I'm looking for help with choosing a decent tripod. I use Nikon D7100 (800g), the heaviest lens I own at the moment is Sigma 18-35mm (800g), but I plan to buy 70-200 2.8 lens (weights around 1500g). I will be using it outdoors, on moderately long hikes, walks, travels, mostly in wet climate and strong winds. My initial plan was to buy Manfrotto Befree compact, but after reading several reviews I got an idea it doesn't absorb vibrations well and is pretty unstable in windy situations. So, I'd...

Just got the above, along with a Sigma USB Dock. Mounted on an A6000. Calibrated the lens, but the AF is pretty lethargic, and accuracy is hit or miss. I'd say around a 66% success rate, even on highly detailed items in daylight. The center and top/bottom most AF points are most accurate, being more sensitive, with the others having less chance of success. The combo also does not continually AF during burst shooting. Is this just the way the Sigma 18-35mm is, or do I have a faulty LA-EA2?

With my new shiny a77ii same day arrived sigma 18-35mm F1.8 DC HSM (Art). On jpeg's I see good sharp results if I took steady shot, but on RAW files almost all photos are a little bit blurred (looking at the eyes). Not big specialist, but I understand that camera makes some adjustments for jpeg , but it should be also sharp on RAW also.. What should I do ? How can I check and adjust the lens ( I know there is micro adjustment) ? Is there some special procedure on what length and aperture it...

I currently own the cz 24-70 and love the shallow depth of field at 2.8 but my recent purchase of the a77ii mk2 has made me question the need to keep my a99... the dynamic range of the a77ii is pretty close the af is outstanding so my only only reason I keep the a99 is the shallow depth of field in low light. The art lens on the sigma 18-35 f1.8 will give me the reach I need for most of my shots Has anyone took a step back into these new art lens and compared the results... The a99 is a way...

Which is a better value? Sigma 18-35mm is $725 if used, and Metabones is $649 from what I see (Canon ef version). About $1400 vs $1000 for 12-35mm Panasonic. The lens will be used with my GH4. I know the Sigma has a better/larger focus ring, and somewhat better build quality, but is it worth the price difference? After borrowing my friends Sigma + Metabones (he has the Nikon version though), it is nice, but not sure if it's worth the extra cost. One advantage I see with the Sigma and...

I have a D610. My main priorities: 1:Does 2.8 really give a significant more amount of bokeh to the 4.5 minimum aperture? Is it worth giving up a nice light lens like the 18-35, and the 18-19mm, to have a 2.8? or is 2.8 not a huge difference in bokeh to the 4.5? 2: Which one is sharper? Overall, corners and center. 3: Which one distorts more? Chromatic aberrations on which is worse?

Hello, I own Canon EOS 70D and I´d like to ask if its worth to upgrade lens from Canon EF 17-40 f/4 L to new SIGMA 18-35/1.8 DC HSM ART. What I care the most about is image quality. I shoot mostly outdoor portrait, weddings and proms. Thanks

Sorry, this is going to be a long one... My wife and I have been doing Wedding Videography for a few years now and this year we would like to do photography as well. I've been a second shooter before (using Canon). My wife has done many family/child sessions and this year we will have a couple of paid photography events. Our current gear (I have lots more but selling the rest) includes the following: Sony A7S Panasonic GH4 Panasonic 12-35 2.8 Panasonic/Leica 25mm 1.4 Metabones Nikon to m43...

Hello, I am looking to replace the kit lens for my D5300 with better glass (within the same zoom range as kit lens). I intend to use it as a general purpose travel lens. I mostly like shoot landscapes and some landscapes of people in foreground (to share on social networking). I usually don't like to change the lens as I do not have any specific purpose to do that. I just want to take better pictures to share online and may be couple of prints for my living room. So I just bought just the...
