Sigma 50mm f1.4 Art announced

Most photographers only know how to quantify a lens' sharpness, but bokeh contrast and other factors are however something that is well understood by lens designers, and can easily be measured adjusted. There is nothing magical about it.

Have a read through this site if you do not believe that this is something that is very well understood:

http://bokehtests.com/​styled/index.html


The 50mm f/1.2L has an extremely neutral and even circle of confusion, with very tight contrast, which is what leads to it's amazing bokeh. This is something very hard to accomplish and lets us objectively say that the 50mm L lens is a 10/10 in bokeh and therefore character.

The 50mm f/1.4 ART is reportedly tuned to have the exact same sort of circle of confusion as the 50mm L.

What this means is that the 50mm f/1.4 ART might deliver images that identical clones of images from the 50mm f/1.2L at equivalent apertures, if you just add some blur, and correct for difference in CA, distortion and vignette.

Like I said I would wait, because both lenses could have the exact same character and 10/10 look. Sigma is trying very hard to make their lens unequivocally better.

If the Sigma 35 is any indication of what to expect from the Sigma 50 ART, then I wouldn't expect it to have the "character" of the 50L. I'm impressed by the sharpness of my Sigma 35, but I've always thought that it had somewhat of a "cold" quality to it....and the bokeh can be very erratic with complex backgrounds.

The 50L wasn't the sharpest lens I owned by a long-shot....but it's bokeh is unlike anything I've seen in another lens. Between its bokeh and its color rendering, its a very "beautiful" lens overall.

different lenses, different formulas, no reason to speculate it will be the same.

Just came across the Sigma Art 50mm for sale at Buydig for $899 with free Hoya UV filter.

Well everyone is a fanboy of something. Does it make you a Sigma fanboy by praising a lens that you don't even own yet?

Maybe it's a good time to pick up a Canon 50L. I hope the Sigma is as good as all the rave here. And if not then I hope it's good enough that the price of the 50L will drop to around $900.

I am a fanboy of all things I like regardless of brand I think most people fall in this category.

I am being super optimistic, based on nothing but talk and no facts, yes I agree. I am also making a lot of assumptions, but I feel that where there is smoke there is fire in this case and I have been itching for a new 50 for a while, hence my optimism. I am also having fun getting excited for something, remember like when you were a kid and anticipation of Christmas was more excitement than the actual presents? I have to be serious for a majority of my life, I am allowing myself to indulge in some childish excitement based on promise for something I do as a hobby.


I like how buy dig has 3 reviews, soooooo what is that about? They are all 5 stars

I have the 35 f/1.4 and I know 35/50 are fairly close, but I'll still buy this. Sigma really got me with the 35. It's such an amazing lens. Hell, I might even buy an 85 ART over the Canon 85 f/1.2. Sigma has REALLY stepped it up. I just hope we do get the $899 price.

is there a 85 sigma ART lens?

Not yet, but it's only a matter of time.

why hasnt canon updated ANY of their L prime lenses?

IMO most of them don't need an update, what they need is a price reduction to stay competitive.

Oh now you've done it. Here comes another ten pages of discussion about everything that's wrong with the 50L.

Look up canon museum. They have been updating L primes for the past 8 years. Since 2006, Canon has updated or newly released every single L prime from 0-200mm with only the following exceptions: 35L, 135L and 200/2.8L (the 200/2 was released though). And they have updated several big L's >200mm.

I've been wanting a good 50mm for a while. Haven't been able to decide between the Sigma 50 1.4 and the Canon 50 1.2. Don't NEED the lens, just want a great prime in that range. I have the nifty and do use it.. I'm hopefully awaiting this. If it's anywhere near as good as it appears it may be, and still less than the Canon 1.2, I may have a tie breaker. I really hope it's available by my June trip to Canyonlands... If not, I may rent the Zeiss for the weekend.

The zeiss is amazing for landscape work.

On another note, if the sigma is as sharp as those results portray, the L lenses will drop in price. The Otus will stay the same.
It has a close minimum focus distance, which is just wonderful..
Sigma didn't exactly hit it out of the ballpark on the 24-105, so I'm glad this 50mm shows great early signs.

ahh is it?

did they update the 50mmL?

i guess with lenses you can expect them to update every 3 years lik camera bodies.

Fair enough but i think the 50mmL may be long overdue for a update as the build mechanics are strange as people have pointed out.

the 85mm f1.2 is ridiculously expensive though!

So, no one else curious as to the buydig page and reviews?
