from AFMA.

My copy arrived with significant back focus at 600 which was clearly visible in shots taken at MFD on my 6D with center focus point only. 

AFMA with FoCal resulted in -2 at 150, -10 at 600 which seems to have corrected the issue.  Sharpness was best at f/8 or f/9, there was a big drop off at f/6.3.  Other tests showed the focus consistency was above 99% at both ends, which is as good as my Canon L glass. 

It still occasionally hunts for focus in low light, low contrast situations which I expected - low being relative in this case.

Looks like the EOS 1D C and 6D are also included.

Used an epson v750 for hundreds of slides, thousands of negatives in different sizes from 70+ years of photography.  The details you can get from old b&w negatives is amazing.   It took a while and some experimentation to dial it in.  Key benefit of this scanner is two pass scanning, one in IR to eliminate dust, scratches, etc.  Highly recommend VueScan for the process, it also has profiles for many different types of negatives.  Not sure if you can apply that to images you take with your camera but you might check that out.

Photography Technique / Re: Help: lightning photography?
« on: July 18, 2014, 01:17:42 PM »
Lots of advice on the net if you search, even some devices that will trigger on a lightning strike.  Didn't find anything useful on Canon sites.

Attended Nikon School of Photography back in my film days even though I was shooting with Canon gear.  The Nikon School Handbook is a pretty useful starting point when I'm not sure, but its at home right now. How to Photograph Lightning on the Nikon School site gives some good advice.

Software & Accessories / Re: Camera bag for camping

Thanks for the tip on camera inserts.  In addition to MountainSmith I found "camera inserts" in various sizes from Timbuk2, Ape Case, and others.  Looks like a nice way to keep your gear all together in one pouch you can lift out of the pack.

In the past I've used some LowePro cases.  When going ultralight I wrap equipment in my extra socks, puffy, sit/sleep pad, etc. which actually works pretty well - no extra weight.  Guess I'll have to do some research before my next trip.  Not sure I want to carry much extra weight.

I use Gregory packs on the trail with my camera equipment (z30, z55) depending on amount of gear I'm carrying.  It's much more comfortable, especially with the additional gear for a long day hike or overnight.  Camera gear goes in appropriate hard/soft cases.  Some packs have both top and side load.  Placement depends on weight, heavier usually goes lower in the pack.  There are good attachment points for carrying a camera on the front.

Pack suspensions vary depending on size/weight they are intended to carry.  It's much better to use a larger pack that can handle the load than overloading a small pack and attaching things on the outside. 

I've had the Nanuk 935 for the last 6 months, but haven't been on a plane yet so I can't report on its airplane/airline friendliness.  I also haven't used the Pelican so I can't compare directly.   No complaints about the Nanuk, it's replaced my other camera bags.  I use it for home storage, car travel, and take it with me to any shoot.  It looks rugged enough and should hold up to normal wear and tear.  I haven't yet had the opportunity to test its construction or waterproofness.  At the time I purchased I got it for about the same price as the pelican.  I do like the latches, no busted knuckles. 

I use a Nanuk 915 for my M gear. 

EOS-M / Re: Arca Swiss plate for EOS M
« on: July 14, 2014, 07:45:28 PM »
For anyone still interested, I stumbled on an alternative RRS lens plate to the B26, etc. for the EOS M adapter foot that overcomes the interference problem when an RRS camera plate is already on the M.  The MPR-73 allows you to flush the back of the adapter foot with the back of the lens plate, providing the necessary clearance to remove the adapter/lens combination without first removing the adapter foot or plate.  There is no room for the flange in this situation, but the flange screws alone still provide a bit of anti-twist support.

Great job.  What were your C.FN II: Autofocus or other settings? 

EOS Bodies / Re: which model is this?

Agreed - 6D.  The screen display is fabricated. Here's the video for some context.

Yep, the manual covers both the N and WG models.  I might have considered the N model if available in the US, especially at a significant discount to the WG.  Haven't really used the GPS yet, but have found the WiFi to be useful on a few occasions for tethering to a iPhone/iPad.
