but analog or digital, the "warming up" process is the same right. My friend asked me to get digital one because the analog one takes a longer period to dehumidify. :/
i am using the aipo dry cabi
it is consider as close loop
for the other it is like open loop.
ie it is always operating.
Open looped, close looped is up to you. Constantly operating is fine by me considering the power consumed is only 5W for a single chamber one, and 7W for a dual chamber one. So for a open loop dry cab that runs non-stop, it costs 2.6 cents a day to run ( power bill in SG now is S$0.2169 per kWh), which means around $0.85 a month in electricity bills.
thanks man, so its okay to go for Digi-Cabi DB036?
agree on that and 2.6c. juz that imho, if i can save abit on that power usage i am doing that small bit in helping save mother earth.
Sure thing. Whatever helps mother earth. All of us should also make sure we conserve resources in other areas as well. Some of our most simple habits may be the most damaging...
You are using Manual mode, where you set both the shutter speed and aperture. If you do that, you are supposed to control all the variables of the exposure. The meter only "informs" you of the metering estimation in the metering bar and takes no action for you. When you change EV compensation, the meter reading will change (on the bar), but since you told the camera you are the master of the exposure (M mode), the camera will do nothing in terms of exposure. Try your experiment again in A or S mode. And see the difference. Notice how the shutter speed and aperture value changes for each shot. And you will understand how EV compensation work.
Or you can read this: How does EV really work?
BTW, if you are very new to DSLR, you need to understand how your camera works, and you should not start with the M mode, without a solid understanding of exposure. I suggest you start reading and learning here: http://www.clubsnap.com/forums/showthread.php?t=309544
hi guys, i was reading up on different brands of prime lens for past few days..
and more or less, i've set my eyes upon the sigma 50mm f1.4d prime..
anyone using this prime on their d90? care to give comments? :angel:
By Thom Hogan on Sigma 50/1.4 compared to Nikon AFS 50/1.4G :
The Sigma is bigger and heavier physically. Optically, the two lenses are close cousins in terms of performance. If central performance and bokeh (e.g. portraits) is most important to you, I'd slightly favor the Sigma. If overall performance is most important to you, I'd slightly favor the Nikkor. Autofocus performance is slightly faster on the Sigma at the expense of manual focus precision.

Personally, I am using the Nikon AF 50/1.4D. It meets my needs and it is a lot cheaper.
i see, how much cheaper is the nikon prime? $300? :dunno:
if buy from shops, do they allow you to test each individual lens? :sweat:
You only test the one you are about to buy (after confirming you are buying that lens). If you encounter a real problem with the lens, highlight the problem to the staff helping you. And they will bring another one out for you to test. If ok, pay, take and go.
No, you cannot ask them to bring out several copies, and you test all and select one. That is very bad etiquette.
As for pricing, feel free to check the Nikon price guide in the Price guide subforum. Just to let you know the Sigma is the most expensive, followed closely by the AFS 50/1.4G , followed by the AF-D 50/1.4D

from what i heard from many sigma users.. the exterior coating of the lens tends to peel off after a prolonged time. So maybe this is another factor to consider. Frankly i've tried the 50/1.4 before from nikkor and i think its a solid lens. :thumbsup: you can go flickr to look for samples.
