Sigma announces f/1.4 zoom lens - Fastest zoom ever!

Looking at my keyboard, I see that the ':' key is diagonally adjacent to the '.' key. Someone at Sigma's graphics department made an oopsy. :P

They emailed a correction a few hours later.

Been a long time and manufacturers still use non-standardized specifications that confuse the unwary buyer. :( One is opening diaphragm that writes F4 or then 1:4, which seems to F1.4 and confuses even experienced photographers. Another thing is the magnification as fraction (magnification 1/2) or decimal numbers (0.5 x magnification). We will reach an agreement that does not create confusion? ???

Confusing? What's confusing about DG OS HSM | A ? ;)

All I can say is, ROTFLMAO... ;D
I helped a friend who was looking for a Sigma 18-50mm lens used, and the search was arduous. Many vendors do not properly informed in the text, what exactly were model selling, or put photos of another different model. >:( Could be:

Sigma 18-50mm F2.8 EX DC
Sigma 18-50mm F2.8 EX DC Macro HSM
Sigma 18-50mm F3.5-5.6 DC
Sigma 18-50mm F2.8-4.5 DC OS

There is no patience and perseverance that is sufficient. :-[

Confusing indeed! Hopefully the sarcasm in my last post wasn't lost in the barren landscape of text-only communication. :)

With so many letters and numbers (even a pipe!) designating each model, Sigma would probably feel right at home with a government contract...

With all that sarcasm, I'm not sure if you realize that this is simply a feature list which gives you everything you need to know about a lens (bar the image quality, obviously). All manufacturers, including Canon, do this - the inspiration for this lens, for instance, is called the Canon EF 24-105mm f/4L IS USM. They could give it a name, but instead they list seven (!) features.

Btw, I really don't know why Sigma puts DG on their lenses, when they have DC-lenses too. And THAT one you really want to be aware of. I'm still plenty pissed my 5D3 won't take that nifty new f/2 zoom they made...

Understood. Just having a little fun...

I'm sure glad they don't do that with car models! :o

Should I get the Honda 1.8L 16V SOHC 5SMT 38MPG VSA or the Honda 1.8L 16V SOHC 5SAT 38MPG VSA ACC? There's a $2,650 difference in there somewhere... :P

If someone has to decipher all the abbreviations and designations in a name, we might as well go with Honda Civic LX and Honda Civic EX. Besides, it fits better on the back of the car. ;D

(I know I'm exaggerating a bit, but why not have a little fun?)
