Nikon Releases Z 800mm at 1/3 Cost of Canon’s

[ericbowles]

Can you post some images demonstrating the "weird bokeh against foliage" please?

My experience is that bokeh against foliage often looks very weird even with normal optics, such as my EF 100-400mm. The reason for this particular weird bokeh usually has nothing to do with the optical construction, it's caused instead by heat haze, which can cause major deterioration in image quality when photographing mid-distance subjects on warm days.

Here are two images with the 800mm PF. PF lenses can have an odd bokeh from specular highlights, but it's a very limited case that I have only seen with photos of backlit shorebirds using the 500 PF. I have not tested the 800mm PF in that scenario.



Here is a 100% crop from the second image

Good images.

TBH for 1/3rd the cost & 1/2 the weight of the original EF 800mm I see this as a winner even when it's 1/3rd stop slower.

Canon has slowed down two noteable lenses by 1/3rd stop.

- 200/1.8 to 200/2.0

- 50/1.0 to 50/1.2

For the purpose of comparison here's the weight of select RF L & EF L the long lenses
