Leaked Pentax NC-1 Mirrorless Photos? (Body w/ Two Lenses)

The previous Pentax "NC-1" mirrorless rumour has become more true. The "system" photos are leaked, there are one body plus two lenses:-



via the Mirrorless Rumors:-

http://www.mirrorlessrumors.com/hot-first-pictures-of-the-pentax-nc-mirrorless-system/

But with a crop factor of 5.6X to the 135 Full Frame and using the smallest P&S sensor for a DC of 1/2.33", what's the true meaning of this mirrorless ILDC system? :-o In fact, the IQ of such a mirrorless system will be no better than an ordinary DC and just worse to the more superior prosumers which use just a larger sensor, e.g., the Olympus XZ-1 and the Pana LX5, etc.! :-(

On the other hand, the NC-1 is the first Pentax interchangeable lens body which has a true video motion compression codec in H.264, which the current K-5 and K-r both lack, which is somehow a good news and start anyway, if it is to be true.

New Sony Full Frame CMOS Sensor - The "Super 35mm"



http://crews.tv/blog/2011/03/22/sony-fs-100-enters/

It is yet a rumour at this stage but it is very likely to be true and official announcement will come very soon.

Well, as it was previously observed, the E-mount is actually 135 full frame compatible!

The most important thing is that Sony now has a new 35mm "Super" CMOS sensor, which is specifically designed for Full HD video recording. And straight-forwardly, it should be able to take high quality still photos at the same time.

The good news and new hope to all those old Pentax K-mount users is that the new Sony FF sensor could possibly be used by Pentax in a coming Pentax FF model, but only if Pentax could get it and more so provided that Pentax is willing to make one!

Update (3-24): I have been mistaken, the "Super 35mm" is not 135 Full Frame format!

See the Sony brochure and we can see:-

I must have been dreaming for a Pentax FF for too loooong so that I could not see more about the facts! :-o ;-> Too bad.. :-(

The photos are yellow/orange casted as what *ist DS sometimes tends to be for its AWB and tendency. I still like the colour response of the Takumar more nevertheless, no matter for the original picture that has the cast or the post processed and colour corrected one. The FA77 is sharper (comparatively the Takumar is softer) and more contrasty, though, but whether one likes it or not would be subjective.

A 5000 fps Video Showing Mirror and Shutter Vibrations of a DSLR (The High-speed Nikon D3)



The D3 was put into high frame rate mode of 11 fps and shooting continuously.

Really amazing! Indeed, we can see vibrations and oscillations for both the mirror and shutter, for both lifted-up and down, opened and closed, respectively. But we can see that all the dampings are made to be good, the oscillations die down very quickly, which is the most valuable thing that we should appreciate, about the superior mechanical engineering by Nikon.

Update (3-23): Thanks to Blog readers Zebooka and Simon, we have also the K10D video. Just go to: http://unblockyoutube.co.uk and enter http://www.youtube.com/watch?v=4cJyKKnR5b8 into the link box to view, if you are just unable to see the blocked video.

PhotoZone DA 18-135 Test Results Will Not be Good (Very Possibly..)

http://forum.photozone.de/index.php?/topic/711-pentax-18-135mm/

See what Klaus, owner/reviewer/editor of the PZ commented and wrote "preliminarily", a few quotes:-

"I'm sort of disappointed. I expected more from a 700EUR lens."

"The centering quality is alright for such a lens. Such a complex lens is never really perfect, of course. The field curvature at 18mm is an issue and the borders/corners at 135mm are just soso. This would be Ok ... if the price tag was lower. "

"The data does not suggest this. The Tamron 18-270 is also superior." (Someone asked if the DA 18-135 any better than the Sigma 18-125 HSM.)

The most mysterious thing is that Klaus told us that he planned to publish the review till the first week of March. But now time is approaching fall March. What went wrong actually? What's going on? :-o

The Sony NEX-3 Discontinued (Official) and NEX-7 is Coming (Rumour)

As published in the Sony Japanese webpage, the NEX-3 has been discontinued:-

http://www.sony.jp/ichigan/products/NEX-3A/

As the NEX-3 was first marketed just back to May of 2010, the product life time of it is only 10 months.

Nevertheless, my NEX-3 has served me well as a compact APS-C camera, more so for a large sensor HD continuous focusing movie camera as well as an APS-C K-mount EVIL.

Anyway, it is rumoured that the NEX-7 is coming. And it should have a built-in EVF if the following rumour is true:-

http://photorumors.com/2011/03/16/sony-nex-7-to-be-released-soon-no-full-frame-nex-camera-in-sight/

Let's see what will happen soon, or not.

Japan Semiconductor/Imager Fabs and the Earthquake (and the End of the World, as It Could Be!)

I have seen people of the photo community have been worrying about the cease of production of the Sony (and Canon) sensors and imagers after the big earthquake. One of the readers at the Image Sensors World Blog has actually made an analysis and a nice summary on the situation. See the following location map of the major fabrication facilities in Japan:-

http://image-sensors-world.blogspot.com/2011/03/japan-fabs-and-earthquake.html



Btw, the Sony factories are all at the very southern part in the Japan main island and territory. But however, since now the radioactive particles have been flying in the sky all over Japan now and the emission has been increasing. This is somehow yet another disaster to Japan and actually to the Earth. As the half-life of those radioactive raw materials could be as short as 30 years. I think the soil of the Japanese main island would inevitably be polluted and the health of the people who live there are seriously endangered.

In fact, the Japanese government should allow the assistance from the US government for the cooling of their nuclear plants in the very beginning, which the US offered, but not only at the current stage, which could avoid this terrible disaster to happen. In fact, the foreign medias have started to doubt that the Japanese government had some secrets to hide which they just do not want to disclose these in the course of stopping the nuclear crisis if US is involved.

When one tragedy is happened one after another and the following one is more serious than the previous, this is really rather sad. Indeed the nuclear leakage is partially caused by human but not solely a natural disaster, which only triggered it. It has far more prolonged effect and more serious impacts even than the terrible earthquake and tsunami, which just happened "one-off". Sometime, we just have to sigh, stupid mankind is just the one who will destroy themselves at the end of the days when we or our predecessors will extinct eventually, just because of that we destroy the world and kill ourselves as a result! >:-(

Lastly, I just want to ask our buddies who have worried much just about the production of photo gear, what to worry about actually when the Earth will be destroyed and human cannot live on it anymore?! :-o Yes, the sky is falling! Yes, it is! +_+
