The Mcon is very light. Its weight is barely tangible. That, it being short and very easy to attach to the lens, and the ability to still auto focus are advantages compared to an extension tube. The lens I have I can use it with is the m.Zuiko 40-150. I haven't tried anything other that the full 150 when using it. The distance from subject you can focus in is very narrow. So you are going to to have to be about .5 of a metre away. To get to the conclusion first: The kit lens is equal, if not superior than the 150 + Mcon on a static subject. If your subject is likely to fly away if you get close, then the kit lens is no go and the 150 + Mcon will probably allow you to not disturb an insect. EPL1. All images taken at f/6.3 at ISO 200 with camera on a gorrilapod. Daylight through window. m.zuiko 14-42 Mark 1 at 42 in its natural state. I've adjusted clarity in Lightroom to get the best result I could for each image. The colour difference in the coin is how it came out, I didn't adjust the colour. There's purple issues with the coin Mcon+150 - the box should be blue. I took the images at the same time of day and light conditions so I'm not sure why one has more shadow. 150+Mcon: 14-42: (a 20p is 21.4mm across) 150+Mcon: 14-42: So it seems to me that the only reason to use the MCON P01 with the 40-150 lens is if you can't get as very close to the subject as you need to for the best close up result with the kit lens.
