A video will tell a lot in my case... i just recorded it... is it normal?? before that i didnt heard any of this sharp noise... cant believe it happened after a few days... is it faulty??       

Adjust some white balance, adjust some hue, adjust some curves, do some split toning on the highlights and shadows. Voila~!

Hmm, I used one of the presets from LR. The adjust to what I want

Maybe you need to pindah to another state 
Haha...
But you have some point , some shop owners will do like that...

lol they are more like your underling le... the more they give the face the more they out of business so when they make that face just smile back  I always got that look le...

I mean test it out and then walk away? think they are going to still smile at you ar?  just ignore the face and test 

Though in japan I can sit on their couch for sale for hours and still none of them show me the face or anything... more like they smile and happy 

reminds me of the incident where my sister was ordering some food and then got a call for urgent meeting .... told the waitress to cancel and give back her money... in the end she got the food and the money back... reason if you might ask... is "can't speak english"  though japan is a good hospitality country 

KK is a nice place to buy stuff. And Tokyo... man... whole shops full of 2nd hand lens going for cheaper than a meal sometimes... Can try the lenses, cameras, fool around, and even if you don't buy the next time you go there they'll still be as nice as ever. Makes you feel bad.

Oi cheap!!! RM80 I also wanna go!
That's Japan for you. Especially in tokyo, proper ethics is very important to them. I got scolded by my Jap teacher because I used osaka slang while in class(which is a bit rude compared to proper manners Japanese in text books).

Nobody answer? Nevermind, I will use my experiences and tell you. So if anyone would like to add further details or do some corrections, please do so 

Firstly, check the outlook for both Body and Lens, if you're happy with it, then proceed to the next stepsssss. 

For the Body:
1. check the Shutter Count, the lower the SC, the better it is, just like a car's milage. Google has a clearer explanation.
2. if the Body has motor and top LCD, make sure they both work well, it's sux if the motor doesn't work, it's sux if the top LCD can't light up.
3. test the Body with various memory cards, you don't want to have error while shooting, don't you? (sometimes it's the memory card that give trouble)
4. test Continuous shoot, will the shutter jam? 
5. basically you'll have to test everything, every single functions and settings of the body, like ISO, pop-up flash, the condition of hot shoe, the buttons etc etc

As for the lens:
1. it's important that the rubber is still firm.
2. make sure it works on more than ONE Bodies.
3. play with aperture, the zoom if it has, play with it like a toy.
4. if the lens got dust and fungus inside, you can send it for cleaning.
5. if the contact points are dirty, gently use eraser to clean it.
6. if the lens is AF-S, make sure the motor inside is silent while auto focusing, no loud squeaky sound.

what else?   

Remember, these are based on my personal experiences, correct me if I'm wrong
