<blockquote> <p>Or sunscreen or mosquito repellent?</p> </blockquote> <p>Very likely but it happens anyway. I'm in temperate Denmark and it happened to my keyboard and mouse. I think the softening agent in the "rubber" paint breaks down and dissolves the "rubber"<br> </p>

<p>NEVER use acetone or thinner, it dissolves plastic!!</p>

<p>On other types of equipment I have had success with removing stuff like that by removing the biggest lumps with nails or a credit card and then a lot of polishing with alcohol or white gas. It can look quite nice underneath. But printed matter on the rubber, will of course also disappear.</p>

<p>You changed position between the photos. Is the ceiling darker in the middle of the room, or is it much higher?</p>

<p>I have two cards and I can see they are called Red and Orange, so I must have named them when I created them.<br />My cards are matched to the EyeFi program in my PC, that I used for configuration.<br /><br /></p>

<p>I just bought a Sigma 150-600mm C. I think and also according to reviews, that this is where you get most out of your money. It costs below 1000$</p> <blockquote> <p>The Sigma 150-600 Contemporary is a very good lens, with an outstanding performance to dollar ratio, and the build quality feels excellent. It's a great bargain, given both its versatility and the prices for the alternatives from the major manufacturers. While image quality isn't super tack sharp, especially at 500-600mm (and the corners aren't as crisp on full-frame cameras), if you factor in all the cash left in your bank account as opposed to purchasing a 500mm or 600mm prime lens or something like the Canon 200-400mm f/4 lens, you'll be thoroughly impressed and chuckling all the way to the bank.<br /><br />http://www.imaging-resource.com/news/2015/03/30/sigma-150-600mm-contemporary-lens-review</p> </blockquote>

<p>Even if you have 30.000$ "Due to the specialist nature and demand for this product, the ME20F-SH will only be available to selected partners."</p>

<p>There definitely is a battery in the sender. Its also obvious, as there is an LED on it. It should light green when you push the grey button halfways and red when fully.. <br />Sorry, I can't be bothered to take mine apart, you'll have to open yours to find out what battery it uses ;-)<br /> The button on the receiver(square device) is the on/off and the right LED should come on. The left LED goes green when the button on the sender is half pressed and red when fully pressed.<br /> The unit works flawlessly and the batteries last for ever.<br /> I'm afraid a unit using AA batteries would be rather clumsy.</p>

<p>When trying out converters make sure they are compatible mechanically as well. With some combinations you can have the lens extending into the converter, when zooming or focusing! ! !</p>
