Micro-Nikkor AF 70-180mm f/4.5-5.6 D ED (front) and Sigma AF 150mm f/2.8 APO EX HSM macro DG D (back); both tripod collars have an RRS plate attached.
The Micro-Nikkor AF 70-180mm f/4.5-5.6D ED is a unique lens - it is the only true macro zoom lens around with a max. object magnification of 1:1.3 (the 6T close-up lens is required to get to 1:1). In terms of useability it is the only macro lens which allows precise framing (if framing and not precise magnification ratio is of significance) without having to change working distance and refocus. This is an advantage in the field especially when working from a tripod since framing and focusing can be achieved without having to move the assembly back and forth. Attaching an Arca-Swiss-type plate to the tripod mount makes the system a lot more stable - the original foot is a tad short.
The Nikkor has a rather long focus path (roughly 200 degrees) which is nice for precise manual focusing. On the downside the AF (via the slotted drive screw operated by the camera) is relatively slow and noisy. A focus limiter helps to reduce excessive focus hunting in non-macro situations.
The image shows the lens focused to its minimum focus distance of 0.37m (the working distance then is a scant 11cm); at the longest focal length, this equates to a 1:1.33 magnification ratio (1:3.21 at 70mm). When focused to infinity, the front retracts almost completely into the lens barrel. One characteristic of this zoom is that the effective aperture doesn't change as a function of the focus distance - probably because the focal length is substantially shortened in the process of focusing closer (which is indicated by the close working distance); I read somewhere that at the 180mm setting and closest focus distance, the focal length is around 90mm. As I said, it's a unique lens.
The Sigma is an IF (internal focusing) design and loses about 1.5 stops when focusing from infinity to its closest focus distance of 0.38m (at which point the magnification is 1:1 and the working distance about twice that of the Nikkor). The HSM makes focusing virtually silent (though not necessarily quick - but the three-stage focus limiter helps but takes getting used to (full-range, 0.52m-infinity and 0.38-0.52m)). The Sigma tripod collar is removable - a big plus; it's also quite sturdy. Unfortunately, due to the IF design, working off a tripod when trying to maintain framing is an exercise in frustration - a macro rail is an absolute must. Really too bad that the lens that works great on a tripod (the Nikkor) has a weak tripod mount (that isn't removable to add insult to injury) whereas the one that drives one nuts on a tripod (the Sigma) has an excellent one.
The Sigma is a tad shorter than the Nikkor but takes 72mm filters to the Nikkor's 62mm. The Nikkor weighs about 1kg, the Sigma is about 100g lighter.
The Nikkor has an unusually low distortion for a zoom over the entire focal length range - the Sigma has virtually none. Optically, both lenses are excellent - with the Sigma taking the crown.
For general (non-macro or non-close-up) shooting, the Nikkor is a slow variable aperture zoom whereas the Sigma is a fast (f/2.8) medium tele with a very nice bokeh. The Nikkor is no slouch in terms of bokeh either - but has the disadvantage of being between 1 1/3 to 2 stops slower.

March 2013: Realizing that most (of the little) close-up work I shoot can be accomplished with either lens (and me not really utilizing the strengths the zoom offers in that aspect because I mostly shoot handheld) as well as finding that the prime is more useful to me in general shooting (now that I own the 70-200/2.8 AF-S VR), I decided it was time to part with the 70-180 that I owned for about 12 years. It's an excellent and unique lens, but that's not enough reason to keep owning it for me.
October 2015: traded the Sigma 150/2.8 for its successor, the 150/2.8 OS. Significantly larger and heavier but optically as good as the non-OS version.
I will refocus foreign aid dollars to where they’re needed most. I will cut aid to wealthy countries like Russia, Italy, and China, to put money back in the pockets of Canadians. It’s time for you to get ahead.
Je vais rediriger les fonds destinés à l’aide étrangère là où ils sont le plus nécessaires. Je vais réduire l’aide aux pays riches, comme la Russie, l’Italie et la Chine pour remettre plus d’argent dans les poches des Canadiens. Plus. Pour vous. Dès maintenant.
I have a Lytro camera - the 'light field camera'. You can focus after the image is taken. This is a series of 4 jpeg exports from the same lytro image with different focal points. First is focused on the spider, then the dewy web, then the tree. Fourth is focused on the house. Exports are from the same Lytro image, with jpg exports at different focal points. See and play with the image here:

This is a single capture photograph of a dead Joshua tree. The camera was rotated eight times. Each time, the tree was lit with a different color. The camera was then moved to a second tripod, with a refocus, for the orb. Shot in Joshua Tree National Park, California.
For some reason, my camera outmost refused to focus - despite however many times I tried to refocus it... :(
My Love // Paris #igersParis #igersFrance Valentine’s Day is supposedly about spending time acknowledging and appreciating your love. Regardless of your feelings on the subject, and whether such a day should exist or not when such statements of love you would think should occur on a more regular basis, it is, what it is. Today, after days of speculation I decided to commit myself to my love. It is a plan which I hope will rejuvenate, replenish, refocus, refuel, and restore my love, our love. My love and I lost our spark some months ago, and we have been working at it, but struggling to truly get back to where we were. We had been in such a lovely, happy bubble together wafting along with the wind, way up high above the rest of the world. Life was good, life was great. We were filled with joy and had been for quite some time until one day, one night. It wasn’t our doing, but we lost what we had. Our joy was taken from us and it didn’t take long for things to fade. It’s taking time, but we are getting there; slowly but surely. Today, in order to acknowledge what my love means to me I took what I hope and believe to be another step in the right direction - securing our future for the next few months until the time comes when I hope we will be back on our feet, standing tall and proud alongside each other like we used to. In May this year it will have been seven wonderful years since we started on this journey of ours. Until recently I haven’t been able to see life in any other way than what we have, what we had, what we will have again. As time goes by our relationship matures, twisting and turning with the lessons of life, learning the lessons of love, adapting all the while. I don’t want us to loose, forever, what once was, even though for now, we have. I no longer feel the way that I used to and I have come to accept that. It doesn’t mean that I don’t think about you every night and day, I do, but differently. My heart still beats, faster at times, but no longer for the right reasons. We can work together, we can get through this. We will work together, we will get through this. I know, because we must. Travel is my life, my love. **See you again soon Australia! via Instagram ift.tt/1QBCb8I
This is G, the chef at Monti's on Mill in Tempe, AZ.
While photographing G, he pulled two spoons out of his back pocket. I thought it was funny and captured this image.
A (very) quick editorial photo from a recent outing with some photography friends of mine from Refocus Phoenix.
We had dinner and photographed some food ( just for the fun of it) Because G let us have our own special room I decided to create a super fast portrait of him. Setting up the lights, metering AND the photo shoot happened in 10 minutes.
3 light setup. 1 small soft box for the keylight, 30deg gridspot for an edge light.& 1 background light.

The A List! has settled into a nice niche of wonderful people, clubs, djs, musicians, sim owners, event planners, artists and creators.
But, the best part is that now both Xavi and I have our own resource for the best of the best in Second Life. I just wait to see that orange A List logo pop up and I know it's either going to be an outrageous party, an elegant ballroom affair, live music or a peaceful exploratory evening on a beautiful sim.
Bella Vida has disco night each month. They redecorate the place to reflect the times. It's always fun to pop in on that one.
Dance 4 Life is one of the newer clubs in Second Life. High above the NYC skyline on the rooftop, you can dance your night away in a beautiful, urban setting.
The other night I stopped off at TrueHouse. True to it's name, the house was sweet and fine. I stayed for quite a while... only taking one picture, 'cause the music was so good... I was so chilled.
DJ Benny Klang was at Haad Rin the other night. From Germany, Benny mixed some great tunes for the beach crowd there that night.
Daemon! We always shout when we hit the floor at Derailed on Sub Zero. Along with dj's Ware & Blabbermouth, DJ Daemon Chadeau is one of our favorite noize makers. We always have a great time there.
DJ Tasty was spinning late one night over at Electro Violence. So I hit the tp for a brief break from building. Always a great way to refocus on the build!
WET Builder Robertson sent a tp with a plea that he needed to take a break. Blackhearts club is a favorite for the 80's music lovers. DJ Thalie was spinning and I always love her sets.
Speaking of dj's, I just love DJ Space Grelling. He and Harriet greet everyone with a friendly smile and shout. And his sets are just so fun. I swear I could hang out at alt7 all day long! LOL!
Check out Bay Vista Live Music scene where you might catch Maxmillion Kleene singing his sweet songs with that mesmerizing voice. I stopped off one day, sitting at the table listening.
And finally, for those who need a romantic evening locked in each other's arms, head towards the legendary, Avilion Ballroom.
