On article Photokina 2016: Olympus E-M1 Mark II overview video (279 comments in total)
In reply to:

Gazeomon: For Olympus users the EM1 II maybe a tempting camera to upgrade to. The stats and the camera features look very good, but I don't see any compelling reason to switch from any APSC system. The size advantage is negligible and the image quality maybe comparable (at best). Olympus's 'pro' lens offerings although very good quality are not exactly compact either. I would consider Olympus if I would not be committed any other system.

If you take a Canon 80D, Samyang(Bower) 8mm fisheye, Canon EF-S 10-18 (16mm FF equi. UWA rectilinear), 18-55, 55-250, Canon 100-400 II
you get 7.8 pounds. The reach at the long end is virtually the same since the 80D allows a bit more cropping (compared to the mark ii), reducing the Oly tele advantage to only about 10% more. Given the better sharpness at the long end of the Canon, I would guess they actually give similar results at 400mm.

that's the future. Not only software renting from the cloud (Adobe etc.), but now also hardware renting, it will die whenever companies decide.

photonius: As far as I recall, the cover shot with the pyramids is not the shot shown above. It was the three main pyramids all lined up behind each other, which is not possible physically.

hmm somehow i thought it was a different cover.

Hmm, I guess they forgot about the basic principles of photography. Who wants extra flare reflecting of shiny golden inside surfaces....

hmm, while nicely done, I expected something else from the title, i.e. the same view of the skyline in time-lapse over three years. These are just cuts and edits, all could be done over a very short time.

gag...

... and now, how about a pain by numbers camera with touchscreen to select what picture you want. No actual landscape needed.

photonius: As pointed out by SickVodka, it's not really a Swiss company. To summarise findings of many people: The Swiss person (of the two person shareholding company) is involved in several other companies, the location in Baar is not surprisingly in the canton with the lowest taxes in Switzerland. Many other international companies locate their tax headquarters there. The Foreign Investor of this company is Polish, and is the owner of foto-tip. This was actually one of the key companies to bring the Samyang lenses to Europe, the first European Web site for Samyang was Polish. So, it looks like the IRIX brand is simply a high class product from Samyang. Not sure if Samyang themselves will come out with this product, or if this is really the brainchild of the Polish entrepreneur to make improved Samyang products. Samyang still sells their lenses to other resellers for rebranding. But Samyang has now established its own reputation, maybe now branching out to higher level (like Lexus vs Toyota)

Thanks for this extra tidbit Astrotripper. Yes, indeed, the polish Samyang web site disappeared. And foto-tip has a clearance sale of the Samyang lenses (for good?).

photonius: Dear Canon
In your shift to "upmarket", don't forget the Rebel owners. I don't want a heavier upmarket model, I will always stay with Rebels for weight. But I sure would appreciate (and maybe buy a new body) if you would not cripple the Rebels in software, why not give them MFA, timers, and other things that can be implemented with little extra cost. And a GPS for travel...

@ nekrosoft13 m43 didn't exist when I bought into (are rather, reentered) the Canon system. Since then, I have been following the m43. Considering the whole lens system, and other points have not convinced me to change yet.

@ nekrosoft. Well, they still could add weight :-)
Seriously, the same as now, i.e. dual pixel sensors, better viewfinder, higher frame rate, more AF points. Of course,
I'd still buy these extra features at higher price, if the weight/size is not more than the lighter rebels.

A travel camera with no GPS? sony, mobile phones have it....

Giuseppe Fallica: If Sony is able to fill 22mp inside a small 1/2.6 "sensor, this means that today it could fit 220MP inside a full frame (which is exactly ten times larger), using the same technology

@photominion.
You could bin the pixels at 3x3 for a 24mp image which might have even less noise than 24mp sensor. you could use the 220mp oversampling to correct for lens aberrations without loss of resolution (e.g. geometric distortion), there are possibilities.

My pinhole from 1495 still works ;-) Just kidding.

The test looks very much like the Hoya HD tests.... Any comparison between these two?

deep7: "..with an equivalent maximum aperture of F8 and F12.6 on the 200mm and 800mm equivalent ends". One of the true advantages of m4/3 over larger formats - particularly at very long focal lengths, the extra depth of field is very welcome!

Sorry, I hadn't realized you were quoting, and I made too many logical jumps. The point was that this factor 2 focal advantage of m43 over FF in terms of reach doesn't hold up so well with todays sensors, after all, what counts is how many pixels you get over your subject. m43 has not increased its pixel density as much as FF. But given diffraction limits, photosites will have a limited small size. There is a minimal size for photosites irrespective of sensor size. larger sensors just can have higher MPs. Think of it like the Nikon FF bodies that take DX crop lenses, and just crop the image on the sensor. Of course, not everybody has a 50 or 40 MP FF body (yet), but a 500mm lens on a 51MP body does the same job as a 400mm lens on a 20 Mp m43 (and olympus is still stuck at 16mp). So, comparing to a 800mm starts to be misleading.

Actually, you are wrong. At this tele distances, you want to have maximum resolution for birds or whatever, and zoom in to 100%. Thus, you want to have your circle of confusion - for simplicity - defined as the size of your image sensor pixels. For a Panasonic Lumix DMC-GX8 (20MP), we have 3.3um. For a Canon 760D (crop, 24mp), we have 3.7um. And for a Canon 5DS (FF, 51MP), we have 4.1um. On dofmaster - using 400mm, f6.4, at 20 meters, we get a DOF of 9cm for a Coc of 3um, and 12cm for a Coc of 4um. So, the larger sensors have more DOF. And the m4/3 format does not have a 2x "reach" advantage over the a high res FF like the Canon, only about 1.25x. Still, it looks like a very tempting, interesting lens for that weight!

Boissez: Those 300mm shots are just... horrendous. What's the point of having 20MP+ cameras if you're going to strap on a coke bottle? Might as well go with a superzoom like the Panasonic FZ1000 instead.

The ship looks not to bad. The bad background is due to atmospheric distortions

In reply to:

AEY: Is this is true "Maximum aperture F3.5 - F6.4"
What is minimum aperture?

@cainn24,
thanks for the info. I had missed that they added an aperture in the hx50. hx20 and hx5 don't have one.
anyway, sounds promising if the lens was improved.
