So if you take that same lens (say one made for full frame) and then crop out the bits that APS or 4/3 sees and the scale it up to those pixel densities, instead of getting more clarity you just get more mush. The EOS EF300mm is one such example. Looks great full frame but starts to soften noticeably when using only the portion projected on 4/3 sensor sizes.<br /><br />I've tried this on both film and a friends 5D with similar results.<br /><br />However as its effectively a 600mm on my 4/3 camera it probably looks better than a 300 + a x2 teleconverter.obakesanhttps://www.blogger.com/profile/13743339737847465926noreply@blogger.comtag:blogger.com,1999:blog-1709537690528523236.post-2995241164718697802013-11-25T03:07:39.303+10:002013-11-25T03:07:39.303+10:00not being an engineer I never spend much time revi...not being an engineer I never spend much time reviewing these types of charts. It is interesting though. If I follow what i think to be their point, almost all modern cameras are limited by their lenses. Is that correct? <br />I'm confused though by the different ratings for the same lens in different mounts. Your 30mm in 4/3 vs APS for instance. It could be that the lens construction is different however i kinda doubt it. I also see dramatically different results for a Canon mount vs a Nikon mountCharles Maclauchlanhttps://www.blogger.com/profile/16371804975922943864noreply@blogger.comtag:blogger.com,1999:blog-1709537690528523236.post-27870137302219308172013-11-25T00:08:43.202+10:002013-11-25T00:08:43.202+10:00I can't claim I understand the way DxO test th...I can't claim I understand the way DxO test the lenses, but the Sigma 30mm f2.8 can resolve much more than 8MP. On my 16MP NEX-6, the resolving power of the lens is unbelievable given the price point. It puts most expensive lenses to shame.Lens Bubblehttps://www.blogger.com/profile/06445561503570800312noreply@blogger.com
