Of course not many wanted to buy yesterdays shitty mirrorless. Dwarf-sensored nikon 1? Slow as molasses eos-m? Retro styled fujis? mft-sensored stuff? Poor EVFs? Give me a break!
It will change as soon as really good ff mirrorless arrives. Sony A7/R are the first inkling. Even better stuff will follow. Dslrs will be gone. Like all those german rangefinders went out the door in the 70s when good SLRs became available from the japanese. This time round it might be korea and taiwan doing it to the japanese. Hehe!
Sigma's biggest strength has always been and continue to be their pricing.
On my old S3IS I just plugged the camera in and downloaded. The downside was that Canon apparently doesn't like just any old program looking at files on that camera, I had to use their software, so you have the potential that some bureaucrat will decide to limit when/how you access your files.
If properly implemented it would be preferable to use USB3 over a card reader, and I wouldn't worry about future compatibility, it will be quite a while before any flash cards (at least sub $1,000 ones) saturate the 400MB/s bandwidth afforded by USB3.
Not that the peak bandwidth of USB3 matters much since the your HDD will still only write between 100-200MB/s. Unless you run multiple drives in RAID or plan on buying a lot of flash storage you're not going to be able to saturate USB3.
The bottom line is that USB2 at 10-20MB/s is terrible, and should generally be avoided if you care about data transfer time.
Very similar specs when compared to the 7D. I would have thought that this needs to be better than 7D in all aspects including fps.
Dumb question. will the new Sigma crop zoom work on my mark IV? I am fixing to do some traveling I hope. And only want to bring one lens for landscape and people.
I didn't say when I went to Focus on Imaging, it was just around the time for their Macro HSM mk 1 I think. Again it was so far out of adjustment, I called over the attendant and he confirmed it. And then put the lens under the counter with a post it note on it. It was worse than my old copy.
It's been surprising how many 70-200mm f2.8 lenses Sigma has put out over the years. I'm assuming this is to correct various design faults with each successive model. Other brands like Nikon or Canon tend to get it right first time and let that model run for a good 10 years or so. That said, I took some great pictures with my old copy.
My 70-200 EX HSM f2.8 (new at the time) was so far out of calibration...it had to go to Sigma twice with the Camera. It was bad. I'm not going to re-tell my Sigma woes here again, I did that a few pages back. Hello if you are new to this thread
I've sent only one lenses back to Canon for being out of Calibration, which I did under their 1 year warranty. It didn't cost a thing and came back perfect.
Yep, it true about the new Siggi 35mm, it's a fine lens from Siggi. I don't think it destroys the Canon, but it's a sharper lens. I've had my Canon copy for about 5 years now and I've taken a lot of photos with mine. It's easily paid for itself many times over. The Siggi fisheye's are very good too and I particularly have a soft spot for their 12-24mm, although my copy had been back to Sigma twice.
