>>3012118Nope, be wary of rain, cos it's wet and in the air, apart from that your camera will be fine.
>>3012157No, it's shit, has no screw drive focus motor, so you're stuck with only the most expensive lenses. A 2nd hand d7100 is a better choice for lifespan, it will last you until you want to pay for full frame, might be a week, might be 5 years.
For a beginner though, you would be a thousand times better off with a sony mirrorless, an evf (electronic viewfinder) has many benefits; it's much larger than any crop optical viewfinder, you get a wysiwyg preview of your image as you change settings as opposed to just looking through a window and relying on metering, it has focus peaking and focus mag which are fantastic for making old cheap manual focus lenses much more usable (you can put ANY lens on sony mirrorless cameras using a $10 adapter), it will give you a clear preview even in a very dark room. There's also the matter of price/performance, because every mfg but canon buy all their parts from Sony, Sony can do it all cheaper. Not to mention the cameras are much smaller and more aesthetic, so you won't look like an autist with it hanging round your neck and you'll be more tempted to take it out with you.
When it comes down to image quality, there is almost nothing in it, sonys 24mp sensor is in pretty much every crop body.
>>3012162A decent hardware calibration tool is designed to be left on your desk so it can take readings for the light in the room and adjust your screen on the fly. They have a long lifespan and aren't expensive.
