High contrast and excellent image quality are made possible in all shooting ranges. This macro lens is ideal for digital SLR cameras as well as film SLR cameras.Reduces flare and ghostThis new medium telephoto macro lens employs a new design concept for digital SLR cameras. Its new lens power layout produces an excellent optical performance and also reduces flare and ghost. This new lens is designed to reduce the influence of harmful light caused by reflections from the digital image sensor.An easy to use 105mm medium telephoto lensMACRO 105mm F2.8 EX DG lens is very suitable for taking pictures in nature and it enables to use of natural light conditions or flash.The greater working distance of this lens is very advantageous when taking the picture of a flower among the branches or an insect. You do not shake your subject when you want to take its precise details without blurring by using a tripod.The narrow angle of view is a great aid for simplifying backgrounds and shallow depth of field makes it easier to handle the composition. This lens would have an equivalent field of view of a 178mm telephoto macro lens on a digital SLR camera (when used with the SD10).Minimum aperture of F45 Depth of field of medium telephoto macro lenses is generally very shallow; however, Sigma, Canon and Konica Minolta mounts of this lens have a minimum aperture of F45 (or F32 for Nikon and Pentax mounts) for incredible depth of field.Screw-in lens hoodA screw-in hood is included, for convenient use of circular polarizing filters. It is possible to attach an 77mm filter in front of the lens hood.Dual Focus (DF) system This lens also incorporates a Dual Focus (DF) system that is designed to make the lens easy to hold during auto focusing.

 "Superb Quality" 2010-06-24
By P. Jenkinson (Manchester)
This lens is just brilliant. The clarity of the produced images is superb.

It can sometimes be difficult when using it hand-held, but once you figure out the settings, you will be producing excellent results.

I found that setting my 450D to fully automatic often produced images with very shallow depth of field, so now I use Ap priorty and set the aperture to around F8 ro F10.

The macro capabilities are far better than I had hoped, and this lens should be a part of any photographers kit.

i am just an amateur, but i am highly delighted with the sigma. first of all i checked out the nikon 105mm as i believe you get what you pay for, but the extra cost just for vr didnt add up, also in macro vr doesnt help that much. so use a tripod or take more shots and pick the best one. anyway as for the lens its briliant with crystal clear images and deffinately worth the money

 "Good starter macro lens" 2010-03-05
By Darren Simons (Middlesex, United Kingdom)

I bought this macro lens as I wanted to do some basic macro photography using a full-size sensor.. Firstly I can definitely recommend that 100mm focal length is ideal for starting at macro - 50mm is just too wide (probably more use for portraits) and 150mm is just too expensive.



This Sigma lens is solidly built and certainly doesn't feel plastic at all - it's part of the EX range which are the top tier of Sigma lenses (easy to spot by having a gold ring at the end of the lens). Focussing is sharp and as a keen amateur I certainly can't see any shortcomings in this lens in terms of quality (f2.8 is certainly wide enough for me as even at that aperture I can throw the sharpness on macro shots very easily - I actually found I was using f4 most the time as the sharpness was falling off too quickly so focus has to be spot on)



There are a few things I don't really like about this lens though. The auto-focus is quite slow (especially when compared to the USM Canon equivalent, albeit quite a bit more expensive), and the collar which is used to select auto or manual focus is quite clumsy and just doesn't feel right. That said for most pure macro work you're best off using the manual mode and once in that setting the control is pretty good.



My other complaint is that if you put a UV filter on you can't put the cap on - this is because the cap fits the inside of the front of the lens in a slightly different way to most lenses... easily rectified with either not using the UV filter (which is fine since the front of the glass is set a long way back from the front of the lens so is difficult to damage) or buying a suitable cap (prob £10).

Nikon 105MM AF-S VR II F2.8D Micro Nikkor Lens

Buy Cheap Nikon 105MM AF-S VR II F2.8D Micro Nikkor Lens


Buy Low Price From Here Now

The VRII function minimizes camera shake, allowing photographers to shoot hand-held at as many as 4 shutter speeds slower* (at near infinity to 1/3 life size) than would otherwise be possible, assuring dramatically sharper images. A Nikon Extra-Low Dispersion (ED) glass element delivers superior optical performance for both digital and 35mm photography. ED glass minimizes chromatic aberrations, contributing to improved contrast and resolution performance. The incorporation of Nikon s exclusive Nano Crystal Coat technology further ensures superior optical performance by virtually eliminating internal lens-element reflections. Internal Focus (IF) provides fast and quiet auto-focusing without changing the length of the lens, retaining subject working distance through the focus range. Non-Rotating Front Design provides for more convenient use with circular polarizing filters and R1C1 Wireless Close-Up Speedlight System. Provides continuous focusing from Infinity to life-size (1:1), offering extra working distance in demanding conditions. The Silent Wave Motor (SWM) enables fast and quiet autofocusing, and quick switching between autofocus and manual operation. (M/A and M) The nine-blade rounded diaphragm opening makes out-of-focus elements appear more natural. 62mm filter attachment size. Included accessories: 62mm Snap-on front lens cap (LC-62), Rear lens cap (LF-1), Bayonet hood (HB-38), Flexible lens pouch (CL-1020)

 "Brilliant Macro lens" 2010-05-03
By L. Otto (Surrey, England)
Macro lenses tend to be put in the "Special-purpose lenses that I won't need because I don't do that specific type of photography" category without much thought, but this is a big mistake because if anything, the macro functionality seems like more of an useful addition to an already-great telephoto lens. Let me explain:



Build:



The 105mm VR lens is solid. It's one of Nikon's best built lenses. From front to back it is solid metal. The focus ring is wonderfully fluid, and yet has a damped enough feeling to know it will resist even the most penetrating of dust and moisture. The focus index is useless, don't use it. When you're doing macro work all those equations go out the window any way. At the rear of the lens, it is rubber lined so that when you mount it on a camera it creates another seal. Looking at it closely, the seal is strong but don't rely on it to hold up against everything. The lens hood is plastic, and about the length of the lens itself. I never use it, reason being that it doubles the length of the lens, and your effective working distance is that much shorter before you scare away bugs and insects, just use your hand to remove stray light if you really need to. All focusing is done internally so that the lens never extends when focusing, and the SWM motor means that it hardly makes a sound, good for not scaring little critters.



Optics:



It's no secret to say that Macro lenses have some of the clearest, sharpest, most precise optics around. In fact, there is basically no fault with this lens, optically. You will find that due to it's flat-focusing nature, in-focus objects are sharp across the entireframe, even at wide-open apertures like F/2.8 Speaking of which, this lens will only ever be F/2.8 at infinity focus, as you get closer, and eventually up to 1:1 focus, the minimum aperture increases past F/2.8 This is no mistake, and no fault with your lens, it's a simple optical trick that all (yes, all) macro lenses need to do in order to do what they do. You won't get flare with this lens, and ghost are very well controlled until you are shooting directly into a large light source, in which case the smallest amount will come in to play. The front element is smaller than the filter diameter, which means that even filters with a very large, thick ring will not cause you any vignetting. Speaking of which, even at F/2.8 vignetting is not a problem at all on DX and very slight on FX. This is normal.



Features/Performance:



This lens, according to the manual features VR II technology, although the VR icon on the lens barrel is red, and not gold as the new VR II lens models have. I don't know or care which it is, because it works perfectly. There are a lot of reviews saying that VR is 'nearly useless when doing close macro stuff' and to 'turn it off to save battery'. I'll admit the VR isn't as effective as when used at infinity focus, but it still works very well at 1:1 and really can make the difference, I assure you. Don't be put off. As for the battery-draining, a close friend of mine says that the VR on this lens eats his D200's battery alive, and he can literally see the bars going disappearing with use. On my D3s, it is not a problem, it hardly has any impact on the battery level at all, and I can comfortably use it all day long on a full charge, and have plenty for the next day.



Autofocus speed is good, but it's hardly stellar. This is not a fault with your lens, all (yes, all) macro lenses have quite poor (in comparison to $4000 zoom lenses) focusing due to the extreme range in which they have to work. This will often lead to 'hunting' which is where the lens struggles to find the focus point and moves back and forth between near and far. Fortunately, the lens does have a focus lock but this won't help you in macro as it locks way past where macro really begins. What will help you, however, is that the lens has a full-time manual focus override on that beautifully large focus ring, meaning that you can have the last say, every time. It works without failure, and it's a useful feature.



Moving away from macro, this lens can be used as a stunning prime-telephoto lens for portrait work. The bokeh is nice, but not as good as an 85mm 1.8 lens, against a plain background however it is much sharper and with less distortion, and obviously VR helps in every situation.



I hope this helps

 "Excellent" 2010-04-02
By M. Potter (Surrey United Kingdom)
Unfortunately the version Amazon sent me looked like it was second hand (lens barrel dirty, front and rear elements dirty), so I sent it back for refund and got another from Jessops. But don't let that put you off, because this is an excellent lens.



As others have said this lens is wonderfully sharp and doubles as both a macro and walkabout lens for portrait and other uses. Fully compatible with both FX and DX format, on DX cameras you will of course get a 1.5x boost in magnification compared to FX. It's expensive, but it's top quality glass and a good investment in my view. If you have a DX format SLR you will have a lens which will upgrade to FX if/when you decide to. One day I'm going to go for a D700 (or whatever semi-pro FX SLR Nikon is selling at the time), so when I do the 105 will step up with me without me having to pay again.



A nice fast f/2.8 aperture, although you may notice the camera body showing a smaller aperture (higher f/number) when working in macro ranges - apparently the effective aperture at macro distances decreases (by 2x if working at 1:1 magnification). This is the law of physics and applies to all macro lenses, it's not a defect (and besides, you're unlikely to be using wide apertures when taking macros anyway, so nothing to lose sleep about).



In normal ranges the AF is very quick on my D300, but this is with the limit switch on (which limits AF from 0.5M to infinity, therefore excluding macro). I found that at macro range or at normal range with the limit switch off that the lens can sometimes hunt. At macro I'm mostly working with manual focus anyway, so this isn't a problem for me. If you're using the reach of the 105 for fast action shots just keep the limit switch on. Simple.



Bokeh on this lens is lovely - I've only had it a week, but have already taken some wonderful flower macros with it, with beautiful creamy bokeh. The lens is very sharp but at macro range the DoF takes some getting used to - the field of view changes at macro range with just minor movements of the lens (breathing), but given the results you get I'm prepared to live with that.



It's a big lens, heavy and fairly large for a prime, but doesn't look out of place on my D300 (and well worth the size/weight inconvenience IMO). It's very well built, and looks like it would stand up to the roughest of treatment. More pro-like than the other (DX) lenses that I have. I haven't tried it on smaller SLRs, but I expect that on something like a D40 or D3000 it would make the camera feel very front heavy - my advice would be to try it out in person on the high street and see how you get on.

 "An Excellent Lens, but read on if you are confused about VR and VRII" 2010-01-21
By Gundog (Oxfordshire, United Kingdom)
I ordered this lens from Amazon as it was advertised as a VRII in the product description. Its actually labelled on the box and on the lens as a VR lens, however the supporting documentation inside the box does refer to it being the latest VRII technology. This confused me as I thought Amazon had initially sent me the wrong lens.



Now the confusion is over, I'm keeping the lens, however have not yet had a chance to use it.



I hope this makes things clearer for other buyers, as my initial disapointment is now resolved.



I'm massive fan of Nikon lenses, so am sure I wont be disapointed with the quality.

 "The best lens on my kit - 105mm f/2.8 VR" 2009-12-30
By A.F.B. (@UK)
This is simply the best lens that I have and I do have good fast glass... excellent bokeh and colour rendition, headshots with this one are really tack sharp and the macro is stunning (provided that you have good light). The only lens that might be better for headshots than this one is the 85mm f/1.4 (which is in my list but no funds for it yet), but this one is definitely an outstanding piece of engineering.



If you are serious about photography and use Nikon, this lens should be on your kit. It has replaced the 24-70 as the "always on" lens on my D300.

 "Excellent but not cheap" 2009-11-12
By Greg Ó Donnabháin (Cambridge, UK)
I bought this lens after searching through many reviews including those on this site as well as managing to borrow a similar Sigma macro lens. My experience to date with this Nikkor micro and the D300 is only positive - the quality is superb both for portrait work and 'traditional' macro work. Like most things, it pays to experiment to get the feel for the lens and its capabilities - one of the many beauties of digital is that it allows you to do that free of charge. It is not cheap but my advice is to do what I did and save until I could afford it rather than buy a cheaper model and then decide that you want to upgrade. It lives up to my previous very good experience of Nikkor lenses - beautiful workmanship. If you do decide to take the plunge I am sure that you will be extremely satisfied with the results.
