The full brochure can be found here: http://forum.xitek.com/thread-366376-1-1-1.html . I am not sure if the poster agrees to put the image here.

Excuse me for asking, are you the poster in that Chinese forum?
I did not have the link you mentioned, I had only the Sigma catalog figures. I think it's clear that no one is "stealing" someone's images. Those images are from an old Sigma catalog and have no commercial value. I'm reproducing the pictures here only to serve the members of this forum. I think it fits well the concept of "fair use."

No, I am not the poster who scanned the manual. As there is water mark on every single image, I am concerned if the person who scanned these image is happy to let us upload and post them here(without any reference to the original post). That is why I include the original link here.

Thanks Gerald. I have the 200mm f4 but often wondered how many lenses were in this range.

Welcome back btw! Wink

I agree with Calvin,if we "borrow" images it would be nice to reference the one who first posted them.I know from experience it takes a long time to scan a catalogue...give credit where credit is due. Very Happy

I agree, but the credit is implicit: there is a name that appears on all pictures. It is the name of the person who copied the Sigma booklet, I suppose. But I do not know if that person had permission of Sigma to copy the booklet.

Very Happy I do see your point and hope you see mine, an extra few words does not cost much to give credit where credit is due.To be honest I did not see the water mark until you pointed it out....it would have added to the work load of scanning the pages. Wink

Whether or not he had permission is beside the point in this case. I am only mentioning that fact for others who will read this and perhaps take on board the above suggestion, to give credit where credit is due.
If they chose to post others efforts via a link or post images not their own. In this part of the forum,as its only new there will always be teething problems.
I honestly thank you for sharing them,it shows you are willing to participate on the forum.

When this thread:

http://forum.mflenses.com/sigma-xq-scalematic-135mm-f1-8-t73282.html

went up the other day on the MF Lenses board, I immediately commenced searching for the sort of data Gerald very kindly has posted above. Unlike Gerald, I was insufficiently skilled to find the data he generously has made known to everyone here. Even after calvin83 posted links to the Chinese sources, I was unable to overcome the language barrier. I confess I neither speak nor write Chinese, and I'm unable to read Chinese. I did use the translator, of course. But its English translation of the Chinese writing is cryptic at best.

How Gerald was able to overcome all this I do not know, but I have two observations:

*I'm most grateful to Gerald for posting information which otherwise, for me, would have remained hidden

*I clearly need to work much harder in order somehow to break through the language barrier I personally face. I'm convinced other lens data treasures lie just out of reach on Chinese websites I'm unable to decipher or penetrate

Guardian you make the most valid point,there is so much out there that we don't know about because we tend to stick to our own little part of the internet.Mainly because of the reason of language differences, especially for us English speakers who only know English Smile Both Calvin and Gerald have opened the door.
