14/1.8 Art? drinb27x24.gif 

 

Happy me, I stayed away from their 12-24 Art. And the thinking process about "15 or 11mm Irix firefly?" is not finished. Sigma would be something worth a closer look. 

 

As for the rest: zeitg29x23.gif (okay, the 100-400 could be cool)

 

A couple of kilograms more glass in the shelves.

What is a contemporary lens (i.e, the 100-400)? Does that suggeset it will not be in the same league as an art lens ?

Well, yes (see the 150-600 C vs. 150-600 S, even though the C lens is still reportedly very good.

I am more surprised not by the C designation but by the aperture - which, in all fairness, would probably allow it to be more compact. However, these two factors combined lead me to the thought that there may be an S version to follow which would likely directly compete with the Canon 100-400 II and the Nikon 80-400 G. :)

 

As for the other... the 24-70 doesn't really interest me; the 135/1.8 would be cool - remember that in the late 70s and early 80s there was a thriving market for 135/1.8 constructions with Sigma providing some of them - but I feel that a 135/2 OS might've been a better idea.

 

The 14/1.8... woohoo. I can only imagine how large it might be - at least as big as the 20/1.4 and with more curved front glass. Maybe my 14/2.8 is in danger now (even though I'd like to see an even shorter FL lens instead like a 12/3.5 or 12/4). But if they can pull it off... one more notch for unparalleled technical achievement to them!

Well if 24-70f2.8 OS ART is good enough, finally in Canon land there's an alternative to 17-55f2.8 IS, I still have my full frame gear, will wait before selling.
This one should be a hit, let's see size and weight of 135mm f1.8, anyway canon 135mmf2.0 is hard to beat.
As for the 100-400,unless price argument dunno where is her place between the 150-600 and the excellent Canon 100-400 that is very decent and almost one stop faster

I'm pretty sure there will not be a Sports-version of the 100-400 - it's meant as a Superzoom for those who are not happy with only 70-300. A lot of the C series is only in that series, there's no 17-70 Art or Sports. The Fuji 100-400 also has f/4.5-5.6, but I reckon the Sigma will be around half the price and still decent enough.

 

Today I saw three lenses we recently talked about: The 105/1.4 G, the Sigma 85/1.4 A and the 500/4 S. The Nikon is already a nice bucket, but the Sigma throws enough shadow to make the Nikon disappear  ^_^ the 85, that is. Extrapolating the 85/1.4 to 135/1.8 I imagine a thing which will nearly be as big as a 200/2. Good luck with handling (and finetuning) this monster on a DSLR.

 

The 500/4 looks really cool.

Some pictures have leaked - I'm not sure how authentic they are. But an 82mm filter thread is implied for the 24-70 and 135, 67mm (!) for the 100-400.

http://photorumors.c...mporary-lenses/

I think there may be yet hope for a 80(100)-400/4.5-5.6 - after all, Sigma has a current (?) 120-400/4.5-5.6 model.

120-400??? I know of a 120-300/2.8 Sports but the one you mention I could not find at Sigma US or DE - do I need to look a RU?

 

Only M82 for the 135/1.8 - the theoretical ø is 75 mm for the glass. M82 would be a bit close to the front lens? The 24-105 has M82, too, but only f/4 - I doubt the 135/1.8 will be so tiny. The 85/1.4 has M86 (front lens theoretical ø 60.7 mm)

I guess Zeiss won't be the only one to offer such lens.
Do you think Sigma will use APO element?

Look no further than Photozone, Joachim. :)

Looks like this lens was discontinued in the interim - so that's one more reason to expect a successor. Whether this new 100-400 is one remains to be seen. :)

 

Re: the 135/1.8 filter threads - there have been some such lenses with 77mm filters (most importantly, the fabulous Zeiss ZA). However, 82mm is the new 77mm anyway. :)

looking at Photozone is sometimes looking in a museum  :D The test is 6 years old and when was the last first time PZ tested anything when it just came out?

 

I admire your search skills and doubt my math skills. I thought more or less to rely on the Focal length ÷ aperture number = front lens ø ? Must be totally wrong: The Sigma 50/1.4 Art has ø 60.5 mm. After my equation it then should be f/0.82 So forget this stupidly simplified math.

I hope that you don't apply this logic to the wide angles, else you might've arrived at some decidedly odd results when analyzing, oh say, a 16-35mm lens.  ;)

 

Search skills have nothing to do with that, but I remember both the introduction - around eight or nine years - of that 120-400 (that superseded a couple of earlier lenses, the 135-400 and 80-400 OS) and that review appearing. After all, I must be the most avid (and rabid :)) reader at Photozone. :)

With "search skills" I was referring more to the list of all 135/1.8 lenses. And like I said, museum lenses are not of much interest to me. :D  Even as second hand I would not waste money on a 2 1/2 star lens.  B)

 

The Ø relative to the Focal length is more the diaphragm diameter, I realize. But I always thought the front lens diameter should be as big as the max aperture? Not that I understand any law of optics... :unsure:

Yes, it should be at least as big - that's why we're seeing relatively few long/fast lenses for crop sensors: you just have to use big elements in the front group(s), and then there's already no point in implementing small format. :)

 

Re: the museum lenses, this chart came from the FredMiranda.com forum - a MF lens aficionado has compiled it and it was fascinating to me, so I saved it for myself. Even though I'm not really a MF man, it's interesting that there was a thriving market of lenses with "extreme" stats even back in the late 70s. :)

This 14/1.8 Art is kind of tempting. At first and when sometimes taking pictures in dark rooms. But then I remember the troubles I had and still have with AF on the 20/1.4   :mellow:  Somehow I don't think, a 30% wider lens will decrease those probs. this is really the playground for mirrorless - on my Nikon, the AF problems were gone as soon as I used LiveView.

Well the previous Sigma 24-70f2.8 had 82mm filter, I have used it extinsevely on 300D and 30D and liked it a lot, it has been my main lens along with Sigma 20mm f1.8 for three years, when you upgrade from EFs 18-55 kit Mk one that was on my 300D to this one you will be very happy with it :)

Just saw a new Fotodiox adapter for Fuji GFX and 5 different mounts, amongst them also one for Nikon; https://www.dpreview...x-lens-adapters

 

Fotodiox says, each lens above 50 mm should work, although strictly manual, no EXIF, no advanced electrical functions - but as I see from the picture, at least the mechanical (not electrical) diaphragm changement is possible. That would mean for me no 300/4 PF E, no Tamron 150-600 G2 (also electrical driven aperture), but a 50/1.4 and a 105/2.8 macro could serve me in the beginning. as well as the Sigma 135/1.8. Cool? Not sure.

You would just use the lens wide open. That's a lot better than the lever-operated aperture on older Nikon lenses that was stuck at the minimum aperture when not operated by a camera / special adapter. :) With the 300/4 PF I imagine you'd want to spend a lot of time wide open.  ;)

 

As for the Sigmas... for what it's worth, the future is here.
