If you're talking about teleconvertors, then yes that you will be taken into account as optically the focal length is changed. For DX versus FX, the only differences is FX up to the very edge where else DX only in the middle of the frame due to smaller sensor size.
I agree with what you said above about focal length but if you look into the smaller and more dense DX area, the errors will also be enlarged. A micro shake would be more pronounced when you view a picture taken from a DX body. The effect of viewing 100% on screen with DX body is equivalent to viewing 150% on FX.
The rule of thumb to take the crop factor in is not because the focal length automatically extends by 1.5x but more so because with a DX body, you are at a higher magnification and you would be more prone to errors and hence a guide to take into account the crop factor is a prudent rule of thumb.

Add on regarding the rubber thingy, when you fit the MB-D10 on your D300/D300s/D700, the rubber piece will be removed and slotted on the MB-D10, thought it might have dropped off when he detached the grip.
Thanks for the tip. I actually did not realise that the cavity in the MB-D10 is to put the rubber piece.

I worried later I put in a wet table and it kena water
Will it ? I try to avoid.
Putting on wet table is asking for it, yes?

You need a lot of water on the table and long enough that the water can seep in.

Yeah. It's wayyy heavier than the kit lens, but with more solid handheld. Now I'll be carrying D7000 + BG + 17-55 + SB-900 weight for the entire day of shooting!

Comparing body and lens, that's not heavy. D700 + 14-24mm f/2.8 is more heavy !

Yupz. Just got it recently and now gotta make myself familiarize shooting with it

Great. How are you liking it? Any regrets?
QUOTE(BenSow @ Jul 9 2011, 07:36 PM)
Neat trick. Thanks for sharing.
QUOTE(vearn27 @ Jul 9 2011, 07:40 PM)
On contrarily of what you're sharing, you feel that 1.5x crop factor is not necessary to be included in Rule of Thumb for DX or crop-sensor body?
Hmm... it does make sense, isn't? 50mm on FX will be 50mm while 50mm on DX will be 75mm. It takes 75mm on FX to produce the equivalent photo of 50mm on DX and vice versa. Still thinking of the logic of this...
I agree with what celciuz mentioned about DX is just a cropped part of the FX sensor and still coming from the same origin.
For the example you gave, 50mm is still 50mm on FX as well as on DX. Just the
perspective on the DX is like 75mm on FX.

Con? At the expense of greater weight and size?
17-55 weighs 760gm, adding in vr will probably add on almost another 300gm...ie. Getting pretty close to 80-200 weight territory.
The weight will be more like the 14-24mm f/2.8 (with no VR

)
The 80-200mm f/2.8 is more like 1.3 kg already.

I guess, short focal length won't need VR so much..
I mean, according to the Rule Of Thumb..
That's right. But some will argue why Nikon came out with the 16-35mm f/4 VR...
QUOTE(Everdying @ Jul 9 2011, 10:18 PM)
well, lets put it another way.
for short focal lengths, if u want to shoot landscape seriously u will have a tripod.
if u want to shoot concerts, dances etc, ur shutter speed will be high enough already.
plus if u cant handhold short focal length at say 1/30, means technique still needs working on.
i've always said VR shouldnt be a substitute for bad technique, but enhances ur shooting.
VR imo only useful for long lenses especially when shooting low light concerts / night stadium etc.
so say using 300mm, instead of being limited to 1/300s without VR, with VR can go down to 1/125, 1/160s which is still enough to capture avg movement, and gain at least an extra stop of ISO.
Spot on.

Okay, here's the photo. Taken with D700 and D90 with different settings as per in the image. All images taken from the same distance, which explains why on the D90 image looks bigger. Images are zoomed to 100% then print screen and paste on mspaint.

I uploaded the whole file to my flickr, file size is 17mb so be patient. Link to the full size,
http://farm7.static.flickr.com/6030/591881...13c7522bc_o.pngThanks for the effort to show. But doing some sort of a lab test to show that you can shoot at 1/8 second on DX and FX and yield the same results is very subjective. You need a more random test to shoot both cameras side by side and statistically, you fill find that your D90 shots would have lower yield due to "more" camera shake.
QUOTE(celciuz @ Jul 9 2011, 10:55 PM)
If blur due to handshake, does the distance matter? I mean if nearer it would be even more obvious if there's any shake.
Of course... While the angle of deflection is the same, the amplitude of shake is different for subjects shot at 5m and 50m.
QUOTE(celciuz @ Jul 9 2011, 11:04 PM)
If shoot at something far away, I wonder how to determine the focus -.-... let's see when I'm free enough I will do it.
Why would it be difficult to determine focus? Can't you zoom to check?

SOS:
http://photorumors.com/2011/07/07/bringing...e-kills-pixels/Below is a very interesting video from Kodak describing the way film and digital cameras capture light. Around the 8:00 min mark you can hear a thought-provoking statement that when you bring your camera on a plane over 20,000 feet, the gamma rays can actually fry some of the pixels on the sensor. This is why all major manufacturers are shipping cameras by sea and this is considered an industry secret because of the fear of lawsuits.

Thanks for the info. Will view the video later. Anyway, how do you explain Nikon DSLR cameras in space used by NASA?
