Yongnuo YN600EX-RT

Pros: Price, quality and pro functions, Firmware upgradeable via USB, up to 200mm focal

Cons: Attack the slide improvable, missing the Italian manual white balance (read review)

Opinion: Well it built even if the attack on the sled tends to have a slight clearance (rotating) while being blocked. This rotation deflects the focus IR beam flash fire wrong, well, alignment with the field of view (just rotate during focusing to restore the alignment). impeccable exposure E-TTL and very uniform light on the entire screen. In close-ups there is a slight under-exposure of the lower horizontal zone (the light beam is raised because of the height of the parabola from the axis lens) and also using the included white panel, the "defect" is not totally resolved (but I think is a problem with all the flash). My individual (and many others as I read on the net) should be used with the white balance set to AWB because, using the flash mode, sporadically gives me picture with green or red dominant (mainly shooting in RAW) without a precise logic or condition. The beauty is that, in Camera RAW, known foto perfectly restorable in the original colors. The manual is in Chinese and English, although the latter is not perfectly translated, you can see the original of Canon 600. A note: I do not like that the SEL / SET button, the center of the wheel, is free to rotate .

Tamron 24-70mm f/2.8 Di VC USD

Pros: NN

Cons: NN

Opinion: I bought this lens used here on Juza.rnPurtroppo my specimen suffers from a strong front-focus and, with my EOS 1Ds Mark II, can not be calibrated by the AF menu.rnHo did test shots with a test chart detecting, at a distance of about 75 cm, a front focus of 3 cm (24mm focal af 2.8) up to a front focus of 6 mm at a focal length of 70mm af 2,8.rnSulla long distance (not to infinity) the front focus is 2/3 metri.rnAnche the manual focus "assisted" not c'azzecca.rnFare a portrait is virtually impossible: focusing his eyes were sharp eyebrows !!! rnVorrei then warn those who, by purchasing a used still under warranty, you know exactly the warranty is valid ONLY for the first purchaser registrato.rnNel Should you need to call for service you should have "assist" by those who made the first purchase: the second buyer will not be recognized !!! rnDico this because I am in these conditions and to calibrate or replace my copy before I send it to my seller (who has recorded) .rnAverlo known before ........ rnrnAGGIORNAMENTO: the Polyphoto recognized the guarantee of two years and he repaired the free lens .rnLavori played: firmware update, replacing wiring and taratura.rnrnAGGIORNAMENTO: I sold the original (even though it was "repaired") and I got a new one with serial recente.rnOra I can say I have a REAL goal: a little 'soft f / 2.8 but stopping down becomes perfect.
