Third Party Manufacturers / Sigma 24-104 f/4 lenstip's review
« on: November 15, 2013, 05:00:50 PM »
nothing spectacular but optically better than nikkor and canon

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!

and in the meanwhile nikon may die and you will be here bashing canon and supporting who... sony, pentax, Samsung? lol

Sigma's biggest strength has always been and continue to be their pricing.

and recently the optic quality too

EOS Bodies / Re: 7D2, 6D2, 5D4... USB3?
« on: September 29, 2013, 05:11:57 PM »
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.

my hdd is faster than 100-200mb/sec and by a lot...around 500 mb/sec attached on a sata3 controller, but i guess it would take a quite big performance hit if attached to a usb 3.0 enclosure

and yes, to have an usb 3 would be preferable than an usb 2, but you would need a good hardware to exploit the full potential offered by the protocol

it's not only a matter of usb 2 or 3; downloading images from an UDMA from a canon 50D (udma supported) and a USB2 10€ card reader (with UDMA support) is faster on the card reader

EOS Bodies / Re: An Update on the 75+mp Camera in the Wild
« on: July 28, 2013, 06:02:45 AM »
fuji has more DR than nikon sensor and they are being outsold by nikon too... so better the DR worst the sales of cameras; canon execs have to care about their stakeolders, that's the reason because they dont improve DR on their sensors

EOS Bodies / Re: Buy 7D now If I won't be able to afford 7D mkii

if you like so much the 1dmk2 why not to buy a used 1dmk3 (or a mk2) instead?

EOS Bodies / Re: Canon EOS 70D Spec List
« on: June 27, 2013, 04:19:31 PM »
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.

needs just to be better than d7100 and with those specs probably it is

at least it's not a joke like the 60D; it looks likes a real XXD body

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.

is it will work, as all others DC sigma lenses; it's likely you will get an heavy vignetting at 18mm. i guess we will have more reports on this when the lens will become widely avaiable

yap the sl1/100D is really wonderful

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 :D

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.

i had the HSM mk II and it was front focusing a lot on 50D (i ended with a +16 mfa) and almost perfect on 450D...so the fault is Sigma or Canon? And i have at lest one more person that got the same results... weird; then some months after i got the OS version of the lens , beacuse of a good offer from amazon in eu, and the focus was quite good on both cameras (just a +3 to achieve the maximum sharpness). And dont think sigma did a lot of 70-200 because as far i remember there are four lenses so far

1) 70-200 APO
2) 70-200 HSM
3) 70-200 HSM II (it's not a redesign, it's a rework to make the lens cheaper, so smae perfromance)
4) 70-200 HSM OS (total redesign)

canon did 3.

know peoples that had to exchange the Canon 35L 1.4 twice before they got a good sample and for what i know, canon doesnt offer free calibration for their lenses, at least here in italy, but maybe i am wrong, because i own just a canon lens (a shitty 17-85... +5 for the record); i am not sure it's completly a sigma QC fault the AF problems, because with nikon the problems are not so pronunced as with canon. i think the accuracy of focues with canon camera is more firmware dependant than other brands, but with the new dock, i guess a lot of problems will go away

EOS Bodies - For Stills / Re: Lens for European Trip
« on: May 18, 2013, 09:58:50 AM »
I am narrowing it down to EF 24-70 v1 or EF 24-105. Will accompany 5D3 and getting XA20 when release in June.
Thought or suggestion is greatly appreciated.

the 24-105  is a better option in my opinion, mainly for the IS, secondary for the extra reach. Also a wider angle lens would not a bad idea, like the samyang 14mm manual lens or a thing like that (buy for the trip, resale after if you dont linke) or something like that

Actually I too have been contemplating on getting the SL1 for myself (to have my Sigma 150-500 OS, permanently mounted on it ... which would give me an awesome 800mm reach, something which I miss after I sold my 7D & 60D) ... I had originally planned on getting a Sigma 150-500 OS for my Nikon D7100 and sell my current Sigma 150-500 OS for Canon Mount ... but I'm still a bit undecided about which one to get ... so thanks for asking this question, its helping me out as well ... having read some of the replies here, I am now leaning towards EOS SL1 (100D), but still undecided :-\

get a used 7d...i am thinking to get a 100D to replace the 50D but not planning for sure to use it with a so long tele (avifauna?); just to use it where a reliable AF servo isnt important
