that's why u need to turn on the cleaning mode.. in cleaning mode, the camera will pull up the mirror but in the same time cut the charges to the sensor.. so it's safe to dismount the lens and blow the sensor

AlphaBeta, the sensor is behind the shutter. Go push your mirror up right now and see that your sensor is not exposed at all!

(The mirror will stay up, so turn it off and on again.)

The charged sensor only comes into concern if you try to access the sensor by shooting a long exposure and removing the lens.

I have managed to blow dust out without the body facing down so it's not a big deal.

If you:

Turn on cleaning mode then remove the lens - okay
Remove the lens then turn on cleaning mode - still okay

The sensor only gets dust when an exposure is happening. When the mirror and shutter is down, dust would not be able to settle on the sensor. Think about it, how long does it take for dust to settle on a surface?

Oh and happy (belated) birthday signither!

Sensor cleaning video by albnok is now posted on the 1st page!..

yup, that I am doing for my cobra. . The shop, YL in pudu plaza did not fill in the warranty card. They just putted their company chop on it. . I only will register my cobra after a year or 2. So, I have 2 or 3 years warranty instead of 1. ;P

chiggyy, were you at Fashion On 1 today? If am not mistaken, you were wearing red shirt right? .. I wanted to say hi but you look 'too busy' with people next to you. .

hey guys, i wonder why i cant register online my alpha200 at http://www.sony.com.my/mysony. Is there any problem with the system?

make sure you remove - symbol in model, DSLRA200 or something like that. Look at the model at the bottom of your camera. .

guys.. my first hdr.. ok or not? i really dont know how to do tone mapping in Photomatix laaa..



please comment and give advice on how to improve.. btw, again, i dont know what is tone mapping and i just hentam..

Haha, I face this problem same as finalfantasy before. I believe many of you also experience that. Just key in DSLRA200K (for single lens) or DSLRA200W (for twin lens).

AlphaBeta, because the shutter curtain still blocks it.

In the film days, the shutter curtain was necessary to block light from exposing the film.

For digital sensors, the shutter curtain is still necessary to avoid 'rolling shutter'. I have a digital camera without a mechanical shutter and it gives a rolling shutter effect much like what you see on the D90 video mode:



The shutter speed was very fast on these images mind you! About 1/1000s if I remember correctly.

amadeo, thanks!

i want something reliable and not too exp.

my suggestion will be sanyo eneloop, maha imedion, and maha powerex..wat speelite u bought bro?

Get Sanyo Eneloop. Self discharge rate for Eneloop is very low (even in 1 year, Eneloop retains 85% of its power).

Other rechargeables eventhough have higher capacity (Eneloop 2000mAh, others 2500-2700mAh) but some of them do not charge all the way to their stated capacity, hence you'd get a less than <2500 - 2700mAh.

You mentioned you want something reliable... hence go for Eneloop. Even after several months, you can be asured that it still retains its charge / power.

higher capacity means u can get higher recharge time..

also important shooting events

thanks for the opinions...

afraid to get the maha batteries.. in photomalaysia or in some other forum (forgot), i've read that quite a number of people buying maha batt (forgot what model) having their batt discharged substancially in about 3 days only..

Yes, very important to always have the charges available in your batteries.

What I would suggest, to be on the safe side, get 2 sets of Eneloop batteries full charged when going to those events. Even if finish one set, you still have another backup set to use. Hence your charge capacity is double.. ie 2 sets of Eneloop = 2000mAh * 2 = 4000mAh.

Once you have charged your Eneloop to its fullest, you can have peace of heart confident that even after 6 months or more, the charges in the Eneloop are still there. No worries...

Where as for other rechargeable batt, you would not know with confidence how many charges are still there in the batteries.

Hence, Sanyo Eneloop ftw.

Since we are using Sony, dont you guys think about sony cycle energy battery? .. ..

I am using it and as I know, it is same as sanyo eneloop, hold the charge for a pretty long time. . So far so good for me. Today, I was shooting about 1.2k shoots using it on my cobra at 1/4, 1/8 and 1/16, and guess what, it served me well from the 1st shoot to the final one eventho i charged them a couple of weeks ago. .
