Sigma 30mm F1.4 DN is Horribly HUGE :(

"Horribly Huge" is an exaggeration, but after being spoiled by M43 tiny prime (switch from canon), I have lost my appetite for "Normal Size" lens.

Here is a comparison of Panasonic 25mm f/1.4 vs Olympus 25mm f/1.8, vs Sigma 30mm f/1.4 DN

Peter --

As Dennis said, Sigma is a small company and designs lenses for multiple mounts; the APSC image circle is almost 40% larger diameter than m4/3 so optics designed for the former are well oversized for the latter.

i am a happy owner of all three Sigma f2.8 primes, all of which share the same oversized design characteristics.  Even if this lens does not meet your needs (and it doesn't meet mine), having more vendors in the m4/3 market is a good thing and we all should hope that they have good sales to encourage more offerings.

i read somewhere that the secondary lens sales rate -- what the trade calls the "attach rate" -- for m4/3 is something like three times that of dSLRs.  i hope so!

I had a Sigma 30mm f/1.4 DC (on my Canon DSLR).  Judging by the photo, I would say it almost as big....if not BIGGER.  I was hoping that the "mirrorless" version of Sigma 30mm f/1.4 would be much smaller. That is why I'm disappointed in the size.

CameraSize.com lack thephoto for Sigma 30mm f/1.4 DC (on Canon or Nikon DSLR), so I cannot do a size by size comparison.

Hopefully, someone will have a photo of Sigma 30mm f/1.4 DC vs Sigma 30mm f/1.4 DN.

Horribly HUGE is the correct description.

Hmm, larger than the 75mm.

Almost the same size as the 12-35 f2.8.

Again, not designed for mFT.  No, I don't want it, but someone might.

I'll wait until some reviews come in, before deciding. At this low price point, and considering all the hoopla, this might become a "must have" lens.

And I need to choose between getting the M43 or the Sony APS-C version.

Wait, is the Sigma with hood ON?  Seems that way to me.  The hood itself is 1/3 the total length.  In any case, if I have a Canon dSLR, I'd double-duty a Canon-mount Sigma 1.4 with a smart adapter to the m43 and 'justify' the size issue.

Its not that much bigger than Sigma`s 60mm, just a little longer and fatter, its still a pretty small lens.

Sigma's 60mm is almost exactly the same size as the PL25, in the middle of the comparison picture above. 'A little longer and fatter' seems a bit of an understatement.

The Sigma 60 is f2.8. This Sigma 30 DN is f1.4.  They're in a different league altogether.

The PL 25 may be smaller, but it must be a 'compromised design.'

The 'entrance pupil size determines everything' brigade might disagree.

The PL25 is too large compared with the 60/2.8, according to the entrance pupilists.

Whatever the case may be, most OEM lenses these days are compromised through the physical smallness of their designs, and use intrinsic software within the camera to compensate.

Some (if not all) of the Sigma lens designs have no communications of such nature, and the camera records exactly what it sees, with no compensation. This is achieved by using an optimized, larger lens design, which should produce better results, all else being equal.

This shows it to some lenses that folks may have that really aren't that large
