Part 4 – Inside Museums


This is continuation of Part 3 – Harsh Lighting

Most of the photos are taken inside the Art Museum with decent natural indoor light, and very low light at the basement area.

For this I used,  Auto ISO, Auto Shutter Speed with Aperture priority mode. To my surprise the final images looked very similar.

High ISO of D810 was easily compensated by the better Image Stabilization from Pen-F. For e.g. I had to choose speed of when shooting at the focal length of 70mm.

D810 : 1/80sec, ISO 5000 and f/4

Pen-f : 1/25, ISO 1600 and f/2.8

I don’t have any clear favorite when printing at 8″ x 10″ size.

Theoretically ISO1600 should equal to ISO6400 at FF, but practically it’s not that way. When compare ISO1600 of Pen-F, with ISO1600, ISO400 and ISO5000 of D810, would say its somewhere in between ISO 3200 and ISO500.

Probably I might be able to get better image with D810 by manually identifying the right shutter speed and ISO combination with D810, but most likely I will use the Aperture Priority mode, as I prefer the camera to decide the appropriate shutter speed and ISO setting based on the zoom. I might just compensate the exposure based on preview but not likely to capture the ISO and shutter speed combo.

This is clear tie in terms of IQ, with both the combo for all practical purpose for indoor shots. As these shots will be handheld and not with a tripod and most likely with no flash.

But FF needs f/5.6 or f/8 to keep everything in focus, which forces even higher ISO. The same DoF can be achieved with f/2.8 f/4 with m4/3 sensor, I can keep the ISO even lower. This is where the lack of shallow DoF with m4/3 sensor has clear advantage.


My Preference : m4/3, mainly due to larger Depth of Field
