هنوز جانشینش معرفی نشده تولیدش متوقف شد ؟ d90 هم که جایگزینش معلوم نشده !

فکر کنم دیگه کسی با وجود D3100 نمیاد D5000 بخره، تنها دلیل میتونه LCD چرخان باشه.

کداک سنسور 29 مگاپیکسلی فول فریم خود از نوع CCD را معرفی کرد.

Kodak 29MP CCD sensor (KAI-29050)

Kodak announced a new 29MP full frame (35mm) CCD sensor. The KAI-29050 sensor is “the highest resolution CCD image sensor based on Interline Transfer technology”.

Highlights of the new sensor:

* features a true electronic (or global) shutter
* has a “plug-and-play” design for easy implementation
* 5.5-micron pixel
* supports up to 4 images per second
* 2x to 4x increase in light sensitivity compared to a standard Bayer color sensor

در متن خبر چیزی به چشمم نخورد که این سنسور کجا قرار است استفاده شود, اما امیدوارم (البته امید واهی است) که کداک آن را روی بدنه ای از برند خودش استفاده کند و ترجیحا ً با F-mount نیکون

دوربین فول فریم Kodak DCS Pro 14n محصول سال 2002 را احتمالا ً دیده باشید , هنوز هم طراحی اش به نظرم قشنگ و جالب است :

نیم رخ عضلانی که بی شباهت به تنه درخت نیست :biggrin:

بیشتر به نظر میاد مربوط به leica m10 باشه biggrin.png

فکر نکنم. لایکا از سنسور های اختصاصی شده استفاده می کند. بدلیل نبودن آینه در لایکا ها فاصله ی لنز با سنسور در لایکا ام بسیار نزدیکتر است. و این باعث می شود اشعه های نور با زاویه بسیار زیاد به سطح سنسور بخود. این باعث خطا می شود. یک راه حل می تواند استفاده از میکرو لنز ها در مقابل هر پیکسل باشد. که خطا را جبران کند. که البته آرایش این میکرو لنز ها اختصاصی برای لایکا باید باشد. کاردی که در M8 و M9 انجام شد. فکر نکنم این سنسور در همین حالت در لایکا ام قابل استفاده باشد. مگر اینکه سنسور را اختصاصی برای سری آم تغییر دهند.

البته کداک با تولید اختصاصی سنسور برای کارخانجات دوربین سازی مشکلی ندارد. در حال حاضر سه سنسور اختصاصی برای لایکا ساخته است. یک برای M8 و M9 و S2

پیش بینی های تام هوگان برای سال 2011

http://www.bythom.com/2011predictions.htm

* بصورت کلی در مورد اغلب برندها نظر داده , اما طبق معمول در مورد نیکون بصورت ریزتر و با ذکر جزییات بیشتر

(البته خاطرتان هست که بعضی از این موارد را برای سال 2010 پیش بینی کرده بود که محقق نشده بود, جالبه که به روی خودش هم نمی آورد :biggrin: )

خلاصه موارد :

D4 (though possibly D4h/D4x combo instead)
D800
D400
D7000
D5100
D3100
CP8000 (mirrorless)

و شرح آنها :

# D800: announced by end of March 2011.

* D700-type body, new Nikon FX high resolution sensor fabbed by Sony
* 18-24mp
* 4-5fps
* 1080P/24/25/30, 720P/24/25/30/60
* 100% viewfinder
* EN-EL15
* MB-D12 grip
* Yes, it's still coming. At Nikon speed (didn't anyone at Nikon ever watch Star Trek? Impulse Drive is the slow speed; we want engineering at Warp Speed ;~)



# D400: announced late in the year (August or later). The real question is what changes from a D300s?

* The D7000 16mp sensor, but with faster frame rates (both still and video)
* A new focus sensor, likely a derivative of the D4's
* 1080P/24/25/30, 720P/24/25/30/60
* Hard core pro body (more gasketing, probably integrated grip)
* Integrated GPS?
* EN-EL15 battery?
* Or, here's the alternative rumor: 24mp Nikon/Sony DX (yes DX) sensor in the D300s body with the D7000 metering and autofocus. This alternative doesn't make sense to me because it is literally at the limit of discernible resolution returns. Moreover, virtually all of Nikon's DX lenses will come up short in resolution, meaning we'd need another cycle of DX lenses. Makes sense from the "we'll make things that force them to buy again new" standpoint, but makes no sense at all when examined from a practical standpoint. Moreover, this would be the end of the line for DX as far as I'm concerned. Final note: if 24mp DX is the D400 alternative chosen, then the D800 probably won't appear in 2011. Nikon would be very confused trying to market a high megapixel D400, D800, and D4 at the same time. Thus, I'm sticking with 16mp, more hard core pro, as outlined above.



# D5100: a necessary update of the D5000, probably coming in the first quarter

* 14mp Nikon sensor
* D5000-like body and controls, but with the D3100 sensor
* EN-EL14



# D4: announced by August 2011

* new Nikon 18mp sensor with at least D3-like capability, maybe better
* completely new AF system
* better metering system (upgraded from D7000)
* Hard core video features (perhaps even 1080P/60)
* Integrated GPS
* USB 3.0
* Updated UDMA specs
* Big question: D4h and D4x, or D4 only? The high-megapixel FX sensor rumors swirling around Sony include a Nikon variant. The question is whether Nikon has moved up the pro "studio" camera to be introduced with the pro "performance" camera again (last time that happened was the D1h/D1x intro). I think the odds are good that they could, as the only real engineering difference is the sensor, and the sensor appears to be ready. Still, there's a big potential pileup in terms of marketing differentiation if Nikon pulls out all the stops (D400, D800, D4h, D4x). I can't see them doing more than three of those choices in one year, and even that is expecting them to be aggressive. I expect at most two high megapixel announcements (D4, D800).

# Coolerpix: Yes, finally a larger sensor Coolpix. And it turns out to be the missing mirrorless camera the executives have been talking about. Should be launched by February, certainly within first four months of year.

* Larger sensor, all Nikon, but it's not as big as DX. That means:
* New lens system (call it MX for now), which means a 28-105mm equivalent, a wide angle prime, a 50mm prime equivalent, a 70-300mm or 80-400mm equivalent, maybe a superzoom equivalent
* Video capability as per D3100/D5100
* EN-EL16
* So why is Nikon saying they reinvented the camera? I have two predictions here: unique optional EVF display (head mount) and a modest amount of user programmability. Wow, I don't believe I just wrote that. But yes, this is a camera you're going to interact with differently than ever before. Unfortunately, that's feeling a bit like the Coolpix with projector idea to me, but I'll keep my fingers crossed.
* This is not a m4/3, NEX, or NX competitor, as it turns out. Well, it is in the sense that it is a small, mirrorless camera with interchangeable lenses. But Nikon seems to be shooting low in the market. Compact camera consumer low. That means very small size, even with some big focal length ranges. But it also means a small sensor and everything that brings to the table. I have to really wonder if Nikon got this one right. The things I do know about it seem like they're swinging at a user who doesn't exist. Again, Coolpix projector feeling...




# Nikkors: Some of the missing Nikkors are no longer missing. By the end of 2011, the remaining missing Nikkors will all be here:

* A 80-400mm f/4-5.6 replacement, with AF-S and a new optical design.
* A 70-200mm f/4 addition.
* A long Micro-Nikkor: may not be 200mm. Nikon may try to kill two birds with one stone again by making it 180mm and faster than f/4.
* 50mm f/1.2G. Why? I don't know.
* A 24-70mm replacement. I'm guessing 24-105mm f/2.8 VR, and announced with the D4

تنها چیزی که در پیش بینی های تام هوگان برایم ناراحت کننده است, این است که باتری EN-EL3e گویا دیگر کاربردی نخواهد داشت .... رفتیم زاپاس هم گرفتیم براش :(

شایعه جدید سایت nikonrumors پیرامون تولید سه لنز جدید نیکون هست. ۲۸mm f۱.۴ AF-S, ۵۰mm f۱.۲ AF-S و ۸۰-۴۰۰ VR II .منبع خبر هم یک سایت آسیایی هست که پیشتر، معرفی‌ الیمپوس E-PL۱s رو به درستی‌ پیش بینی‌ کرده بوده.

پیشبینی‌ قیمت ۵۰mm f۱.۲ نیکون هم حدود ۴۰۰۰$ آمریکا هست!
