I think it is better to just have two lens caps glued together ! A Velcro in a bag won't resist torsion well enough. Especially if it is hanging perpendicular to the bag like the picture shows

Well that behavior (returning to the defaults camera settings) is the same with all the camera apps and is very annoying : it is so for instance with the timelapse movies app : I have the AFLock on the back button, but I have to reset it to the shutter release if I want to be able to focus while using an app. The same goes for using a scene mode : unless I put the AFL back to the shutter release, I can't focus my pictures if I have chosen the portrait scene mode. What a hassle.

On Manfrotto unveils Digital Director for iPad Air article (46 comments in total)

The question is how do you fix that thing to your tripod/head : there is nothing about it. I'm sure that you will need additional parts and then the Cindy will go up.

NB : all my cameras are already able to talk to the iPad via WIFI, so I'm rather interested into the hardware.. Although of course for the moment what you can do with the software produced by the cameras manufacturers is nit so performant.

Weia: Where can I find more about diffraction limits and sensor size? Fourthirds, APSc and full frame. Especially in macro.

@ Weia

Ooops.. I hadn't seen you were doing mainly macro. Macro is a particular case. With general photography, many variables can be ignored (some tends to 0 other to infinite and thus they can be ignored). Macro is a whole other story given the much smaller distance involved.. I'm not qualified enough to say more about it.

@ nerd2

Diffraction is dependant of aperture, length of the wave and of the circle of confusion. By convention, the circle of confusion of MFT is 2x smaller than that of FF, because for the same print size you need twice the magnification. Also those circle of confusion are convention linked to film times. With the modern high res sensors like the D810 or A7r, the diffraction strikes earlier due to the denser pixel pitch, you are right in this.

The larger the difference between the wave length and the aperture the less diffraction you see. At wide aperture there is no diffraction because the difference between the two is important. The smaller the aperture, the nearer the two becomes, the more interference you get, aka the more diffraction will blurr your picture.

Here is a link to Wikipedia concerning diffraction :
a) in general :
http://en.wikipedia.org/wiki/Diffraction#Diffraction_of_light
b) for imaging devices :

For FF the sweet spot of lenses is usually around F8 and F11.
For MFT it is around F4 and F5.6. After that diffraction takes a toll, so unless you need the deeper DOF it is better to avoid using smaller aperture.
For more, aka mathematic formula you could may be make a search on Wikipedia .. For the sweet spots of individual lenses look at the MTF charts you can usually find in lenses reviews (for instance at Photozone.de, at DXOmark.com, at SRLgear.com, at Lenstip.com etc.)

Thanks DPREVIEW team for offering a written interview rather than a video. I do really appreciate.

obsolescence: The 40MP high res mode is the main feature that would make me want to buy an OMD camera -- I could fix the artifacts of moving objects by patching in upsized segments from outtakes in post. What I really need for architecture and landscape is a 17mm equiv. shift or tilt-shift lens, preferably one that's not too expensive (like Canon's is). I'll bet Samyang could build one.

@ fmian
Because it is all done in one single click ! Because it allows you to get non converging vertical without fussing around in software.
Because at near distance (studio work on product photography) you can still get everything in focus etc.. Etc..

In reply to:

ABM Barry: How do we process RAW Hi res. I downloaded the latest version of Adobe dng converter 8.8. However, none of my Adobe programs can handle the 40,000kb files and the 102,000kb have no chance?

The supplied olympus disc also states that it can't handle them, ... it states: "FILES TO LARGE"

I can't imagine the reviewers actually tested this out or they would have mentioned this problem? Or if they did, why wasn't it brought to our attention?

I probably would have put off purchase until it was sorted!

Also the shooting menue option is only jpeg or RAW+jpeg, can't seem to capture RAW only? not an option? (I don't shoot jpeg, far too limiting)

The logical question is: "What have I missed"

@Valiant Thor

The last version of Olympus Viewer is able to develop normal raws only, not the HiRes ones. You need the Olympus import Plugin for Photoshop if you want to be able to develop the HiRes raws.
That was untill the last version of Adobe camera raw was issued. Now, the problem is solved for all raws and HiRes files, if you have CS6 or CC.

The limit may be that you need a PC with a processor which can handle 64 bits. I seem to remember that the Photoshop plugin offered by Olympus on their CD states that it won't work on a 32bits machine.

Andrei Todea: This guy doesn't have a clue about photography. I just love how he measures image stabilization in steps instead of stops. What an idiot!

Don't you think it could just be a language problem ? May be he isn't an anglophone speaker.. Not everyone has English has his native language

This is not fair for non anglophones !

@ Richard Butler : thanks for taking notice of my comment. But reading speed being much faster than speaking and hearing speed, a video will never be as effective as a written text.. Hiwever, i understand that writing takes time, probably more time than creating a video ?
Anyway, i'm sure it takes you a lot of effort too.. So i just wanted you to hear the voice of those that prefer reading to seeing videos.

I hate video : especially this one. That guy seems to have something interesting to say about focusing, but he is speaking so fast that it is not understandable for persons like me who aren't native English speakers.

Plus it takes way too many time to look at it.

Give me the same thing in a text illustrated with a few pictures.. That is all what is needed.

Great post ! I agree with most things you said, owned a Canon 5Dc then also several Olympus MFT up to the E-M5. Updated to a Canon 6D but now also own a Sony A7r and regret that update to the 6D which I don't use anymore.

What the EOSm misses more than lenses (that could come) is an integrated EVF. I know there is an optional one, but from my experience with the E-P3 I find it to be an annoyance. It makes the camera cumbersome to store and you have to add about 200$ if you want to use one.

In reply to:

(unknown member): always surprised about the pricing, 3699 dollar retail and 3999 euro. 3999 euro is about 4580 dollar us.
Look like a great cam for a specific market.

US prices never include VAT. In order to make a fair comparison, you have to take the about 20% VAT in account. Divide 4580$ by 1.2 and then prices are similar : 3816$. Well, even a little lower.

Jurka: Expensive for such small and noisy sensor. Every, even cheapest Canon, has better iso and dr range and details.

Well you picked the worst example of all : I own a Canon 6 D plus an E-M5 and a Sony A7r. The E-M5 is offering as much DR as the Canon 6 D. Pick a camera using a Sony sensor if you want yo be convincing : a Nikon or a Sony alpha for instance

brycesteiner: High Resolution mode question: I'm not quite understanding why the D810 is so pixelated when it comes to the colored half circle images at the bottom of the samples. I understand the colors may not be accurate because of the bayer filter but does that result in the low resolution too?

On the D810, you get moire when there is too much fine details. This is due to the color array on the sensor. Olympus is using the first four shots to get all three colors for a single pixel instead of using interpolation. (Sensor typically get 1 green, one red, one green and one blue pixel. By moving the sensor four times of exactly one pixel, the E-M5 can get all the color information for each pixel and thus it doesn't need to interpolate and avoids moire. The second series of four shots moved by half a pixel are adding to the resolution, still keeping the same color trick.

prossi: Can you update the spec table with the EM1 and take out the EM10? Nobody cares about how it compares to that lower tier model.

The manufacturer and retailers care : they want the E-M10 owners to upgrade to an E-M5II.. They don't expect so many users would exchange their E-M1 for an E-M5II.
But yes, DPreview could add a 4th column for the E-M1 !

prossi: Finally a paintbrush and sponge static sample wedge that that can compete the apsc and ff from sony and nikon! It was getting depressing listening to all the praise of 4/3 cameras and be confronted with such crappy IQ for landscaping.

Just pray that there is absolutely no wind, nor moving waters. Forgot about sea shots...
