Fullformat vs µ43: Comparison of Bokeh

July 27, 2013  •  Leave a Comment

Today some technical aspects - and how it influences the image. The item of the day is "Bokeh". Never heard? Bokeh is the expression of the parts of the photo which are blurred because they are not sharp. It´s Japanese...

When I started the hear and read more about photography "Bokeh" comes more and more into my mind: I found out that I played with it since I started to photo.... Recently I got an idea for a shot in our garden. We have some  Joseph´s Lilies in our garden. And we have a walnut tree where we have installed a LED tube with different color. I started shooting with my new 45mm Macro Lens getting some really nice pictures...

When I started the shooting I thought: It might be interesting to compare this pictures with the Canon 100mm f2.8 USM-L lens with the full format sensor. Just by the laws of optics there will be an influence: Less depth of sharpness and more blur. But how does this looks?

Canon EOS 5DMkIII with EF 100mm f/2.8L Macro IS USM @ ISO 200, f 2.8, 1/125

The Results looks dramatic to me. Yes it makes more fun to use the full format sensor... but the result for 43 Isn´t bad, or? 


Ad the end of the evening, when it became even more dark I added another shot to the series which I like as well:

Canon EOS 5DmkIII with Canon EF 28-300mm f/3.5-5.6L IS @ ISO 4000, 300mm, f5.6, 1/250s Canon EOS 5D MkII with Canon EF 28-300mm f/3.5-5.6L IS @ ISO 4000, f5.6, 1/250s, 300mm


For me it is amazing to see what the longer lens offers in term of bokeh - even if the maximum aperture is only 5.6.
