The following opinions have been automatically translated with Microsoft Translator. | Tamron SP 45mm f/1.8 Di VC USD Pros: Construction, Price, Stabilization, Brightness Cons: Autofocus too Uncertain Opinion: Nothing to say about many aspects of this lens (Solidity, construction, Price, Stabilization, Brightness). I sold the 50mm Canon F1.4 because I was wrong a lot of focus. But I don't know how much the situation has really improved. If I buy a super bright fixed lens it is because with low light I want to make it take the field and see that it solves my problems. Here, on the other hand, with low light often the AF is useless because it focuses even for 2 seconds before hooking the subject (so seizing the moment often becomes a utopia). This goes to affect a bit all the positive aspects that the lens would have (hold down the shutter button, but seeing that the SLR (Canon 5D4) does not shoot because it is laboriously trying to focus, makes me very angry). I even say that AF seems uncertain and not very reactive even during the day in the sun, which for me is inconceivable. I don't want to totally reject it because I want to use it more often (even if I have owned it for 2 years) and maybe try to start a better feeling. sent on December 17, 2021 |
 | Samyang 14mm f/2.8 IF ED UMC Aspherical Pros: Price, lightness and portability, good quality. Cons: Manual focus ring distances approximate day, inability to tighten filters Opinion: Then I too have succumbed to the temptation and I bought this lente.rnVi tell you now that you will have to take the time to learn how to use it initially, even though I thought that my experience was more than enough to "tame the goal," I missed a lots of focused (so avoid buying it behind for a trip or an urgency, because you will cause problems) .rnDiciamo that day with so much light and knowing the hyperfocal by stopping work out pretty well, but with little light and forced to shoot wide open, free hand there is the risk of making mistakes all focused even applying the hyperfocal because unfortunately the ring distances focus is not accurate but only indicativa.rnDetto this I end I solved well enough by enlarging the maximum on the display of my reflex point of focus and focheggiando manually until you get a perfect MF (though taking becomes more cumbersome and takes away the time, but onlyso you will avoid having to throw a photo) .rnLa positive surprise however was that, despite the optical informs EXIF ??data and aperture value appear in only one zero, putting in aperture priority, the camera based on the calculation of He manages to calculate the correct shutter speed for proper exposure. This somewhat 'aiuta.rnAltra consideration, initially the photos seemed poorer quality than my usual shots, because enlarging shell almost immediately. Ragionandoci but I understood that my 18Mpixel forced to describe an angle of view of 14 mm are obviously less dense than a picture taken in 24millimetri or more. So is normale.rnTutto added so the lens is worth every euro spent, as long as we take the time to fully understand its mechanisms working key and accept leaving the "inconvenience" that this lens (no filters, manual Focus, no EXIF ??data). sent on January 13, 2016 |
