 I'm 'done' - I have all the lenses cameras I 'need'. Now I want a 70-300L for travel  ::) ::) ::)

Here's my snapshot from the other night.

ISO 3200
35mm
f/2.8
1/125

Like I said previously, I thought the flare my just be caused by my filter. After reading this thread I'm 95% sure it's just the mirror box in the camera now. Not a big deal... I've never had this type of flare before in any image that really counted.

Thanks for posting, it's the familiar flare alright. It looks like there is a small spike in the snow on the road as well... At least it's confirmed it does not only occur with Sigma lenses, and given the right conditions, almost any lens can produce the effect on the 5D Mark II, at least those with a wide aperture.

FWIW I like the fact they kept the 77 mm filter size :)

245
Anyone notice this?

every lens is tested with Sigma’s proprietary modulation transfer function (MTF) “A1” measuring system before being shipped.

I think Sigma is really stepping it up.
First came adjustable focus - i.e. goodbye frontfocus problems.
Now: Goodbye decentering problems.
and at $900 this lens will be sharp and it'll have wonderful bokeh.  I have no doubts.
I think Sigma will be the new Zeiss - i.e. a premium 3rd party brand.

This is what they announced when they introduced 'Sigma’s Global Vision'. Going by their recent offerings, they've really stepped up the QA/QC and of course, overall quality. I've got their 35mm and it's every bit as good as people say.

What didn't you like, specifically? I'm actually having even more fun with this lens on the MkIII than on the MkII although it's harder to check critical sharpness on the Mk III at wide apertures (my Mk II has a precision matte focusing screen). On the Mk II I use manual override to tweak the sharpness at wide apertures, on the Mk III I've set AFMA +8 for this lens.


FYI, I got a matte focusing screen for my MKIII from this site and it works great:

Thanks for the link! I've bookmarked it for reference if I decide to go that direction. How does your 5D Mk III meter with this screen?

247
And the difference between, say the 35/1.4 and the older 35/2 is considerable.

I've got one of those 'old' 35/2's, and I love it for its tinyness. That, and the 50mm 1.8 mkI are great little primes that can always find a corner in my bag if I think I might need a prime but don't want the bulk, for instance when I travel :)

I'm very happy with my current f/1.4 Sigma - but did anyone notice the maximum magnification ratio of 1:5.6?  The MMR of the current model is only 1:7.4, something I stumble into when I do museums with this lens.



I used to own the 50mm f/1.4 and used it on a 550D and 7D. Great lens for museums.
Africa Museum - very little light inside
550D iso3200 and f1.4(of course) - there is some noise here


It's a fabulous lens for this application; only the small displays could use a little more magnification though (on full frame) but I don't consider 1:5.6 vs 1:7.4 max magnification to be enough of a difference to justify getting the new Sigma for this feature only ;)

I visited a museum for ethnic sciences, they have some African stuff too :)

I must admit, I did not like the sigma 50 on my 5d MKIII. I sold it but I am awaiting the new sigma. First I would like to see some reviews with field examples using a FF camera

This looks (maybe?) like the first genuine replacement for my beloved pocket cam, the Elph 500 HS, which is 24-105 and f/2 at the wide end, unlike all the newer, slower Elphs.  And this one looks like it has the 1/1.7" sensor size of the S-series and G-series too.  I wonder how thick it is, though.

Never mind.  Way too thick.

No one has yet come up with a more perfect pocket camera than the Elph 500 HS, IMHO.

I had that. and sold it because the jpg's had a greenish tint. And the long end of the focal range is not usable  due to the body being so tiny. We all wish for different types of perfection ;)

Good for lens collectors, but I imagine many people in the field would rather take the 35mm and do some cropping. That's what I'd do, at least.

Shoot a subject against any background with the subject being the same size with both 35 and 50 and you'll see just how different it looks. A 35 and 50 are different beasts.

I'm not saying that a 35mm replaces EVERY 50mm. I'm saying that, for me at least, it replaces a 50mm with the same characteristics and optical signature. I'd rather invest the money in something that really lets me do something different or at least in a different way.

Always in my opinion, of course, 50mm is a useless FL unless the lens you're using is really special (and I found a little gem in the CV Nokton 58mm). It's usually too long for a walkaround and too short for portraits. I'd rather have with me a 35mm and a 85mm instead of a 35mm and a 50mm - again, especially if both lenses have similar characteristics.

This time of year (when it's generally dark and glum) I find I carry both the 35 and the 50 a lot of the time. These focal lengths really are very different and have their specific uses although they can both perform as a general purpose lens depending on ones preference. Aside from the angle of view, the perspective is much more important. It took me a while to understand the 35, but in certain situations it offers me the ability to create pictures with more 'drama' to them.

Just want to add that I was shooting with the 5D2 late last night with my 24-70 f/2.8 II and experienced this same sort of flare in one or two of my photos. I put it down to the filter at the time, but after reading this thread regarding the phenomenon occurring with only the 5D2, it makes sense as I've never seen this lens have that flare on my 5D3.

Looks like its nothing to worry about. I'll post my flare picture tomorrow from the 5D2 and 24-70 II.

That would be interesting, please post the pictures :)

I also decided it's not something to worry about, rather just be aware of. in 32000 images I took with the 5D Mk II only a few pictures show this effect which, depending on ones preferences, may be disturbing (or not). In any event, I'll try to avoid its occurrence in the future when I use this camera body.

253
I made a ahem paper "replica" to get my head around the size. Seems about the same size and thickness as an average coffee mug.

Observe.

Without comparing like for like, that is a big lens. In that sense I think I prefer my current Sigma 1.4, just for its size (and it is also not a very small lens)...

254
I mean, obvioiusly I'm comparing his A7R to your EOS M, and they may be apples to oranges, but really.... Canon may already have a A7R killer... just saying.
In fact, if I'm not wrong, Sony themselves may have an A7R killer, it is called the NEX 7?

no ... on all counts. Everything mirrorless except the Sony A7/R is just a 5c gumball game. :-)

  • EOS-M has no viewfinder, no built-in flash, no 135 sensor. It has just sold due to 5c gumball firesale price
  • Sony NEX-7 is too large for a crop sensor and has a god-awful, unusable NEX user-interface.
  • mFT and 1" all have too small a sensor for still too large body and lenses
  • EOS-M2 has small enough body, but not even the Japanese got a compact "folding-design" kitzoom for it
  • Nikon brings such a compact folding-design DX 18-55 VR II kit zoom, without having a matching mirrorless body
call it funny or just plain stupid.

Not funny: Sony A7/R unfortunately is not good enough ... I am really grateful for the user reviews here! Saves me having to purchase one and find out myself.
sigh.  :-\

So I correct my previous post. I want a "Sony A8R killer" from Canon. Whatever it's called, make it good, make it 36x24 sensored and make it free of moving parts. :-)

Well, because nothing is perfect I got the Nex-6 as the best possible compromise. It's better than the Nex-7 from an ergonomics point of view and quite compact too with the collapsible 16-50mm F3.5-5.6 OSS. The controls are easy to use, but I agree the menu could use a lot of improvement (I miss the Canon interface a lot on this camera).

One more cause I found it. It may be the mirror but it's a combination of mirror and lens I'm pretty sure, I never really saw it on the 35L. Maybe the curvature of the back element make s a difference?

I think the Sigma 35 does make the camera more prone to showing this effect. Fortunately now that we know why this occurs we can at least take it into account and turn the body 180 degrees if necessary.
