  1. Sony RX10 V oficjalnie. Aparat z superzoomem zyskuje procesor AI i baterię z serii Alpha

    Rynek aparatów kompaktowych z niewymienną optyką i mniejszymi matrycami niemal całkowicie umarł, wyparty przez zaawansowane smartfony. Istnieje jednak jedna nisza, w której tradycyjna konstrukcja wciąż wygrywa z telefonami: aparaty typu superzoom, oferujące gigantyczne zbliżenia optyczne, fizycznie nieosiągalne dla urządzeń mieszczących się w kieszeni.

    Sony doskonale o tym wie i po latach oczekiwań odświeża swoją flagową linię, prezentując model Sony RX10 V. Piąta generacja tego wszechstronnego kombajnu fotograficznego naprawia największe wady poprzednika, implementując nowoczesny układ autofokusa sterowany przez sztuczną inteligencję oraz znacznie wydajniejsze zasilanie.

    Dla zaawansowanych amatorów fotografii przyrodniczej, sportowej i podróżniczej to jedna z najważniejszych premier roku – pozwala zrezygnować z noszenia ciężkiego plecaka pełnego drogich obiektywów.

    Jeden obiektyw do wszystkiego i optyka ZEISS

    Konstrukcyjnym fundamentem Sony RX10 V pozostaje sprawdzony, niezwykle jasny obiektyw ZEISS Vario-Sonnar T o ekwiwalencie ogniskowych 24–600 mm* oraz zmiennym świetle F2.4–4.0. Tak ogromny, 25-krotny zoom optyczny pozwala na jednoczesne rejestrowanie szerokich kadrów krajobrazowych oraz ekstremalnych zbliżeń dzikiej przyrody czy zawodników na boisku.

    Inżynierowie poprawili również możliwości pracy z bliska, co docenią miłośnicy makrofotografii:

    • Minimalna odległość ostrzenia przy szerokim kącie (24 mm) wynosi teraz zaledwie 3 centymetry.
    • W trybie telemakro, przy maksymalnej ogniskowej 600 mm, aparat potrafi ustawić ostrość już z odległości 72 centymetrów.

    Sercem urządzenia jest warstwowa matryca Exmor RS CMOS typu 1,0″ o rozdzielczości 20,1 megapiksela, zintegrowana z najnowszym procesorem BIONZ XR. Ten duet gwarantuje znacznie lepszą plastykę obrazu, wierniejsze odwzorowanie odcieni skóry oraz skuteczniejszą redukcję szumów podczas pracy w trudnych warunkach oświetleniowych.

    Autofokus z procesorem AI i 30 klatek na sekundę

    Najważniejsza zmiana zaszła w systemie ustawiania ostrości. Sony zaimplementowało dedykowany układ przetwarzania AI, znany z najnowszych bezlusterkowców z serii Alpha. System rozpoznawania obiektów w czasie rzeczywistym potrafi autonomicznie identyfikować i śledzić ludzi, zwierzęta, ptaki, owady, a także pojazdy takie jak samochody, pociągi i samoloty. Algorytmy bez problemu utrzymują ostrość na człowieku, nawet gdy ten jest odwrócony tyłem, porusza się chaotycznie lub nosi kask i okulary przeciwsłoneczne.

    W połączeniu z migawką elektroniczną aparat staje się demonem szybkości. RX10 V pozwala na fotografowanie seryjne z prędkością do 30 kl./s przy pełnym wsparciu śledzenia AF/AE oraz całkowitym wyeliminowaniu zaciemnień (blackoutów) w wizjerze. Nowa funkcja Continuous Shooting Speed Boost pozwala na zmianę prędkości serii w dowolnym momencie bez przerywania pracy.

    Wideo 4K w 120 klatkach i ergonomia z serii Alpha

    Sony RX10 V to także pełnoprawne narzędzie do filmowania. Urządzenie wspiera teraz natywne nagrywanie w jakości 4K przy 120 kl./s, co pozwala na uzyskanie płynnego, 5-krotnego zwolnienia tempa w postprodukcji. Twórcy wideo otrzymali do dyspozycji profile kolorów S-Cinetone oraz S-Log3 wraz z możliwością wgrywania własnych tablic LUT (do 16 plików .cube). Nowością jest funkcja automatycznego kadrowania AI, która podczas nagrywania ze statywu samoczynnie docina obraz 4K, imitując płynny ruch operatora podążającego za postacią.

    Wyraźne zmiany zaszły w samej konstrukcji korpusu. Trzymając aparat w dłoni, łatwo pomylić go z profesjonalnymi bezlusterkowcami:

    • Zastosowano krystalicznie czysty wizjer OLED Quad-VGA o rozdzielczości 3,68 mln punktów i dużym powiększeniu 0,78x.
    • Rozdzielczość odchylanego ekranu LCD wzrosła do 1,62 mln punktów.
    • Wygodny, ośmiokierunkowy dżojstik ułatwia szybki wybór punktów AF podczas patrzenia przez wizjer.

    Największą bolączką poprzednich generacji był mały akumulator. Sony rozwiązało ten problem, implementując do RX10 V ogniwo NP-FZ100 (z serii Z), stosowane w pełnoklatkowych aparatach. Przełożyło się to na 50-procentowy wzrost wydajności, pozwalając na wykonanie około 630 zdjęć na jednym ładowaniu. Całość zamknięto w uszczelnianej obudowie odpornej na pył i wilgoć, wyposażonej w szybkie Wi-Fi, port USB-C z funkcją streamingu 4K oraz pełne wsparcie dla nowej aplikacji Creators’ App.

  2. My workhorse Sony RX10 M4 camera, used for many years, stopped working during the New Zealand trip. So it was time for an upgrade: a Sony α6700, which I paired with a Tamron 18-300mm F/3.5-6.3 Di III-A VC VXD lens. Still getting used to it, but so far, it has performed to expectations. Now to exceed expectations. :-)

  4. Lens-Artists Challenge #324: In the Details

    Note: This is the entry for the Challenge that I had intended to make last week, before life got in the way. I had the text all worked out, pretty much, so I’ve left that as it is. I had adapted the text for last week’s post, so there may be some overlap. I hope that you don’t mind. 

    Something a little different for the Lens-Artists Challenge this week. Instead of a specific theme, Patti of pilotfishblog has announced her ‘In The Details‘ challenge. Quite simply, Patti asked us to choose a subject, any subject, and take a series of photos, getting closer and closer each time and focusing on detail. ‘Vary your shots’ of the subject, she says, and ‘change your perspective’ each time. Then ‘post three photos of [each] subject’.

    After last week’s stymied attempt we headed out this past Monday. The day didn’t quite go according to plan, but the weather was lovely and I made the best of it. The camera I chose for this project is the Pentax X70, a 12MP camera from 2009. It’s what they used to call a ‘bridge’ camera — it looks like an SLR but the lens is fixed and it has features closer to those of a compact camera. What appealed to me for this project is the well publicised (at the time) 24x ‘superzoom’. This means the lens has a range of 26mm at its widest to a whopping 624mm. 

     One thing that the Pentax X70 doesn’t have is a thread on the lens, so if I want to use it with a neutral density filter for some Intentional Camera Movement I’m going to have to hold the filter in front of the camera while I’m waving it around. In fact, I had a little practise with this camera the day before and discovered that the camera’s response with the neutral density filter is not that good. I’m really not sure why but a lot of the images came out really dark, even at the neutral density filter’s lowest setting. 

    Anyhow, it was a lovely sunny day and we headed out to the nearby seaside town of Barra. I already had my subject in mind, and as usual it’s a bit of a cheat on the theme, ‘In the Details’. My first image is a broad ICM view of the beach, which includes my intended target, I hope that you can see it? Because the variable ND filter is a little dodgy with this camera, the slowest shutter speed that I could achieve was about 1/50s, but a good fast sideways sweep seemed to do the trick.

    Then we moved towards my ‘subject’, which is situated on a long pier which forms the entry to the port of Aveiro. The pier is about 1,5km long and it’s a lovely walk, especially on a pleasant sunny day. There are always people jogging the length of the pier, and this day there were many fishermen (actually, exclusively men) lining the ‘port side’ of the pier, where the water is much calmer compared to the sea-facing side.

    About mid-way along the pier is a tall bright orange structure. I’m really not sure what this is for and it was only added about 10 years ago. However, it does feature a door for access, so certainly something goes on in there. And here we find my first detail. Some aspiring street artist has drawn this lovely ghost-like figure, which perfectly fills the door. It’s been there for a few years now, and as you can see other visitors have put stickers on the door, and generally messed with the image.

    In fact there’s another ‘ghost’ in Barra, near a set of steps in a residential part of the town at the top end of the beach. I’m hoping that the artist created a series of these around the town, and I’m always on the lookout for more.

    However,  this was not the detail that I came to Barra for, so we headed further along the pier. At the end of the pier is a small automated lighthouse, which I imagine is there to stop boats running into it at night. There’s actually another little lighthouse on the pier at the other side of the entrance, but that is always battered by heavy waves and I’m not sure if access is even allowed. This pier is getting closer to my subject, and if you look closely you can actually see my ‘In The Details’ subject. 

    Just beyond the lighthouse, forming the end if the pier, is a pile of concrete shapes that support the entrance to the Port of Aveiro. These fit really well together and form a secure barrier around which the pier was built. You can actually climb over these rocks, and people do (I have done this myself. Not recommended) either to get a view of the ships coming into port, or for the fishing (which is a big thing on this pier). And there, on these concrete shapes, are the details that we have come to see: smiley, happy faces. I’m not sure when these were added, but I’ve been here in Portugal for 20-odd years and they’ve always been there. 

    I did have another subject in mind, a half-built and abandoned house near the water behind Barra. I spotted this from the car as we passed over the bridge approaching Barra, but when I reached the house it wasn’t as wonderful as I had imagined. Nevertheless,  I thought that you might like to see the photographs that I took of this. In the first image, the lamp post is not distorted by the wide angle of the Pentax X70, it’s actually been pushed over.

    Later this week I hope to prepare a post on this week’s theme, ‘Gratitude’, but we shall see. It’s not proving to be easy. Themes for the Lens-Artists Challenge are posted each Saturday at 12:00 noon EST (which is 4pm, GMT) and anyone who wants to take part can post their images during the week. If you want to know more about the Challenge, details can be found here, and entries can be found on the WordPress reader using the tag ‘Lens-Artists’.

  5. Lens-Artists Challenge #324: In the Details (Part One)

    I had great plans for this week’s Lens-Artists Challenge, great plans. But a combination of factors meant that we were unable to get out, despite the nice autumn weather on Monday and Tuesday. The rest of the week hasn’t lived up to expectations either. So what I’m going to do is post three images that I grabbed earlier in the week and then, (hopefully) when we go out next Monday I’ll make an attempt at the Challenge I had in mind. 

    This week, instead of a theme, Patti of pilotfishblog announced an ‘In The Details‘ challenge. Quite simply, Patti asked us to choose a subject, any subject, and take a series of photos, getting closer and closer each time until we were  focusing on details. ‘Vary your shots’ of the subject, she says, and ‘change your perspective’ each time. Then ‘post three photos of [each] subject’.

    The camera I have chosen for this project is the Pentax X70, a 12MP camera from 2009. It’s what they used to call a ‘bridge’ camera — it looks like an SLR but the lens is fixed and it has features closer to those of a point and shoot camera. What appealed to me for this project is the well publicised (at the time) 24x ‘superzoom’. This means the lens has a range from 26mm at its widest to a whopping 624mm. 

    The first cloudscape was at the camera’s widest angle, 26mm, and the third image was at near maximum zoom. I didn’t fill the frame with the moon, although this camera is certainly capable of doing so, because these are all hand-held grabs and at such magnification it was difficult to keep the camera steady, as you can see from the framing.

    So I hope you will all excuse this little bit of fun. The plan for next Monday is to go out and hopefully get the shots I was aiming for this week. It’ll be a busy time Lens-Artists wise, since by then Patti will have delivered the theme for the next Lens-Artists Challenge. 

    Themes for the Challenge are posted each Saturday at 12:00 noon EST (which is 4pm, GMT) and anyone who wants to take part can post their images during the week.

  6. Yay, picked #comet #12P #PonsBrooks out of super-bad skies over #Bochum, Germany, with a #superzoom camera - on a tripod with a few seconds exposure - an hour ago. According to cobs.si/obs/comet/484/ the total coma magnitude is ~5.9 right now. 11x70 binoculars, normally quite good with comets, showed exactly nothing in this "sky" with a naked-eye limiting magnitude of ~2.3 - but the €300 camera saved the day, err, evening. 12P could get another 2.5 mag. = a factor 10 brighter: yes, please ...!
