This is a shootout of the FF and MFT ‘nifty fifty’ lens. I used my much loved 50mm Sigma ART f1.4 lens on the Nikon, and the Olympus 25mm (which is 50mm ‘full frame equivalent) on my E-M1. Although both of these lenses were acquired by me because of their fast speed, for studio work its normal to shoot stopped down because throwing a background out of focus is not an issue with a plain paper background, and it also ensures focusing isn’t as critical, so all of the model is in focus.
3 x light stand
4 x 8′ x 4′ black board for flagging light
3 x Elinchrom Digital SEE studio strobes (unmodified)
Nikon D750 with Sigma 50mm f1.4 ART Lens
Olympus OMD E-M1 Olympus f1.2 lens
The model is Tsui Kim
E-M1, Olympus 25mm f1.2 @ISO200, f11, 1/200s (studio strobe setting not recorded)
D750, Sigma 50mm f1.4 ART @ISO200, f8, 1/200s (studio strobe setting not recorded)
In a studio environment the weight saving of the MFT system is perhaps not such a big advantage, but on the other hand the extra shallow depth of field of the full frame system is cancelled out because we are shooting stopped down. So unless the photos are being enlarged really big, this one really is a dead heat in my view.
