Summering: Using a Canon 70-300mm EF 4-5.6 L IS USM for pretty much all of my wildlife & dog photography, I had previously invested in Canon 100-400mm lens in order to extend the reach. Whilst this is a good lens, I wasn't too keen on the 'trombone' zoom & I couldn't shoot close subjects, so I decided to look for another lens which would give a greater all round scope of focal length. After due consideration, I decided on this Sigma which arrived today.
Summering: The Bigma, love it. A great compromise lense for amatueur photographers wanting to get close, very close. Capable of brilliant shots but in reality most of us wont provide the stability for precision sharpness. Recently taken to the Kalahari and obtained excellent close-ups. Cons: Sadly poor weather sealing. I trip and significant dust inside the lense.
Summering: the reason i purchased this lens was for wildlife photographs the challenge is to get close without disturbing the subject and to capture movement-when using this lens with the sony A77 and the build in teleconverter set at x2 i get continuous focus at a long distance when the subject is moveing yes it is heavy but i knew the weight it was before i purchased it this is value for money
Fördelar: Durable, Easy To Use, Improves Product Function
Summering: Having used the Canon Ef 500mm f/4.5L USM for many years, I decided it was time for an upgrade, as this lens had certainly seen better days. My first inclination was to go for Canon's latest incarnation, the EF 500mm f/4L IS 11 USM, but the price was way out of my current budget range, having just purchased a new 1DX body.
Summering: Bought this for use mainly at Airshows, so far it has been great giving good quality photos. Auto zoom and stabiling lens works a treat. The only down side is that it's quite heavy for carrying around the neck for any long period.
Utdrag: Ho usato questo obiettivo per un paio di settimane e lo considero uno strumento meraviglioso. Dà la possibilità di zoommare fino per a 50 volte per ottenere un fotogramma preciso del dettaglio che volete inquadrare. Riesce a ingrandire per primi piani spettacolari. Avevo anni fa in estate un paio di nidi di rondine sul tetto di casa mia.
