sigma

G'day guys! As the title says.. am I having focus issues with my 80D? Recently I purchased a canon 80d and sigma 18-35mm as my upgrade coming from a 700d. First thing I noticed was back focusing (further than intended focus point) using the sigma lens, minor at 35mm but ridiculous at 18mm. I...

Hello! I'm a professional photographer who has lived in Vietnam for 9 years. I'm back in Ottawa visiting family and am bringing my 300mm 2.8 back to sell. If you are looking for an insanely awesome lens to shoot sports or wildlife, take a long hard look at this particular lens. Its in...

Selling a practically new 105 macro for Nikon. The lens is in perfect condition and was used for one publication project, resulting in around 55 portrait photos. This lens is a great portrait and macro lens. I don't have time for macro photography and I have portraits covered with a 200mm. It...

So I bought a new sigma 18 - 250 lens, and I noticed that when I am looking downwards to take a photo (at an angle of 45 degrees downward or more) the part of the lens that moves to zoom slides out from the spot that I had it at. However, this does not happen if I have the lens fully retracted...

Sigma announced a few new lenses yesterday, the 12-24 f/4 ART being one that interests me the most. Sigma says there will be very little distortion. When I saw this announced, I thought it was for crop sensors but turns out it's for full frame which I guess its suppose to replace Sigma's other...

Purchased this lens new November 2015. It's some of the best glass I've ever used, however my business is becoming more focused on work in tough environments where a studio/portrait lenses like this can't go. The pictures should answer any questions you might have regarding condition. It was...

Hello.. I have a Nikon D5100, and I am about to buy a new lens. I have my eyes on either the Sigma 10-20mm f/3.5 EX DC HSM Or, The Tamron 10-24mm SP AF Di IIs They cost the same, so I btw also have the question about which you would choose, of those two? I am maybe mostly into the Sigma...

Hi all! I have a Nikon D3000 and currently have the following lenses: - Kit lens (Nikon 18-55mm f/3.5-5.6G AF-S DX) - Wide angle lens (Sigma 10-20 mm) I'm looking for a lens to complement these. I LOVE my wide angle Sigma, but only use it for landscape and architecture photography. So I've...

So basically what the title says?

My D50 will auto focus if I put it on Auto, but will not auto focus on anything else. Seemed to happen out of nowhere. Shooting fine, then all I hear is a slight buzz indicating what sounds like a desire to focus, but nothing. I have a Sigma 18-125mm lens.

"Subdued" I went out to Diana's Pool in Chaplin for what seemed like the 20th time, with the intent of trying out my new tripod. I decided to go at it a bit differently, and with the trees still being pretty dead looking, I knew I wanted the final photo to be dark and moody. RSP_1529 by...

i have a Sigma 120-300mm f2.8 no OS and am control atone selling it so I can buy a 70-200 OS F2.8 lens. The brand will either be a Nikon or Sigma. I have a Nikon D300s and Nikon D700. Should I sell my 120-300 to finance the 70-200?

Hi, I bought used Sigma 24mm f/1.8 EX DG Macro for Nikon from eBay. I am worried because front element is little bit loose. So it moves sideways and makes a rattling sound when I shake it gently sideways. It works well with camera and takes ok photos in my books. There is little ding in lens...

I'm shooting indoor club level basketball. I was getting good results, now not so good. Canon T2i with a Sigma 17-50mm f2.8 using the AV setting with ISO 1600 to 3200. I'm shooting continuous, AI-servo. The lighting was similar a both shooting events, but different gyms. I'm wandering if it's...

Alright, let me explain this: I recently bought a D7100, lovely camera for sure, but I'm still looking for the "perfect" lens. I mostly shoot landscapes and a little bit of architecture (well, more like cityscape, to be honest). Coming from a D200 I started with a 18-55, then switched to my...

Hi, I Would love to get your advice on the minimal lighting setup required for taking a group photo of over 50 people. A beautiful charity group in my hometown are going to use this photo for their advertisements, and when I heard they're going to shoot it using their mobile phone - I...

Mini review: Sigma 150-600mm f/5-6.3 Sport

After much research (and some opinions on here) I bought a Sigma 70-200mm f2.8 lens for my Canon t3. The auto focus is off. I was reading on how to calibrate lenses to cameras with things like the Focus Pyramid, but I can't seem to find the option to calibrate in this camera. Am I missing...

Hi guys, This is my first thread in a discussion section so if there is anything I did that's against the rules, just let me know and I will edit it immediately! I had been having focus problems on my Nikon 50mm f1.8g. Plus, I recently purchased a Sigma 17-50mm f2.8 which (based on what I...
