I need a favour from some one...

You've not read the 135L thread then.

Talking about the Sigma 30, here.

The other good things about the Pancake lens is the closer minimum focusing distance, and the sharper images wide open.
Owning both the 50 f/1.4 and 40mm f/2.8 i much prefer the 40mm on a crop camera but its a bit close on FF.
I have a legitimate need to keep my 40mm but if i only had the 50 i would get a(nother) 35/2. I had 3 copies of the Sigma 30 f/1.4, each went back.

Yes, but you said nobody comes here to talk about how good their lenses are...

Nope, said no one whose 30 1.4 (pronoun!) is working properly comes here to rave about how properly it's working.

Yeah but this is misleading because "wide open" on the pancake is only F/2.8. The 50 1.4 and 35 2 and both plenty sharp at F/2.8 too. I'm sure a good copy of the Sigma 30 1.4 is sharp at 2.8 also.

Wide open is wide open. Im not comparing f stops, just the capabilities of the lenses given their fastest aperture. Ive never read of anyone who has been really happy with f/1.4 on the 50mm.
I agree about the 35 f/2 though. Lovely little lens.

...I'm fairly happy with the 1.4 on the 50?

If "wide open" is the measure, I have this f/8-f/11 zoom that's a heck of a lot sharper than that 40mm wide open. It's a dumb comparison.

I have no problems with my 50 at F/1.4 either. Not to mention the 40mm doesn't even give you the option of a wider aperture which can hurt in low light situations. Comparison is really off-base. Kit lenses are pretty decent "wide open" at F/4 too...

No need to be sarcastic is there?, and what do you mean by your statement about your zoom?

All I was saying is the 40mm is better made in that its very sharp wide open, not like the 50mm which needs stopping down to match the sharpness of the 40mm.

Listing what one lens can do vs another is not the point i was making. I suppose someone will point out to me that the 50 is sharper at f/2 at some point.
Anyone who says they have no issues with the 50 at f/1.4 either has an outstanding copy, or is willing to live with the issues this lens is well known for.

Sorry to be crass, but the sarcasm is to make the point - comparing lenses "wide open" at two different apertures is a poor comparison. You can take a forty year old zoom lens that is "wide open" at f/8 and compare it to the 50 1.2 at f/1.2 and say the 50 f/1.2 is crap because that forty year-old zoom is sharper "wide open." The 50 1.4 is sharper than the 40 at f/2.8. "Wide open" doesn't mean jack, because you can't shoot the 40 at f/1.4, and if you are shooting the two at the same aperture (on the low end) the 50 is going to be sharper.
