I spent a night in Finnature‘s forest feeder studio in Liminka. There are LED lights so you are able to shoot portrait pics all the night. Facilities are very good, I can recommend the place.
All pics are non cropped, ISO 5000-6400, 1/60-1/100 sec. All the E-M1X pics were shot with bird tracking AF – I must say it is very accurate focusing to bird’s head and eye. In these kind of circumstances silent shutter is also a must.
Gear: E-M1X + M.Zuiko 300/4 and E-M1 Mark III + M.Zuiko 40-150/2.8 + MC-14.
Here is a straight forward Sandisk Extreme SD memory card speed comparison test with four different types of cards and three OMD bodies.
E-M1 Mark III has one UHS II compatible slot (Slot 1). Both slots of E-M1X are UHS II compatible.
All bodies were tested with M.Zuiko 25/1.2, mechanical shutter, sequential mode 10 frames/second (PEN-F Sequential H, others sequential L), 1/1000 s, f/1.2, ISO 400, manual focusing.
I put the camera on tripod and started shooting. When shooting slowed down, I stopped shooting and started the stopwatch. When the camera buffer was empty I stopped the stopwatch and counted the frames on memory card.
The results of the test 1 are on Table 1.
In practice there seems to be no difference between 90 Mb/s, 95 Mb/s and 170 Mb/s UHS I cards. UHS II is very fast in UHS II compatible slots: with 10 f/s the camera buffer gets never full and you can shoot continuously if necessary.
E-M1X slot 2 seems to be faster than slot 1 with each card. This is interesting.
I also tested with 15 frames/second (sequential H) to find the limits. Results are on Table 2.
