Question: I want to shoot jewelry. w the 100mm Macro I have now, the depth of field if such that only part of a ring will be in focus. Will this lens help?
Document: Great little lens. One thing to keep in mind if choosing between this and another focal length, you have to get much closer with a 40mm, say, versus a 100mm to get the same &#34;closeness.&#34; But because you're doing this physically, versus optically, you're depth of field is going to be ultra-shallow. This was one disappointment, that I couldn't even get a  whole insect in focus.
Beautiful lens - My go to lens when I want to go out and shoot with one single lens. I am very happy with it.
Fantastic lens!! I originally purchased this for the detail shots during weddings (ie. "ring" shot, table set ups, flowers, etc) and newborns, but I think this will be one of my new go-to lenses for everyday portraiture! It creates the most beautiful sun flare which coincides with my person shooting style when I shoot into the sun, and generally is just fantastic! Great price for this lens!
While everyone says you wind up using manual focus/camera moving for macro, being able to let the AF get you "close" before fine-tuning in manual was a huge help for things like butterflies when they might only be in one spot for a few seconds (when compared to non-electronic macro tubes).
Focus was off on about 55% of photos. For indoor use a definate NO. Frankly anything important should not be shot with it. Worth the price definateley but if you want to make money off of this lens and the type of photography needs to be quick, dont use.
you can realy get in close, the ability for this lens to achieve close up images is superb. I was able to fine tune it to limit the in focus section to just a part of the cross and a couple of lines of scripture.I later used it to take a close up picture of my daughter's eye while she was focusing on a picture of a rose from a computer screen and the reflective image of the rose in her eye came out great.
According to Nikon, this is a new design and it really handles well and balanced with my Nikon D5000. However, owner should have the supplied HB61 lens shade mounted to protect the lens as the front lens element extends out of the barrel at nearer to closest focusing distances typical of micro lenses.Auto Focusing with Nikon's AF-S technology is silent, smooth and accurate, while the manual focus ring is tactile but responsive for manual override focus at close range.
If your dSLR has low noise ISO 1600-3200 sensitivity, close up photos could be taken at moderate handheld speed of 1/20s - 1/60s without flash and under natural existing indoor light condition with some practice.Noted that at close distances my Nikon D5000 appears to select program aperture at f3.2 to f4.2, on auto ISO 1600-3200, to optimize depth of field, which seasoned users of micro lenses would know is critical at close range, awesome!
I purchased this lens because I wasn't sure if I would like macro photography, and didn't want to spend a fortune to find out. Well, I now love macro shots! The lens is fast and the images are tack sharp. It works wonderfully with my D7000. You can never go wrong with a Nikon lens.
I love this lens and it is perfect for macro photography. I photograph baby jewelry and hair accessories so it gets the job done for exactly what I need. At times, I wish that I had ordered the 60mm in order to get closer to the subject but for the price, I had to go with this one. I highly recommend it unless you have the money to get a better lens.
Answer: Depth of field is more of an aperture issue than focal length.  Shoot at anything F16 or higher and you will have plenty of depth of field with this lens or your 100mm.  This one is probably the cheapest priced Nikon micro AFS lenses.  I have no problem taking 1:1 close ups although a tripod and remote release help if I'm not using flash
