'Snap'-instelling wijkt qua principe niet ver af van hyperfocaal instellen behalve het verschijnsel dat bij dat laatste oneindig inbegrepen is. Dat ben je bij reportage-achtige fotografie zelden nodig.
Of je het nou anataal of digiloog doet, de kunst bij dit soort slechtlichtactiviteit is niet zozeer het instellen van je camera (da's een formaliteit) maar meer het inschatten waar je onderwerpen zullen verschijnen en daar je snode plannen op aanpassen.
Bij heupschieten is AF weinig bruikbaar, je moet zoveel mogelijk uit waarneming en koele berekening doen. Oefenen kun je zelfs met een digitale compact als die handinstelbaar is. Gewoon maar proberen en bij oefenruns ruis voor lief nemen, als je de techniek van het inschatten en afvuren eenmaal onder de knie hebt ga je voorzichtig eens met je filmpjestuig spelen.

Kijk voor een stille EOS ook eens naar de modelletjes als de 50(E) of de 5. Beide razendrappe reflexen en uitermate stil. Ze gaan op de advertentjessites voor afbraakprijzen.

Op Amazon.com (mirror) zijn de specificaties van de Canon EOS 40D uitgelekt. Gezien de naam en de prijs van de camera gaat het om de langverwachte opvolger van de 30D. De officiële introductie wordt maandag verwacht.

Verbeteringen zijn onder andere de stap van een 8,2 naar een 10,1 megapixel sensor met automatische schoonmaak-stand en een groter (drie inch) lcd-scherm met verbeterde kleurweergave. Een van de meest opvallende nieuwe features is de mogelijkheid om een live preview op het scherm te krijgen, iets wat vroeger onmogelijk was voor spiegelreflexen, maar waar men tegenwoordig steeds vaker omheen weet te werken.

De 40D kan langer en sneller schieten in continu-stand: de buffer kan met 6,5 frames per seconde vol worden geschoten en ongeveer 75 jpeg-beelden vasthouden voor hij vol zit. Het autofocus-mechanisme is volgens de specificaties ook helemaal vernieuwd.

Het nieuwe model is iets groter en zwaarder dan de 30D. De prijs op Amazon voor alleen de body ligt op 1300 dollar, ongeveer 300 dollar meer dan zijn voorganger op dit moment kost. Foto's van het ontwerp zijn helaas nog niet uitgelekt, maar binnenkort zouden we meer moeten weten.

EF-S 18-55mm f3.5-5.6 IS Lens

Developed in response to consumer demand for a high-quality yet affordable optically image stabilized lens, the Canon EF-S 18-55mm f3.5-5.6 IS standard zoom lens adds a phenomenally flexible lens to the EOS 40D SLR shooter's imaging arsenal. While it features the wide-angle to mid-range zoom flexibility of its non-IS predecessor, this new EF-S 18-55mm f3.5-5.6 IS lens offers the significant advantage of a true lens-shift image stabilization system that yields up to a full four stops of image-shake correction.

The higher performance provided by Canon's lens shift IS system (compared with the in-camera sensor shift type offered in some competitive SLRs) includes the ability to optimize the lens performance for specific shooting situations such as low-light, long-zoom, or movement while shooting (or virtually any combination of the three). What's more, the shooter can see the image stabilization effect in the viewfinder. As the image already appears steady, more accurate framing and composition is possible, the AF point can be placed more precisely, and the photographer can concentrate on the optimal shot more comfortably.

Het is slimmer om eerst te sparen voor een nieuw objctief dan voor een camera. De wet van de fotografie schrijft nl dat camera's in prijs omlaag gaan, maar dat objectieven duurder worden....mits je al een cam hebt natuurlijk

Volgensmij gaat het hier niet om een echte live preview. Ik heb in de reacties op T.net gelezen dat de preview in zwart/wit is en dat je geen foto kan maken tijdens de preview. Waardeloze feature dus, wat sowieso imo niet echt nodig is voor een dSLR.

Als je dit consequent doorvoert, koop je dus pas een cam als je oude kapot is. Er is immers altijd wel een lensje dat je nog niet hebt.
