Nikon D610 DX Image Area Clarification

[Photo_Adventure]

I have some questions related to DX image area option in D610. Questions as below.

1. Is this DX image area option can be treat like a sRAW (Small RAW) option in Canon camera? As at FX mode is 24M and DX mode is only 10MB which will save a lot of SD card storage.

2. If I select DX image area mode (1.5x) with 24-70mm F2.8 lens (I understand that the image square area will become smaller via view finder). So, I wonder will it multiply the F2.8 x 1.5 = F4.2 as well? Will the 24-70mm F2.8 lens will become 36-105mm F4.2 lens? The reason behind is to have smaller RAW file size.

Thx ya.

Hi
I can answer the 2nd question.

2. If I select DX image area mode (1.5x) with 24-70mm F2.8 lens (I understand that the image square area will become smaller via view finder).

>>By selecting DX image area mode it is like
using a smaller portion of the entire image.
It is similar to cropping photos.
Also you will have less pixels to use/work on.

Instead of cropping them in Post Processing,the camera crops for you if you select DX image area mode.
and it uses less megapixels thereby the file size is smaller.

So, I wonder will it multiply the F2.8 x 1.5 = F4.2 as well?

>> I don`t think so.
The Aperture/Fstop will remain the same unless one pairs with a teleconverter on it.
Teleconverters affects the Exposure triangle.
So..it is not F2.8 x 1.5

its going to be
F2.8 x 1.4 TC =
F2.8 x 1.7 TC =
F2.8 x 2 TC =

Note However: 24-70mm is not compatible with any Teleconverters.Do not try.

The Fstop will remain at the max for 24-70mm at f/2.8,
however the field of view is smaller now.
You may see the EXIF if you taken a shot in selected DX mode it will remain the true focal length between 24 to 70mm.

Will the 24-70mm F2.8 lens will become 36-105mm F4.2 lens? The reason behind is to have smaller RAW file size.

Yes but not at f4.2 instead a max f2.8
[B]>>By selecting DX image area mode one can extend the focal range.

It does.
1)The File size will be smaller.
2)The Field of view will be smaller like one crops a picture.
It does bring the image closer.I would say its a Digital Zoom.
3) The EXIF will remain the true focal length of the lens used
4) Buffer fill rate in Dx mode will not fill up that fast .

Hi thx for details info, this really help. This is a good discussion from technical stand point.

YouTube info below did mentioned under DX mode, the Aperture will be multiply by 1.5x as well. For example the F2.8 in Full Frame mode will become F2.8 x 1.5 = F4.2 in DX mode. So, any D610 users would like to comments on this? Or any have use this DX image area with D610, any feedback so far? Thx.

Btw, where to download the EXIF software?

Actually the DX image area option on D610 does not work that way as in to be treated like a small-sized RAW. It is because the image captured on D610 using DX crop format will be cropped, so you will lose the angle of view as well.

Choosing DX Mode on your D610, it will also increase the continuous shooting rate as stated by Nikon.
"When "DX format (24x16)" is selected, the continuous shooting rate is faster than when "FX format (36x24)" or "5:4 (30x24)" is selected, allowing for more shots with each burst of continuous shooting." source: http://nikonasia-en.custhelp.com/app...dGJFLTJ2am0%3D

As for the aperture, it will remain the same even if you choose DX image area on the D610. It is not calculated that way where the f/no. multiply 1.5 crop. Only the focal length has to be multiplied by 1.5. So, f/2.8 will still be f/2.8.

Thx all for clarification, now I can used mine D610 and select DX image area to gain an extra reach in focal length. TQ
