<p>Earlier bodies had a CF setting that set the shutter speed at 1/200 when using flash. The menus and CF for the 7D have changed when compared to older bodies but I'd look for such a function in the menus.</p>

<p>Sekonic L-308S measures flash and ambient.</p>

<p>With Canon TTL you probably mean E-TTL, which gives a preflash. The latter will trigger your manual flashunits and at the time their flash is required it's probably not ready.<br> Start reading <a href="http://photonotes.org/articles/eos-flash/">http://photonotes.org/articles/eos-flash/</a> to know more about Canon flash systems ant its in and outs.<br> Since you're (relatively) new to photography my suggestion is to go full manual or full E-TTL for the time being. A mix of these will complicate the process too much.</p>

<p><strong>"I'm under the impression that Nikon has the megapixels but only a few lenses that really match the sensor's quality"<br /><br /><br /></strong>"Not true etc" does not change my impression :-)<br> Of course there is much more to an image than just resolution. Occasionally I still use my 6 MP camera with fine results.</p>

I'm under the impression that Nikon has the megapixels but only a few lenses that really match the sensor's quality where Canon is first opgrading more lenses before releasing a big megapixel body. And of course the grass on the other side always seems to be greener. Think of it, 36 MP is only a 30-something % upgrade to 21 MP, linearly. More and better but less than it looks like at first sight.

OK, I found a few references, file size seems to be limited to 30,000 in each direction AND/OR available PC memory. Your max size is about 10,000 pixels so memory may be the limiting factor. I'd still try Irfanview :-)

I don't know if there are file size restrictions to JPGs, you may check this (Wikipedia?), or you might try another program. Try Irfanview, it's free. And please state the size in pixels, over here it's too late to do the math from inches/dpi to pixels

<p>Fully compatible but if I were you I'd go with an EF-s lens, unless you have compelling reasons to choose the 24-105. This lens is a bit on the long side for cropped sensor bodies so I'd choose one of the 15/17 to 55/85 mm lenses. OTOH if you're thinking of upgrading to full frame in the near future the 24-105 is ok. Also have a look at the Sigma 24-105 which also gets good reviews. Sorry for complicating our choice.</p>

<p>Lightroom runs on Mac and Windows 7 or 8<br> LR mobile runs on IOS 7 (iPad)<br> Photosmith runs on IOS, supports Lightroom for file handling and selection.<br> AFAIK there is no lightroom support on Android.<br> Asus T100 runs windows 8.1 but has only 32 MB SSD storage. Its processor and internal memory seem to be a bit on the low side for running LR but I could be wrong.<br> I'm not too happy with an iPad for backup on the road so I think your choice of the ASUS is in the right direction but I think you need a somewhat more powerfull (processor and RAM) device with more backup storage (usb disk?). I hope others can point you to a more specific device.</p>

<p>Hard to judge from a small jpg but check 2 issues: DOF as stated by Matt and if you are shooting in RAW have a look at sharpening. RAW pictures tend to be a bit soft, these need some sharpening (and noise reduction) to come to the final image.</p>
