Mm yeah I read that, the pancake is designed for smallness not image quality. I saw a second hand one for £100 in Cardiff but it had a whacking great lump of gunk in the middle of the lens just under the first element. Probably not going to affect the image, but it affected me.
I only want one lens for each niche. So I’ve got the standard kit, the 40-150 and the 70-300 (I’d not have got the 40-150 but it was £99 and I thought it would be plenty of zoom for wildlife.. may sell it not sure, having bought the 70-300 later), then the 35mm macro. I fancied the pancake for nice portable camera carrying but I’m just not sure if it’s worth it. Especially as I have an E600 not a 420 so that’s bigger to begin with. If it were faster then that would also be a draw but it’s only maybe a stop or a stop and a half better than the kit lens.
Only other thing now is the 9-18mm wide angle 🙂
