<p>Hello,<br>

<br />I am intending to attach two Vivitar 2000 flashes to a dual sync cable into the sync socket of my OMD EM1. I understand that the max trigger voltage is 250V and the Vivitar flashes each come in at 190V. I am not an electronic expert, but wanted to understand if the voltage is likely to combine in series and thus be a bad idea or if it will be ok. Any suggestions gratefully received.<br>

Thanks.</p>

<p>I moved from Canon 5D and 7D. My back thanks me, but there are some compromises.<br>

Battery life is poor. I have 4 spares, but 2 is usually enough for 700 shots.<br>

AF is not yet as good as the 7D, but I tend to use single AF plus MF for airshows etc. I will keep playing with the C-AF, but to date I have found it useless. Maybe the 40-150 2.8 will help. I find the 100-300 (Pani) hunts the wrong way first and I have missed shots. I tried the 40-150 and fell in love.<br>

Would I go back to Canon? No as I like the weight and quality, but if I needed full frame the Nikon 750 would be tempting.....</p>

<p>Good Morning,<br>

<br />I believe it is possible to improve speed of Photoshop by running the application from a second HDD / SSD. I have installed a SSD into my laptop as a second drive, but am having difficulty in installing PS and Lightroom to it. Can any kind soul help? The drive is initialised and working.<br>

<br />HP Envy 17 running Windows 8.1 64bit. 16GB RAM, Drive 0 1TB HDD and Drive 1 128GB SSD.<br>

I use Creative Cloud as a PS subscriber.<br>

Many thanks in advance.</p>

<p>I have an aging 7D and having dabbled in more compact replacements such as the Panasonic G3 (didn't like the colours) and some pocket compacts alongside the 7D; Fuji x20 (lovely, but limited range) and Olympus Stylus 1 (good, but not quite fast enough), I am trying to work out if I could replace my 7D and the compacts with something lighter without too many compromises. I shoot a wide variety of subjects, but enjoy telephoto work with some action. The cameras that I am considering are:</p>

<ul>

<li>Olympus OM D EM1 - Key points 81 point AF and in body stabilsation</li>

<li>Fuji XT1 - I tend to like the Fuji sensor results, but lack of telephoto options</li>

<li>Panasonic GX7 - Fairly similar to the Olympus under the shell</li>

<li>Sony Alpha A7 - Full frame, but compact.</li>

</ul>

<p>Looking at the specs, I suspect that the Olympus would be best for me, but I have concerns over AF speed and viewfinder tracking of subjects. Does anyone have some practical experience with any of the above that can help me understand the major practical differences? Main uses will be street, macro, action and wildlife.<br>

Any real world advice would be appreciated.</p>

<p>Downloaded the trial and after a Nvida display driver upgrade direct from Nvida not through Windows update it works fine - initially froze.<br>

Elements 11, Dell XPS, 4GB RAM Windows 8.</p>

Can anyone recomend a good value and good quality photo book printer in the UK? Photobox have been a bit hit and miss of late.

Thanks.
