Sony a99 - mirror and mirrorless comparisons
5 months ago

Hello,

I took some (very boring) shots at ISO 100 and ISO 6400 with and without the mirror using the same light condition. The focus point is the Lion logo "Peugeot".

First of all, the scene was not well lit (voluntarily). For comparable shots with and without mirror, I shot in manual mode, and the exposure was locked to be identical (same ISO, same f number, same exposure time).

All shots at ISO 100 were shot at: f/1.4 and 6s

mirror, ISO 100, 6s, f/1.4

mirrorless, ISO 100, 6s, f/1.4

This exposure of "mirror, ISO 100, 6s, f/1.4" was matched to that of "mirrorless, ISO 100, 6s, f/1.4" by using the exposure slider (+0.5) in ACR >>> mirror match, ISO 100, 6s, f/1.4, +0.5

All shots at ISO 6400 were shot at: f/1.4 and 1/13s

mirror, ISO 6400, 1/13s, f/1.4

mirrorless, ISO 6400, 1/13s, f/1.4

This exposure of "mirror, ISO 6400, 1/13s, f/1.4" was matched to that of "mirrorless, ISO 6400, 1/13s, f/1.4" by using the exposure slider (+0.5) in ACR >>> mirror match, ISO 6400, 1/3s, f/1.4, +0.5

At ISO 6400, the matched photo shows shows relatively more "pattern noise" than that found for the mirrorless photo.

Cheers,

moimoi

Photography is about time, space, expression, and - ultimately - capturing light. This formula may sound easy, but actually capturing the "ideal" photograph is far more complex to accomplish as our own perceptions and responses vary according to each individual. Photography is inherently driven by human subjectivity, but the general feeling is that a superb photograph is widely appreciated, as it commonly depicts a striking and universal concept. I believe this process should be sought by many of us, who deeply enjoy capturing and sharing photographs that embrace life and depict what we are.
