Sigma, are you listening?

A near perfect camera system combining the features of portability, use-ability, quality of design engineering, quality of build, quality of photographic result, and in the case of the A6000, very good value also.

What's to complain? Can I be allowed one little niggle (earning 4 stars not 5)? Yes? OK, there is no 24mm (35mm equivalent on full frame) that is good value, compact, with great performance for this system!?

Who woulda thunk it? The most commonly used fixed focal length lens in the world (for good reason!), and none exists for this format?

Jim Rollins has done it again. The 6th Extinction is a blend of core characters that we have come complimented with new antagonists and protagonists that we love, hate and share empathy.

As in all Sigma novels, history and science blend together to create the perfect read.

I use the SPIRE to track my daily activity. I find it very helpful with monitoring changes in respiration rates during tense and clam moments.
The SPIRE provides positive feedback following activity ! A great but small coach !
Any8 issues ae addressed by a kind & "fun" support staff!

I bought this lens and A Sigma lens. The glass in this lens is significantly more accurate.

Excellent read for people who want to work on their listening skills.  Recommended for anyone involved in work where you counsel or coach others or anyone who wants to connect more deeply to others by listening.  Following principles presented here you can become a better listener to your spouse, your kids, your friends, your teammates, your colleagues, and even to people you don't know well.

The music may not be your first choice but consider first your motivation to listen.  It is to heal and to grow mentally and emotionally.  This does not require anymore of you than listening.  It does not require analysis, or concentration, just awareness of the music you are hearing. Ive noticed, after listening, that running water sounds louder, and there is gurgling sound as the water goes down the drain that I never noticed before.  I experienced focused attention without the intention to focus.  It was money well spent for me.

It's an amazing lens, however, I had a problem with the AutoFocus (which has been mentioned in several forums over the Internet) and it happened to me as well.  I send it back to Sigma and they fixed it.  I had to incur in additional charges which doesn't make me very happy.  Once again, as far as the lens go, it has an amazing range and the luminosity is what you'd expect on a lens that range and that size.

A true pleasure to use this excellent lens.  This is my second macro lens.  The first is also a Sigma product.  I find this lens easy to use and capable of producing excellent macro photographs.  IQ is superb.  Operation is smooth and easy.  I also appreciate that it can well be used as a medium range telephoto lens, in addition to its macro abilities.  I definitely WOULD recommend this lens to a friend.

Thank you Sigma!

Another well-written, insightful book by Steve McConnell.  It makes the case for not only process, but also for a more professional attitude by programmers and the industry in general.  Some of his points will be  familiar to those who have read his other books, like Software Project  Survival Guide, or his columns in IEEE Software.  The book offers a good  look at where the software industry is headed from somebody who knows.

The sound is great i would recommend running a calibration with your receiver because it let me know that i had my sub to loud for my speaker during the test

Good price, but for the Sigma alone is $144, so I decided to return it.

I suspect that "Black Swan" has been in the lexicon of statistics for a while. But, this book seems to have raised awareness to a global level. I like reading the works that influence the thinking of the world in a fundamental way. I think this may be one of those books. I suggest reading Fooled by Randomness, The Black Swan, and Antifragile in their order of publication to get the most out of them. They are worth the time.

Sigma has given us the 70-200 for the digital age. With the 1.5 crop factor, a 70-200 just can't go quite wide enough sometimes when you are in a more crowded space. The Sigma weight about half what the 70-200 does. HSM for quick autofocus, works on my D40. 2.8 allows shooting in low light, and throwing the background out of focus. The lens cap is edge-pinch, meaning you can't get it off without taking off the hood. I've taken to replacing Sigma caps with Nikon center-pinch designs. I wish Sigma would fix this - the small things add up. They do include a nice carrying case for the lens, though. My only wish is for image stabilization, but I knew that when I bought the lens, so it's not Sigma's fault. Overall, a keeper.

Good science. Great character development. Believable plot. I always love the exotic places he takes the Sigma team to. Most of them I would love to visit but without the bad guys chasing me. I highly recommend this newest Sigma adventure.

For those who are taking their sense of mindfulness to a practice level.  Take a moment here and there to listen to the stillness self creates a want to do it more.

We recently changed to the new sensor and we are really happy with the clear images.
Tom from Masterlink did a great job teaching the assistants how to use the new system. Thank you so much Tom!

Warnings are being sounded and need to be heeded.  Not technology bashing.  Makes some very astute observations that are data driven.  Very thought provoking.  Above all, it is very readable.
