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

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.

Can't find anything in the specs, but the previous models had no aperture, just a ND filter that dropped in when necessary. Makes actually sense, because at f6.4 one is already diffraction limited with such small pixel size, so one doesn't want to make it worse by stopping down an aperture.

photonius: Looks like a worthwhile upgrade to the HX20, because of the viewfinder, and it didn't gain weight! Only nit-picking is the no RAW. However, I presume the images are highly cooked, so that RAWs would have lots of issues, and probably Sony can't be bothered to provide a professional RAW converter for different computer platforms for such a consumer product.

My major issue would be: is the lens properly sealed this time? The HX20 has problems with getting dust on the sensor (yes, it's not a interchangeable lens camera, but it DOES get sensor dust. Had it twice within the warranty period, was fixed under warranty, but afterwards?). Probably because of the long zoom which causes quite some suction, and it seems there are no good seals in place. But this should be dealt with, the dust on a small sensor can be very visible and if that happens during travel, no way to fix it, it hurts all your pictures.

at cainn24. Well, what has been seen is in video mode, there is quite a bit of barrel distortion, which is not in still pictures.
So, I think it's not only noise reduction, but also CA, distortion, and vignetting correction that is applied. Obviously they implemented this all in their camera software. But I guess for a desktop computer, somebody has to actually sit down and write the RAW converter with all these optimisations (as option) as well (basically the lens profiles). I just think they can't be bothered to do this effort for a P&S. For a dSLR it's expected, so they do it. There may also be the issue of slow write to disk of large RAW format files.
I'm also not sure that third parties would bother to write a RAW converter module for such a camera.

tom1234567: I don't no why camera makers keep producing cameras with these
SMALL CRAPPY SENSORS

It's time the public were educated to what they are buying
Instead of being ripped off by ALL camera manufactures

In case you have not noticed, Sony also makes cameras with larger sensors, i.e. the RS models.
However, there is no avoiding the laws of physics for optics. Big sensors, big optics....
If you want a small camera with a good zoom range, this is the only way to go.
To be honest, my wife has a precursor, it's really nice. I often find myself grabbing it instead of my dSLR because it's so convenient. And the built in GPS works quite ok, why can't they get that into dSLRs if they can get it into such a little body.
So, in the end of the day, it's your choice what you want, no need to bash a product if you don't understand the reasoning behind it.
