Nikon D500 crop factor

Hi,

I've procured a Nikon D500 recently. It's a nice camera. However, while using Nikon 300mm f/4 on it, I'm getting the same f/length i.e. 300mm; on DX format the crop factor should apply and I should get the f/length equivalent to 450mm. The exif also shows the same f/length.

What's wrong and where's it wrong?

Can I have some inputs please?

Welcome,your lens is still a 300mm that can not change,the D500 is capturing a smaller section of the image equal to a 450mm lens,not sure how the Exif reports on the D500 as i dont have one but it will be giving the field of view equal to a 450mm.

Thanks for your response. Ideally it should give, but it's not giving actually. I have checked other owners' photos also, all show the normal f/length reading.

It is a DX camera just like my D7100. I also have a D750 I have a 70-300 that is used on both cameras. The EXIF data on both cameras shows 300mm BUT the field of view on the D7100 is 450mm..

You post is not real clear. What exactly are you expecting it to show? The EXIF should show 300mm on your D500

Thanks for response. I am concerned for both f/length and exif. I am neither getting the f/length of 420mm in the field nor in the exif. Actually, I checked it with TC 1.4x and ideally I should get 300mmx1.4=420mmx1.5=630mm which is not witnessed in the field.

Thanks for response. I am concerned for both f/length and exif. On D300 I got the exact exif with FX lens ... I used 70-200 and at tele end it showed 280mm in exif and also I got that focal length (not in the lens but through the crop factor).

Here, I am neither getting the f/length of 420mm in the field nor in the exif. Actually, I checked it with TC 1.4x and ideally I should get 300mmx1.4=420mmx1.5=630mm which is not witnessed in the field.

Do you have a FX camera that you are comparing it to? I can tell you that my DX camera does not show the effective focal length. Both my FX and DX only show the focal length that the lens actually is. In this case both show that it is 300mm.

Yes you are right. But in the field the difference in the f/length i.e. the image is bigger and closer, should be witnessed. Isn't it?

Yes, d610

Shoot a photo using the same lens with both cameras. Make sure it is the same subject from the same place. Try to have a subject that will show some vertical lines so we can see the size good. Use the directions below to post them. This will preserve the EXIF details for us to see

Post both photos

Guidelines to adding a photo to your post.

1. Resize photo to 1000px on the long side.
2. Resolution set to 72ppi (Pixels Per Inch)


These guidelines will be good for viewing on a computer but will not be good for printing. This will help safeguard your copyright.

The focal length is the focal length and the EXIF data will reflect that regardless of the crop factor of the camera you are using. My 300mm lens will record as 300mm regardless if it's mounted to my D610, D750 or D500. The same image taken with both the D750 and the D500 using the same lens, however, will look different, with the D500 only capturing the center 44% of the D750 image - effectively as if I was using a 450mm lens on the full frame camera.

However, when you introduce a TC into the equation the EXIF data will reflect that. So yes, a 300mm + 1.4x TC will show as a 420mm lens.

If you really need to see the focal length after crop factor is taken in to account just upload to flickr and scroll through the exif data where the 35mm equivalent of your focal length will be shown.
I fail to understand why some users cannot get their heads around such a little thing as the crop factor on DX.

You are right. I am also concerned about the field output which I have to recheck. I will revert on this. Thanks.

The exif in Flickr is what it is actually without considering the crop factor. There I was wrong previously.

The DX function on crop factor is an extra gain for the wildlife photographers, so the heads keep going you know. ;)

Thanks a lot for your inputs.

If you take the time to look properly at your flickr pics you will see just the basic info is shown automaticaly.
There is also a caption (in blue lettering) which states SHOW EXIF.
If you click this and then scroll down through the data you will see where it also states focal Length (35mm equivalent).
(if you do a lot of pp this may be stripped off the info, if so upload another unedited or lightly edited pic and you will see that I am correct).

I don't know how he likes it, but it lives on my D500. Super sharp and super like - lighter than my 70-200mm f4. Perfect walkaround wildlife lens.
