1hr can net u about 200-300 snaps (around 30+%)

when using on apsc always multiply by crop factor....when using on FF..u get whats stated on the lens..


@zstan
my a850 batt i mean. >.<

is that battery grip good to use cos thinking buy or dun want buy haha

and about my DT lens?

i dun think u can fit aps c lens into a full frame body?

i thought the connections are different? or maybe some can? correct me if i am wrong.

@achew
haha.1 hour about 30-40% la. dun use live view or long exposures or pop up flash can save batter.

Added on June 15, 2010, 5:42 pmor if u want to save even more:

1.completely turn off ur LCD display

2. dun bother checking ur pics after taking

ok that's a bit extreme.

><

IINM can fit and use . but will automatically change the MP to lower ones or picture come out gila vignetting.
but i read somewhere where we can trick the camera or something, kena tanya albnok..

1 q: if you have a dry box, must we put the body inside the dry box also? body dont get fungus rite??
(if the drybox is small )

Every focal length on every lens for DSLRs are stated in 35mm terms, i.e. Full Frame terms.

Thus the 70-300mm is correct focal length for FF as is the 18-70mm.

A DT lens simply designates that the lens is meant for APS-C sensors only. You can still mount it onto the A900/A850 but you will get vignette looking through the viewfinder and the output will be automatically cropped. The focal length is still stated in FF terms.

lol..i don have liveview or popup flash...

but i do need long exposure for 1~2min each shot ^^

but heavy humid will depreciate anything..

hahaha u get confuse?

like this. its jsut a measurement for the lens. 18 still 18mm, 100 still 100mm. but its the sensor that crop the whole pic.

FF shows the full framed of the lens, while, since crop sensor is smaller, they capture the middle area of the full frames.

now, when u crop the frame of the pic, meaning u zoomed in the pic (tighter framing)....

so, on crop sensor, when u get a 70mm and shoot from a crop body, u get a zoomed framing, meaning if u get a FF body, u snap at 70mm, but u crop out the middle area, that frame, which u can capture with FF by zooming to 105mm.

so, when u capture a photo with 70mm on crop, u need 105mm on FF for the same photo frame. hence, FF is not so excellent for super tele, which crop, given a 500mm, u get a 750mm zoom power.

Thank ok lah will bought this weekend hahaha

ok get it.. now i'm so tempting to get another extend of telephoto lens..

ok. then u r in deep trouble.

how many shots u plan to take?

maybe u can bring 4 or 5 extension cords and plug it into the nearest power source u can find.>.<

i assume u have more than 1 battery?

DT lens is same like FF lens, since u always snap the middle smaller area(crop sensor), they remove the extra corner area to make the lens smaller...

so when u attach a DT lens to FF, new FF DSLR are smart, it detects DT lens, and automatic change the sensor capturing mode to APS-C (crop mode)

but if u use DT on film camera (35mm = FF) u will see the internal of the lens show up around the corner of ur photo

DT can be used on FF and crop camera. just that in FF body, it will not use the full megapixel sensor, it uses the middle crop size area, hence u wont get the full MP (A900 =24mp) but get the cropped version MP (not sure how much, i think around 12mp)

ah i'm sensing another once in a bluemoon landscape again , love ur work btw

8tvt : kena fund for big big one
