Zvonimir Tosic: Interestingly, Pentax representative said that they have already experimented with sensor shift technology to achieve same goal as this, now advertised by Olympus (and Hassy in the past). But, Pentax admits, the result is a large size dataset, plenty of megapickles, but the quality of the picture does not improve.
So instead of delivering that — which obviously is not difficult — they would rather focus how to make native resolution even better.

Which is interesting, as it better sheds light on what Olympus really wants to achieve: a perception that their small cameras (which are indeed limited by sensor size and performance worse that others), are also competitors when it comes to large image sizes.

Zvonimir- that is fine, but the problem is that Olympus already proved that they were able to get notable gains in resolution data. The fact that the smaller sensor Olympus is using out resolves in this mode the Pentax K-3 is quite remarkable.

Nobody is saying what Pentax should do or not in order to increase resolution.You quoted the claim from Pentax and the claim as far as Olympus is concerned *has been proven wrong* already because Olympus *did achieve* better resolution.

Of course Olympus's solution has limitations, but it seems they are working to expand the operating window of this solution. So basically it doesn't matter what Pentax said regarding getting more data- Olympus *proved* they are getting more data with this approach. It's not theory.

I am not changing the terms of the question. This was what I said "... and Pentax had several axis IBIS long before Olympus." and what carver was daring me to provide evidence for- and I did.
Moreover, Pentax had it before the E-3 anyway, if we want to follow what you are saying.

i hope you know that Valentine day is for straight couples :))

Naveed- there are many customs that are celebrated today that have evolved.- for example Christmas is not when Jesus was born, and was done after a pagan rite to other Gods, but it was the way the church saw they could more easily convert others- so we have it now.

ST. Valentines is at this point, more about celebrating love between those special ones, and that includes gays. Gays certainly do not need your permission :-)

Lassoni - fate!
Howabout- the question was about my claim that Pentax had multi-axis IBIS long before Olympus. So yes, my answer proved the point.

Moreover, the Pentax mechanism other than gyros for measuring pitch & yaw is all that is necessary for the sensor to correct for those (see the Sony 5 axis ibis discussion elsewhere). The Olympus sensor also doe snot rotate along x & y even though Olympus 3d rendering animations show it doing so.

Raist3d: Wow, that is weird! So basically without a sony lens with IOS, you really don't have 5-axis IBIS? Man, they should explain this better. Software corrections vs optical are never better than the real optical ones.

I think it's innovative that they can use a lens OIS to finish the axes of IBIS but they should come lean on this. If I am using a prime lens (usually no OIS), then we don't have true 5-axis IBIS.

Thanks Ken- part of the issue is that Olympus own marketing materials show videos with a 3d rendering where their sensor clearly tilts. Then dpreview asked Sony with this expectation in mind, possibly misinterpreting what they were saying.

This effectively means Sony is just correcting the same way- just sometimes use the sensor in full to do it, or the lens OIS.

Thanks again.

ZeneticX: OMFG those are fracking huge lenses.... ops sorry wrong topic

@Barry - I wasn't talking about these lenses when I said that. I was talking about some past APS-C mount zooms. The only thing I was saying is I wonder if there was any collaboration with someone else for them or it's 100% Pentax/Ricoh, given Pentax has collaborated with other lens manufacturers in the past.

I am not expecting anyone to prove that they are NOT other designs. Yes, the onus is on me making the claim and all I am saying is I wonder if it's possible *because* Pentax has done so in the past. So my statement isn't unreasonable, I am not claiming any certainty here, just wondered a possibility.

These are two different things.

I was thinking of the Tokina collaboration, yes. As far as I know, some lenses are Tokina tweaked designs, not all Pentax designs. I remember the discussion where one of the Pentax Gold star lenses looked way too similar to a Tokina design- that doesn't suggest Pentax designed it- at least the core aspect of it.

I only say this because I know some companies have had some of their lenses designed by others (not all, just some). Basically I am not saying Pentax can't do it, but was wondering if as well, Pentax hired someone to do them. But yeah, Pentax certainly has know how- and so does Ricoh.

I wonder how much of these lenses are Pentax designs (or Ricoh designs) vs sub-contracting someone else.

Pentax had it first, and it had tilt. The E-3 body doesn't have tilt. Neither does the E-5 body. The OMD EM-5 is the first to have the 5-axis IBIS.

I would imagine you can turn "image stabilization" off. But I am not sure you can selectively turn it off vs the mechanical aspect of the IBIS.

caver3d- you can look at the Pentax 100D - the first one back in December 2006. Look at the 2nd page of features. That's X, Y and Z axis. Nobody else had something like this until Olympus further developed with the OMD EM-5 pretty much. And sure, the Olympus covers more axes, but doesn't take away the Pentax anti-shake is multi-axis, including tilt.

Prove it? Pentax had axis tilt. So you have up/down and axis tilt (look it up). That's multi axial IBIS. You can even shift the sensor and tilt when setting the camera on a tripod to adjust the composition a little bit - as an option- so you don't have to move the camera on the tripod! The K-5 came long before the OMD EM5, and this capability existed in Pentax SDLR's before the K-5.

Rich- I wouldn't say Pentax "brings nothing to the table" either though. I mean, their K-3 and other cameras capable of turning the AA filter on/off (the actual results, not that it really has an AA filter) is actually pretty innovative, and Pentax had several axis IBIS long before Olympus.

Zvonimir- sorry but this is a weird thing to say considering the 40 MP mode clearly provides for more resolution, even without color moire artifacts, than the nominal 16 MP resolution.

I don't understand why you mention all that with clear evidence already to the contrary.

Commander, recon reports fracking huge lenses with actual visual contact... the cyclone got hold of big lenses and they are coming our way. I suggest we start to plot an FLT jump outside of the Nebula now...

Man, Fuji knows their stuff. That's all I have to say. Glad to see they are introducing also as options some slightly slower but much smaller lenses. That new XF35 looks so rad.
