okokok lemme explain.

it happens frequently and randomly. whether it's burst at 6fps, burst at 3fps or single shot. it gives me the Err intermittently at various shutter speeds once the err comes out, i off it, take out the lens, i can see that the mirror is flipped up and the shutter is covering the sensor. i then have to on back, press the shutter again then only the mirror will drop. but before i take out the lens, i can see the image review that it's all black. 

mine doesnt have the black line at the top or bottom like the link i posted. but u read what the TS said, he also had intermittent Err probs with the mirror/shutter jamming.

Added on December 28, 2010, 7:06 pmthe funny thing is, i used the cam quite a lot, more than 1k shots as it went to the 2nd folder on my memory card since i got it. nothing happened, went to klcc, icity, church event and all no prob.

until just now, decided to test fast shutter speed. after 2 shots, gave me Err. and then now it keeps on happening quite frequently. i would say once every 3 shots on average.

doing a stress test now to find out problems earlier might be better than dying when u need it or when your warranty is out
i'm using nikon 18-200mm VR1. happens when autofocus is enabled and almost in manual focus. happens in all modes, AF-C, AF-S, AF-A.

heck....even when there's no lens mounted and no memory card, it still gives the Err.

thanks celciuz......that means I can take approx. 5 pix without memory card.....so there is nothing to worry about rite

but then why my pix count didn't even drop when i take pix.......it stay at 1.0k all the time......is this the limit D90 can shows in LCD......I mean the max D90 can shows in its LCD is 1.0k while in actual I can shot more than 1k.......and the number will only start to drop when the remaining size can occupy less than 1k pix??

maybe that's coz it's just wayyy too underexposed.
underexposed or decent exposure is not the problem here. at iso6400, i can still see a very dim image on the times it work. on the ones that show Err. the image is black. black as in "lens cap on" black.
LOL...i can understand why you're saying that. though this is my first dslr for a week, I've been using dslrs for a long time.

my problem now is, sometimes the mirror/shutter does not complete the whole cycle. let's not talk about underexposed or not. what i'm getting is black. total black like as if u had the lens cap on.

this Err problem happens intermittently but quite frequently. on the times it snaps correctly, I get an underexposed image or a normal image. on the times it fails (Err), i get a "lens cap on" black image.

now it doesnt just happen at 1/8000, it randomly happens at lower shutter speeds like 1/60, 1/40. ISO is at auto, so on the times it work, i get a normal image, on times it fail, i get black image but exif still shows the actual shutter speed i set.

when top LCD shows Err. i switch it off, took out the lens, saw the mirror was up and the shutter was covering the sensor. put it back, switched it on, press the shutter button again, and i can hear the mirror flip down. now I can continue snapping.

sorry if this is real long but i cant really think of a better way to explain this as I dont have a video of it. 

so in wat mode i need to use??p , s , a , m .....or other mode??wat this all diffrent??in indorr..like wedding dinner...normaly use wat mode.?and how much iso i need to up??1600?

I wan to ask when taking group photo , where are you all focus at? ? Im new too , when taking more than one person , i hard to make the background blur ><"

I will focus on a person eye when taking one person
 

Hi guys, under what circumstance required to use minimum aperture?

Thanks

just back from wedding actual day shooting. Kitlens 18mm on APS-C also can die. House too cramped. I wished I got an FF body.

I almost used my kitlens like a "18mm prime lens"

I went for f/5.6-f/7.1 for group photos. Saves all my hassle.

Just now actual day wedding shoot for just 6 hours I have spammed almost 700+ shots, not counting shutter spam count tonight for dinner.

how to use f3.6 on D3100 with 18-55?? largest oso i can use is 5.6 o.o

u mean f/3.5 issit?
f/3.5 only available @ 18mm la, when 55mm is f/5.6 max

f/2.8 not enuf for me, must at least f/1.4 

Ask general nic buy for you, he very 'the' kaya

What is function of RAW photos? o.o

yeah.. that's true.
yesterday, I did PP and almost increase the sharpness of every picture I taken with 35mm 1.8.
not really satisfy with the sharpness yet very happy with the bokeh it delivered.

is 50 on DX only good at taking picture? I mean if you want to include a little background w/o move back too much is that possible? 
kind of confuse about the focal range.

50mm does it mean the focus is 50 millimeter from the object? where as 35mm means the focus is 35 millimeter from the object?
it's kinda confusing for me because sometimes, for 35mm I can shoot a very near/very far object and both have the focus. 

need some advice on here. sifu KTCY

that is the tough part. I guess I need to learn more w/ my 35mm 
thanks! 

i own a 50mm on DX, i can feel each of your words deep down in my heart. well spoke bro !!

but nice lens. Take times to master it!

I oso got the feeling of ditching the 35mm and grab the 50mm, coz 35mm to me is stuck in the middle, not wide not narrow, take portrait bokeh not strong enuf, take group pic now wide enuf....    since the 17-50 serve me well more den enuf for walk about lens and group pic, so I thinking of letting go the 35mm and get the sigma 50mm, or mayb keeping the 35mm, see how it goes 1st, best is get both the Sigma 50mm + 35 F2D, haha.... prepares for FX in future

I waited for a long long time to take this model,

1)The crowd walking here and there,they even walk in front of you
2)I standby all the things,camera and post to take this model for long time,I walking here and there few times
3)Have to wait model eye contact with me

BTW I remember all the C&C     
Thanks a lot     

sure?? D3100 taking video can spoil one me?
I mean it is D3100 functionality.
how come if we use it's functionality it can spoil faster?
it's just not making any sense for me   
it's like you have printer which can do scanning. but the sales man said (if you use scanning it can reduce the printer lifespan. IMHO it's not making any sense for big company to give functionality which will reduce the lifespan of the thing)

I took at least 10shots of her,not satisfied with most of them

Sorry my explanation was wrong. my bad! 
anyway got question over here. isn't all DSLR camera will do a long exposure when it come to video?
is it only d3100 problem or DSLR w/ video capability problem?

  sorry I just know that.

if I own d90 I will grab 50mm 1.8D.
I read a lot of fantastic review of the lens itself.
a very good value of money <- People said
feeling like testing myself. and the price is okay for testing. IMHO.
sadly I own d3100 w/o AF-motor    that's the reason I go for 35mm 1.8G instead

im selling off my 50mm 1.8 by tonight...sticking to the 35mm 1.8...and probably get a tamron 17-50 2.8 or sigma 18-50 2.8 later.

^
Reason? isn't prime produce more pleasant bokeh?
somehow.

Cat's eye bokeh on a DX? I didn't notice cat's eye bokeh on my 85 and 70200 on D90.

But on FX, it appears at almost every light source located at the edge of the frame.
