Adam: “I would be grateful if you checked out some of my latest black and white work! http://www.adamthirtle.com/tagged/bwpage”
Ben: “I mentioned that I’m running a 2-day workshop for photographers to try out all the latest Olympus OM-D gear, in West Cork, Ireland. It runs during the weekend of the Baltimore Wooden Boat and Seafood festivals, May 24-25.
Following a request, I’m now offering a one-day option now as well. People may come for the Saturday only and the fee is £90.
I’ll have OM-D E-M1s, E-M10s and E-M5s, and all the top Olympus primes and zooms, also Sigma m4/3 lenses and a couple of the new Manfrotto tripods. The program includes a boat trip, to photograph boats under sail and the coastal landscape and sea-life; a pass for the castle, whose roof terrace gives the best view across the harbour; a hosted visit to an exhibition of superb local photography; and plenty of time for photography and to enjoy the bustle of the festival. It promises to be a great weekend.
The cost for the two-day workshop is €215, and Olympus are giving everyone a €60 cash-back voucher for OM-D/PEN camera or lens purchases.

Hah. GH4 makes 20/1.7 much more useful, but actually worse with the Sigma. Panasonic proprietary lens database in action.
Not the same size/weight/aperture…
PL 25 all the way 😉
was that mostly an example of how autofocus works with those 2 lenses on those cameras? And yeah in some shots the GH4 had more detail. Please explain your motivation and your findings?
More stuff about camera Jesus??
I’m sorry, but that is kind of a useless video.
Well that really encourages people to share anything for your benefit. What would you do if you had one?
It’s useless because it doesn’t reflect the way anybody I know actually uses their camera.
The video is very helpful actually, it shows the improvements in auto focus in video mode, and what can you expect from the camera. GH3 was better than GH2 regarding AF in video mode, and now GH4 is not yet perfect but is better than it was GH3. So the comparison is very helpful. I thank that guy for posting it.
It doesn’t actually show much, and what it does show is likely inaccurate. The way the 20 focused on the GH3? Just sitting there out of focus. Yes it does that sometimes, but it is intermittent. Are we supposed to assume that this intermittent issue does’t show up on the GH4? Ever? It doesn’t show up on the GH3 all the time. But we have a tiny sample size, and a casually performed test. What valid conclusions can we draw? And the Sigma focused faster on the GH3. Are we supposed to draw conclusions from that simple size of one casually performed test? Peevee a few posts below this did. Not only did he draw conclusions from that non-controlled, singular sample-sized experiment, but he was able to determine the cause of this performance disparity. I can just imagine him going to DPR and posting comments about “what he has seen with Panasonic’s proprietary lens database”. A casual test like this, with a sample size of 1, will tell us nothing. That is why this video was useless.
But if you haven’t done this test yourself then you have less than one observation which makes your comment less than useless. Making an inference from some data doesn’t stop anyone from updating their ideas later with more information. But the kind of anonymous troll attitude which doesn’t add any new information, disparages those who do something positive, and misrepresents the multi testing done as “1” is not helpful at all. Step up please.
Your opinion is useless, the video is very helpful!
My friend, this site is not about useful for us, it’s about useful for them, the corporations. They pay some losers to make a video, or write an article, or take some pics (well, that is actually out of date) and the rest is essentially free publicity.
M43 is an ailing system, this expensive GH4 is not going to turn that around, but they try hard.
MIRROLESS and M43 is the FUTURE, open your eyes !
FF will become slowly a niche market as medium format is, yes for advanced pros but a niche !
So is your comment.
So, the “proof is in the printing”…I use prints as my guideline as to whether I need to upgrade for better IQ. So far, any camera above 8MP, carefully used, seems to be more than adequate! “The proof isn’t in the pixel-peeping”!
gh4 af is fantastic
Is it just me or is there no actual solid proof in this video? Seems to me it’s totally random which camera/lens combination has the fastest AF. Though I’m not surprised to find the Lumix 20mm ƒ1.7 being horribly slow, haha! It’s a great lens but AF has always been it’s weakness.
Very slow indeed with both of the cameras. Sometimes gh3 did not focus at all? .. and sometimes gh4 was slower than gh3..weird? But IQ seems to be good.
Manual focusing is my choice with video.
Panasonic, it is called OSPDAF. Get on with the times!
