 But I'm glad my first time didn't come within days of buying a new camera! 



That was my premise

Read online that this shutter count is normal, it is not 0 .

FeatherScope

Do new cameras have 0 shutter count, because one of the first pics i took shows shutter count of 63 , i would have taken 10-12 pics max before this so 63 means it was already used before.

I am so lazy. My liquid and swabs are within arms reach at home, whereas the service centre is far away.

I was at the Chennai Imaging Expo a week or three ago. Sensor cleaning was on offer. I decided not avail, preferring my own touch to that of a a guy working fast with a full in-tray!

It is only scary the first time. But I'm glad my first time didn't come within days of buying a new camera! 

FeatherScope, you can have big spots on the front lens element without it noticing much, if at all, in the image. Rear element is worse, sensor will always show.

One thing we are always reminded of in these conversations: it is not your sensor you are touching, it is a thin sheet of glass cover. It is actually much less fragile than your shutter!

Short answer: take it to a nearby Authorised Service Centre and get the sensor cleaned.

It is probably sensor dust, i wiped the outer element of the lens which did not fix it , the spots were there on the exact same areas after the cleaning so its either sensor or the inner element.

I have ordered the ziess lens cleaning kit, which has the blower. Will try vibrate and blower after i receive the kit. I bought this from flipkart, the spots were removed by the dust removal function in lightroom.

It certainly looks like sensor dust.

This is the standard test for sensor dust. Stop down your lens (make the aperture smaller, f11 orf16. Engage manual focus. point the camera at a plain surface (white paper would be ideal, but anything will do.) and make it out of focus. Fill the screen and take a shot. Take a few shots, moving the camera a bit between. Spots that belong to the camera will stay in the same places, any spots that might have been part of your subject will move.

Did you buy your camera from a shop? If so, maybe they would clean the sensor for you.

But wet cleaning is not the the first answer. Use a  puffer, and use the camera's vibrate function. Frankly, the vibrate function is pretty useless in older cameras that don't have the supersonic shake.

You should have a puffer. Do this regularly. Only sometimes do you need to do a wet clean.

But here's the thing. The first time that you do it, is is very scary. You soon find out that, actually it isn't! Buy the right kit, watch a youtube video or two, and go for it.

Here's the thing you must know, and which makes it less scary. Most of us, first time, don't know this...

Cleaning mode (vibrate) locks your IBIS. Do not leave cleaning mode until your wet clean is finished.

Dust is a thing. It happens: it is part of living with an interchangeable-lens camera.
