MILC fotoaparati / Nikon predstavio svoj novi Z sistem

« poslato: Avgust 24, 2018, 12:32:09 posle podne »

PDAF je na senzoru. Stabilizacija na senzoru.

Skuplji Z7 ima 46MP full frame CMOS BSI senzor. Znači sličan senzor kao u D850. Cijena $3399 u SAD-u.

Jeftiniji Z6 ima 24MP full frame CMOS BSI senzor. Ovo je novost naspram D750.

Oba aparata imaju magnezijsko kućišta.

Predstavili su za sada 3 objektiva. 50 1.8 i 35 F1.8 imaju dosta napredan dizajn za 1.8 objektive. Cijena je $599 za oba.
Ciljana je visoka oštrina po cijelom kadru već na F1.8. Neki govore i jako dobra transmisija svjetla.

35 F1.8 ima 11 elemenata u 9 grupa. 2 ED stakla i 3 asferična.

50 F1.8 ima 12 elemenata u 9 grupa. 2 asferična i 3 ED.

Tu je i zoom 24-70 F4.

Svi objektivi imaju kućište od magnezija.

Objektivi / Canon unveils stabilized EF 85mm F1.4L lens

« poslato: Septembar 01, 2017, 06:15:17 posle podne »

Canon has announced the EF 85mm F1.4L IS USM stabilized portrait prime. It's the company's first F1.4 offering at that focal length, joining its current EF 85mm F1.8 USM and EF 85mm F1.2L II USM lenses. The EF 85mm F1.4L provides up to four stops of stabilization, uses a nine-blade aperture and offers a dust and weather-resistant build.

In terms of the competition, the new EF 85mm F1.4L doesn't aim to beat the $1200 Sigma 85mm F1.4 Art on price: it will debut at $1600. At 950g / 33.5oz it does weigh significantly less than the Sigma, even with stabilization, but that may say more about the quite heavy 1130g / 39.9oz Art lens than it does about the Canon.

The Canon EF 85mm F1.4L IS USM is expected to ship in November.

DSLR fotoaparati / Glasina, Nikon D750

« poslato: Avgust 27, 2014, 12:10:53 posle podne »

Evo me dugo nije bilo ovdje, neke privatne obaveze i tako.

Nikon čini se puca opako po FF polju, praktički nema čega nema, a sada će doći još jedna kategorija aparata kako se čini, u neku ruku onaj pravi nasljednik D700.


Pa evo specifikacija o kojima se šuška:
- 24 MP
- 51 AF točaka
- 8 fps
- 91k RGB metering senzor

Cafe pcfoto / Koji smartphone kupiti?

« poslato: Januar 13, 2014, 06:55:07 posle podne »

Nadam se da se to može pitati na ovom forumu.

iako sam relativno mlad do nedavno nisam imao smartphone i onda sam se krajem godine počastio sa HTC Desire 500. Ono OK uređaj za nekoga ko prije nije imao smartphone, sve u svemu zadovoljan. Nego me sada odmah vuče da kupim bolji, pa me zanima što vi mislite bi li se isplatilo to prodati i za slične pare, naravno sko plan uspije, uzeti Desire 601.

DSLR fotoaparati / I oni su počeli... D5300 i D610

« poslato: Septembar 24, 2013, 05:48:11 posle podne »

Kako je Canon dugo vremena samo prepakirao postojeće modele sa sitnim ili nikakvim izmjenama čini se sa da isto radi Nikon tj. napraviti će sa D5300 i D610.

D5300

• 24MP

• 39 AF points

• EXPEED 4 (new)

• Built-in Wi-Fi (new)

• Built-in GPS (new)

D610

• Sensor: 24.3 MP (6016 x 4016 in L mode)

• ISO range: 100-6400

• AF: 39  focus point, 9 cross type, 33 point available at f/5.6

• Viewfinder coverage: 100%

• TTL exposure metering using 2,016-pixel RGB sensor

• Video recording capabilities: 1920 x 1080 30p/25p/24p

• LCD screen: 3.2", 921k dots

• Battery: EN-EL 15, using the same MB-D14 battery grip

• Dimension: 141 x 113 x 82 mm

• Update: the D610 will not have built-in GPS or Wi-Fi capabilities

Ako su glasine točne D5300 donosi neke sitnice, a D610 apsolutno ništa odnosno Nikon prodaje muda za bubrege.

MILC fotoaparati / Napokon Adobe podrška za Fuji X-Trans

« poslato: Februar 26, 2013, 01:07:25 posle podne »

I eto i ovo sada podržano od strane Adobe jer smatram da naspram klasičnog Bayera ima potencijal, a već sada ima Fujiev sustav bolji izbor objektiva nego NEX i rekao bi da je nakon m4/3 najpotpuniji mirrorless sustav. 

Adobe's Fujifilm X-Trans sensor processing tested

With the posting of ACR 7.4 and Lightroom 7.4 'release candidates' (RC), Adobe has updated its raw processing algorithms for Fujifilm's X-Trans sensor cameras, the X-Pro1, X-E1, X100s and X20. This move comes in response to months of online user requests for improved raw processing of the X-Pro1, Fujifilm's flagship mirrorless interchangeable lens model.

It is rare that Adobe's Camera Raw team revisits its demosaicing process for previously supported cameras, so we were excited to try out this latest version with some X-Pro1 raw files and compare results to the previous version of ACR, Capture One Pro 7 and Fujifilm's own in-camera conversion.

To provide some context, the vast majority of digital cameras ever made perceive color using what's known as a Bayer Color Filter Array, named after the late Kodak engineer Bryce Bayer. For its recent cameras, Fujifilm has developed its own color filter array pattern, which it calls X-Trans. The idea behind X-Trans is that its pattern repeats less often than the Bayer pattern, rendering redundant the low-pass filter that usually protects against moiré.

The disadvantage of creating a non-standard color filter array (especially one that took two years to develop the demosaicing algorithm for), is that third-party software makers have to do a lot more work to provide Raw support. Adobe was one of the first third-party software makers to provide Raw support for the Fujifilm X-Pro1, but the results often fell short of the standard set by the camera's own JPEG engine, in terms of rendering fine detail. So let's see what changes Adobe has made.

DSLR fotoaparati / Nikon press conference next week, very good chance of D7100 announcement Read m

« poslato: Februar 15, 2013, 08:25:54 posle podne »

Ukratko radi se o tome da vjerojatno D7100 dolazi prije nego su se mngi nadali i vrlo lako moguće sa novim 20MP Sony senzorom jer idući ili isti dan Sony predstavlja A58 sa 20MP(iako NR priča o 24MP) i 8 fps.

The exact announcement date for the US could be as early as Tuesday night (February 19th) but most likely everything will happen on Wednesday night.
...the only logical product for next week is the D7000 replacement (most likely called D7100 with 24MP sensor and 100-6400 ISO range).

DSLR fotoaparati / Sony SLT-A58 (α58), new 20MP APS-C sensor

« poslato: Februar 09, 2013, 08:34:30 pre podne »

http://photorumors.com/2013/02/08/the-upcoming-sony-a58-camera-will-have-a-new-20mp-aps-c-sensor/

Ovo sve skupa mi je jako zanimljivo. Sony koji trenutno u ponudi ima 16 i 24 MP APS-C dolazi sa nečim sasvim novim od 20MP, da li to znači i skok naprijed što se slike na visokom ISO-u(niski ISO ne spominjem jer Sony tu sa DR-om tradicionalno sada već dobar) tek terba vidjeti i pretpostavljam da će biti napredka ako je ovo nova generacija naspram 16 i 24MP senzora. Ostaje samo da vidimo zašto je to Nikon malo pričekao sa nasljednikom D7000 i hoće li on možda koristiti ovaj 20MP Sony senzor.

DSLR fotoaparati / Tokina Confirms Pentax Full-frame Under Development

« poslato: Februar 03, 2013, 04:59:40 posle podne »

A Tokina employee revealed to us today at CP+ that Tokina has renewed their discussions with Pentax about reviving their lens collaboration as of late last year.
According to the employee, Pentax is reportedly developing a full-frame camera (he claims that a prototype already exists). He stated that all lenses developed will be re-branded under the Pentax name as it had been done in the past.
Talks had previously stalled after the Ricoh takeover in 2011, but Pentax has requested that Tokina still show new lens designs for possible collaboration. However, no Tokina prototype lenses have been made for the Pentax full-frame yet, and no deals have been finalized.
Tokina is an independent lens manufacturer who has co-designed lenses with Pentax; those lenses have been branded under the Tokina and Pentax names. Though Tokina no longer markets many of these lenses, most of these co-designs are still sold under the Pentax name.

Nakon mnogo vremena koje su ovi objektivi bili izlagani kao prototipovi je Tokina odlučila na CP+ sajmu u Japanu objaviti službene specifikacije produkcijskih modela ovih objektiva. Vjerujem ako cijena bude korektna da će uslijediti tržišni uspjeh.

DSLR fotoaparati / Nikon unveils 24.1MP D5200

« poslato: Novembar 06, 2012, 08:07:02 pre podne »

A Nikon DX-format CMOS sensor with an effective pixel count of approximately 24.1-million pixels, extremely precise 39-point AF system, and a 2,016-pixel RGB sensor for superior basic performance
A full-scale entry-level model that enables flexible expression with a side-hinged vari-angle LCD monitor.

Komplet vijest na linku.


Moram reći da me iznenadilo što su stavili AF kao u D7000 i D600. Sam senzor nije onaj koji je u D3200 iako je slične veličine i pikselaže, ovaj je Sony za razliku onoga u D3200 koji je Nikon.

Tu se vidi vjerojatni razlog zašto Canon nije prešao 22MP kod FF senzora.
