Amazon customer service really let me down with this purchase
13 March 2014
Summary: First of all this was shipped and sold by Amazon, I don't want this to reflect on any of the other sellers. I ordered the Canon lens and they shipped me the Nikon lens. Unfortunately I need this lens by the weekend and the only resolution after a 38 minute phone call was the following: 1. Issue me a credit which will take 3-4 days to hit my Amazon account. 2. Issue me an RMA through UPS. 2. I have to re-order from one of the "Other buying choices". 3.
Summary: I bought this for Google Business Photos. I only used mine a couple of times and am now selling it for $650 plus shipping ~ I wonder why they raised the retail price of it, I bought mine for just over $700 but retail is now more than $800. If you want to get one hardly used in perfect condition just scroll down to see the used fair. Amazon are handling the product - Why buy new when you could save a hundred dollars?
Summary: First time I've bought a 'used' item on Amazon. I wouldn't have known it had been previously used if they hadn't told me. Packaging perfect, the lens works just as expected, and saved me some cash too.
Summary: I'm using this lens with Canon EOS 6D full-frame camera (5D previously), and my previous fisheye lens was Peleng 3.5/8mm . The Sigma's optical quality is truly excellent in comparison with Peleng. The most important thing is that the resolution is far better than the Peleng's. It exceeds the capabilities of 12 MP sensor (5D) and looks very good at 20 MP (6D). This lens gave a huge boost of quality to my spherical panoramas.
Summary: After reading hundreds of reviews on a variety of fisheye lenses, my choice of going with the Sigma 8mm f/3.5 has exceeded my expectations (which were high to begin with)! By far it wasn't the most expensive lens in the running, but I seriously doubt that I could have made a better choice than this!
Summary: If your in the google tip program this is the lens you need. Not the 8mm f4. You really don't have any other choice..so just buy it. For non TIP people. This lens will make a circle on a full frame camera and a bit less with APS. Its not a normal fisheye. You buy this for virtual tours and such. Its a very special lens, if your looking for the typical fisheye, but the 8mm f4 or other fisheye lens.
