Yesterday I noticed a small speck on my left top side of EVF, I carefully took of lens and saw this little speck o the opposite side of sensor. I didn't have a blower so what the best way to remove ? Or Safest? Can I just blow it carefully with my mouth?

i always change lens with body down, how it got in there, don't know. Was at beach yesterday maybe it was there.

Certainly try your camera's sensor clean function first!

In a pinch, a quick and careful puff with your mouth can be fine. But it is so easy to get spit into that, so I avoid it unless I really need to. I carry a blower bulb, but they are very weak.

I would also recommend canned air - as long as you hold it upright, still and use very short bursts. For stubborn dust, I will take a sensor brush, blow it with canned air to "charge it" which helps dust stick to it, and carefully swipe over the dust spot in a swirling motion.

For what it's worth, one dust spec is no big deal. You can't avoid it.

Personally I would never use canned air. No matter how careful you are there's always a chance it will spit out some moisture. Even if the can say no moisture, it will still be there. Air compressor is a different story though, very safe. Also Arctic Butterfly is a great choice for easy dust removal

Never used the arctic butterfly.

As for canned air vs. compressor - compressors aren't safe by any means - they can have particles and moisture as well. The danger with canned air isn't so much that some moisture will get out, but that it's sub-freezing and can cause issues with the sensor surface. But it's not a great skill to learn and I've never had a problem.

The professional service that saved my butt a number of times used compressed air to work on my sensor all the time.......from a compressor. Probably had a professional filter system. They were pros were the best camera repair service in the Seattle area.

Using canned air inside your camera is the absolute worst thing you could use to clean your sensor. For you to be giving someone in this forum that advise is irresponsible and you should stop!
