fuzzynormal Posted June 4, 2015 Share Posted June 4, 2015 Btw was it shot in 25p and slowed down even further in post or am I seeing things? It does give a feel to it though.50p slowed to 25p as needed. And I agree. I also do the 30p to 24p thing every once in awhile for a subtle motion effect.

Hanriverprod Posted October 9, 2016 Share Posted October 9, 2016 I was looking into this and found someone on reddit who says that there is a difference in autofocus speed between using native panasonic lenses vs olympus: "There is a difference in autofocus speed. Panasonic started to implement DFD(depth from defocus) technology and it is using Panasonic lens bokeh data to reduce hunting and increase af speed." - articrobot Someone else mentions in that thread: "Recently bought Olympus 40-150mm f4-5.6 (99€!) for my G7, in low light situations it hustles a bit more to get focus (AF) right, sometimes won't reach it at all." - carlakene https://www.reddit.com/r/PanasonicG7/comments/40ifgx/panasonic_g7_with_olympus_lenses/ Is this right? Olympus lenses are now slower on new Panasonic bodies? Quote Link to comment Share on other sites More sharing options...
TheRenaissanceMan Posted October 9, 2016 Share Posted October 9, 2016 Maybe empirically, but it's nothing you'd notice in actual shooting. Both brands focus very fast. Hanriverprod 1 Quote Link to comment Share on other sites More sharing options...

TheRenaissanceMan Posted October 9, 2016 Share Posted October 9, 2016 7 minutes ago, Hanriverprod said: Is the olympus clutch manual focus usable with follow focus? Yes, because it has hard stops, but they're still not as good as real manual lenses. Here's the deal: The Olympus primes have a distance scale and a very nice tactile feel, but the focus ring actually causes your focus point to jump between many discrete distances, not the smooth infinite spectrum of a proper manual focus lens. Therefore, you'll see your focus point "stutter" a bit as you turn it. This was improved from the 12mm to the 17mm, and again to the 12-40, but I haven't used any of them enough to say for sure whether or not it's noticeable in practical shooting situations.

tdonovic Posted October 9, 2016 Share Posted October 9, 2016 I've used all three pro zooms, and only use them. The 12-40 and the 7-14 are the best, they really do respond like a regular lens with a follow focus. The 40-150 is still usable, it gets a bit jumpy when focusing near infinity though Hanriverprod and TheRenaissanceMan 2 Quote Link to comment Share on other sites More sharing options...

JazzBox Posted October 9, 2016 Share Posted October 9, 2016 Olympus 12-40 f/2.8 and 40-150 f/2.8 are awesome on GH4 / G7. Hanriverprod 1 Quote Link to comment Share on other sites More sharing options...

(my panasonic lenses don't) They sure do! In fact, they remember your manual focus clutch position if you switch back to AF, too, so if you set your Mf ring to one point, switch to AF, then focus to a different point, simply moving the focus back to MF will snap your focus straight to that second point. Kind of interesting for when you need a quick pull. Chris Oh, jase and Hanriverprod 3 Quote Link to comment Share on other sites More sharing options...

jase Posted October 9, 2016 Share Posted October 9, 2016 Oly 12mm has those jumps when using the manual focus mode. The 17mm doesnt have any jumps - at least i dont notice them at all. 12mm is unusable for focus pulls.

TheRenaissanceMan Posted October 9, 2016 Share Posted October 9, 2016 That's why I've sold all my Oly primes besides the 45. Partnered with the 12-40, I don't think I'd want for anything more. Maybe a 17 for lightweight street/travel. JazzBox 1 Quote Link to comment Share on other sites More sharing options...
