<p>The biggest advantage of the zone system is possibility to adjust both EXPOSURE and DEVELOPMENT for particular scene contrast. Using large format box camera allows you to do it for each frame, as each sheet can be developed separately. For medium format cameras you can have at least three interchangeable film backs: for contrasty scene and N-1 development, for normal scene and N development, for non-contrasty scene and N+1 development.<br>

In the case of 35 mm 36 exp. film using the zone system is very limited. If your camera meter is properly calibrated for your film/development you should be able to achieve similar results without it.</p>

<p>I agree with Andrew. <br>

During my trips I usually take 500 photos/week - I believe most people takes twice as much... :-) I use Canon 70D so RAW file size is almost identical with 6D. 64 GB SDXC card accepts ca. 2000 photos. I've just found Lexar Professional 64 GB 633x (150 MB/s) SDXC card on eBay - 47.99$ for 2-Pack. <br>

I'm not sure about possibility to push you photos through wi-fi. Depending on local network speed it may take you more than two months... :-)</p>

<p>For a couple of years I'm EF-S 18-135 STM user, and must say I'm more than happy with it. To be honest - for last two years 99,9% of my photos were taken with this lens.<br>

Optical imperfections (distorsion, chromatic aberration, vigneting) can be easily corrected with DPP during RAW processing.</p>

<p>Did you try Canon software supplied with a camera? In my opinion it's the easiest and the most accurate way to read exif data form Canon files.<br>

And you don't have to buy it... :-)</p>
