shite!CMOS奶野...有幾點黑影....光圈收到11就好明顯...點算?

[Obi-Wan]

not a serious problem, low pass filter of CMOS get dust

Solutions
1. don't use small aperture, OR
2. clean it yourself (beware, sometimes u can induce more dust particle into the low pass filter if u a cheap cheap pump with much dust inside, OR
3. go to CS, they may charge u

買什麼來清潔??THX

吹o下先啦, 你用緊邊個model, 400D以上的, 吹完再震o下佢, 唔好亂落solvent.

[kp3618]

50D......吹o下....震o下....i will try...thx

dchome o個有篇文前幾日post.. 圖文並茂... 可以去參考o下 : )

可以試吓這個Artic butterfly. 上次部機奶野,都是自己清潔番! 用之前一定要看清楚說明書. 天搶有得買,但它一定搶你!

I use compress gas to clean (successful for many times)

Don't use cheap cheap pump because last time a cheap cheap pump induced more dust particles into the CMOS low pass filter, then go to CS to clean

Also don't use solvent or sensor swap before pumping with gas, otherwise some sand particle may scratch the low pass filter if use sensor swap. ONLY USE SENSOR SWAP IF U CANNOT BLOW THE DUST OUT WITH PUMP OR COMPRESS GAS

icic....which COMPRESS GAS will be better?and where i can buy it?how much?sorry for many question but i rearly want to know more about CMOS because i think it will be always 奶野 in the future...........thx

SSP $75, MK $98 to $200, WC 298 $78, all brands compressed air works the same, not do not use the CAN upside down, 1st test on your hand, mount the camera on tripod, set manual sensor cleaning, the mirror will be up, press the compressed air button, DONE!

DO NOT USE SENSOR SWAP UNLESS THE COMPRESS AIR DOES NOT WORK
