Nikon F2 focusing screen question

Hello
Im new to the forum and I've been dealing with an issue regarding my F2 focus screen.
For the F2, Nikon made several models of focusing screens.

I recently lost my focus screen. When I went to the camera shop (in Paris) to buy a new one they only had de G4 model.
As you can see below, taken from mir.com I found out the G4 was specially made for 300mm lens.

I own a 50mm lens and my question is if by using the G4 focus screen with my lens, will it make my photos be out of focus?

Thanks!

Type G (G1, G2, G3, G4)
Nikon description: Clear Fresnel field with extra-bright 12mm-diameter microprism focussing spot for use in poor light. Four models correspond to lenses with different focal lengths:

• G1 for fisheye
• G2 for wideangles
• G3 for 50f/1.2 and 300f/2.8
• G4 for 300f/2.8

The microprism spot is optimized for the longer/slower lenses - which often caused a black-out with the K and J type screens. I suspect that if you can see the image, you should be fine. The surrounding fresnel screen should be usable.

This is one of the few screens that I do not have.

Try Ebay for a better suited screen.
