I wonder how that Sigma 30mm f/1.4 compares to the Canon's EF 50mm f/1.4.

That lens seem "quite" sharp even wide open aperture, I'm very temped to get it instead of the EF 50mm, but the huge "lemon rate" and slightly higher price...

Does it cost anything (aside shipping) to get those lenses calibrated?

Not a lot of reviews out yet, but Photozone isn't duly impressed:
http://www.photozone.de/Reviews/45-c...report--review

They don't have the 50mm f/1.4 reviewed, but they have the 50mm f/1.8:
http://www.photozone.de/canon_eos_ff..._18_ff?start=1

Here's the reviews for the Sigma 30mm and Canon 50mm f/1.4 from SLR Gear:
Canon 50mm f/1.4
Sigma 30mm f/1.4

Judging from SLR Gear's MTF, the two look very similar wide open (you don't get a lot of sharpness at f/1.4 to begin with). I don't why Photozone slammed the Sigma so bad, since it's fairly close (but not better) than the Canon in terms of corner sharpness as far as I can tell from other reviews. But for $100 more than the Canon, it should be a better performer.

I'm sure it's a great lens, but if deciding between it and the Canon, you should pick based on whether you prefer the wide angle of the Sigma over the Canon.

I remember reading somewhere about "Nifty Fifties" that they are usually the best performing prime focal length because for whatever reason, it's relatively easy to optimize a lens for that particular focal length than others, hence its prevalence and popularity (maybe someone can confirm this).

And I believe Equetefue says that the calibration is covered under warranty. I hope so anyway.

Once again, thanks alot for the prompt response


Well, from the SLRgear review (and from what I understood of the graphics) the Sigma 30mm cans the EF 50mm wide open, but as you and most reviews said, the 50mm lacks sharpness -badly- at f/1.4, but it shines at f/2 up to f/11, peaking at around f/8.

To be honest until now I didn't know the existance of this lens , and from some sample shots that I found, it seems to be an exellent lens, especially color and contrast wise.

But, as far as focus range matters, having the macro 60mm and the EF 50mm seem to be close and probably even the same (sharpness wise) if I set both with the same aperture. I am really more interested in the largest aperture I can get over focus range (Not counting L lenses lol) and of course image quality matters there.

And then again, $100 more there but surprisingly only £13 (14€ / $19) more on Europe (with the ridiculous exchange rates now) £299.99 vs £313.18.

I'll give a thorough think on this.

Yeah, what you say is right: wide open, the Sigma definitely beats the Canon, the SLR Gear 3D MTF widget for the Canon is all over the place, esp. in the center. But if you slide the aperture in the f/5.6 - f/11 range, the Canon overtakes the Sigma in sharpness. Not by much, from what I can tell the Canon is right at the 1 mark on the scale and the Sigma is between 1 and 2 (lower being better).

So both have their advantages:
Sigma: sharper wide open and wider angle
Canon: sharper at narrower apertures and less expensive, and less likely to have focus issues

But if you can get for the price you claim, I would say look to the Sigma. I have the 60mm macro as well, so initially when I was prime shopping, I wanted the Canon 28mm f/1.8 but I couldn't find it for a decent price, so I went for the 50mm f/1.4, which I'm very happy with. But if I knew about the Sigma at the time, I might have thought twice, but the price might have kept me away as it did with the Canon 28mm
