Just got a new[ish] Nikon, looking for lens suggestions

<p>I am now the proud owner of a Nikon D90 with a Tamron 18-200 Zoom lens Don't get me wrong the lens isn't bad per se, but it's not really sharp or fast enough for portraiture, which is mainly what I'm looking for. Can anyone suggest a good, cheap lens for such a purpose? Any older f mount lenses work too, they don't need to be autofocus, though preferably they should be AI</p>

<p>Thanks in advance!<br>

<p>So much in picking a portrait lens is comfort level with working distance. It can be done effectively with any good lens in the 35-135 (FX equivalent) range. Under 35, some care needs to be taken to avoid distortion, over, and even with 135, you can get some compression. I have the 50 1.8 and it is quite a good all "arounder". Have gotten good informal portraits at close mid range, 6-10 feet. With the D 90 it will effectively be a 75, so better for portrait than street. Good luck with your decision!</p>

<p>The 50mm f/1.8 is a pretty good start - the AF-D is small and cheap, and probably worth it over the AI lenses for convenience of having working metering - the optical formula goes back to the manual focus f/1.8 50mms. The AF-S version costs twice as much and is twice as big, but it's appreciably better optically. Neither are extortionate, and would make a decent short portrait lens; they're both very sharp stopped down, and they'll both isolate the subject at wider apertures much better than your zoom. If you're really worried about cost and size, the 50mm series E is almost a pancake (the AF lenses have the front element heavily inset) and, coatings aside, is the same formula as the AF-D - I got one for when I'm space limited, since it barely makes the camera thicker than the grip.<br />

<br />

For a longer telephoto there's the 85mm f/1.8, but the AF-D version, while very sharp, has (I believe) quite ugly bokeh. The AF-S version is better, but costlier and has quite a lot of LoCA. The Samyang 85mm f/1.4 isn't bad at all if you can live with manual focus, but I've currently got my eye on the new VC Tamron 85mm f/1.8. Longer than that really is quite long on DX; I quite like the 135mm f/2.8 AI (and relatives) on an FX body, but I suspect you'll find it longer than is convenient on a D90. Still, I'd start with the 50mm and work from there when you decide what focal lengths you need. That's one big advantage of the zoom - at least you can experiment with cropping!<br />

<br />

Good luck, and welcome to the dark side.</p>

<p>Just to expand on what Peter said, the conventional (read: from people trying to sell lenses) advice for a portrait lens is to aim in the 85mm-135mm range on full frame. That's partly because the conventional distance from which to shoot a portrait is about 15', since if you get much closer you start getting big noses and small ears (the perspective difference between the front of the head and the back is more significant), and much farther away you get a "flattening" effect (reduced 3D distortion) - supposedly people "remember what people look like" as though they're at this distance, so it looks natural. That said, unless you go to extremes, that's a very rough guideline - many less conventional portraits are taken with a wide angle, and some (including me) often use a longer telephoto for some portraits because it gives more control over the background at the same aperture; this is common for model shots, and it's convenient for candids. You can tolerate qutie a lot of apparent perspective distortion before it gets intrusive, and even then some people like the effect.<br />

<br />

On a full-frame camera, an 85mm lens used at 15' distance puts 15'x36mm/85mm = 6.3' on the long edge of the frame (36mm). For a 135mm lens, it's 15'x36mm/135mm = 4'. So an 85mm will just about fit a person full frame in portrait framing or an upper body shot in landscape (replace that "36mm" figure with "24mm"). A 135mm will do an upper body in portrait, or head and shoulders in landscape. 100mm-ish lenses are popular as between the two. But as I said, the 15' is an <i>extremely</i> rough guideline.<br />

<br />

On a crop sensor like the D90, you've got a sensor 2/3 of the size in each direction compared with full frame, so you'll see 2/3 of those distances - or the equivalent of using a lens 50% longer on the full-frame body. 85mm on full frame looks like roughly 57mm on a DX body; 135mm on full frame looks like 90mm on DX. So you get pretty close to the shorter and longer conventional telephoto lengths if you use a 50mm and an 85mm lens on the D90. Whether you agree with the conventions of what a portrait should look like is another matter.<br />

<br />

The other reason the 85-135mm range is suggested is because fast apertures (for background separation) in those focal lengths aren't ridiculously expensive, so camera companies can reasonably sell them to you and you'll see a difference in what the lens can do compared with a budget zoom. An 85mm f/1.4 or a 135mm f/2 is a chunky lens, but not ridiculous or excessively specialist. A 200mm f/2 is <i>huge</i> (and something like a 400mm f/2.8 is worse). At the same aperture, longer focal lengths lose the background better, so an 85mm f/1.4 (or f/1.8) makes the background disappear more than the equivalent 50mm lenses, and they do the same relative to 35mm lenses, etc. If you want to blur the background, the 85mm makes a substantial difference - but it also means you'll have to stand a long way back for group shots.<br />

<br />

50mm lenses tend to be cheapest, so as others have said, I'd start there and see how you get on. If you want to blur the background more, an 85mm is the next obvious step. Good luck!</p>

<p>The D90 does not support metering with the old MF Nikkors, which you may know already. If that is no problem, you could try the Nikkor 75-150 f/3.5. It might be a little long on DX, but it is very cheap (should be able to get a nice copy for $100-$150) and creates nice separation. The 85mm 1.8G is quite a bit pricier but works well on DX. There is also the 105mm f/2.5, but I think the 75-150 will give you more flexibility.</p>

<p>Just to take the contrarian point of view, I did portraiture for decades. 90% of the time in a studio using a sturdy tripod and multiple strobes. The lens' max aperture was of almost no consequence at all, and a little lens softness, or the judicious use of soft focus filters, decreased retouching costs and made the mother of the bride look 10 years younger, which in turn made me out to be a hero. Just sayin'</p>

<p>I accept the "aperture doesn't matter for portraits" thing - if you shoot at f/1.8 from anywhere close, you'll have bits of the subject out of focus too (which you might want artistically but probably not in the conventional sense). It's one reason that longer lenses can help - you can use a smaller aperture to keep the whole subject sharp, but a distant background still gets blurred. Still, it depends where and what you're shooting - I've taken a lot of candids (I'm not a professional) in places where the background is very messy and out of my control, and blurring it was helpful. If you paid for a nice studio background, you might not want to have made it invisible! Still, you can always stop down a faster lens; making a slower lens faster is tricky.<br />

<br />

I've also heard the "softness is good for aesthetics" thing before; indeed, several people sell filters specifically to achieve this, and the old "vaseline on the lens", or a stocking stretched across the front, wouldn't happen if it didn't sometimes help. Generally it's about reducing lens contrast so wrinkles aren't so obvious. If you're going to use images straight out of the camera, this is probably still good advice. Still, ideally things like the eyes and hair should be sharp, even if the skin isn't contrasty, so doing some editing after the fact can be beneficial even if you're not going the full airbrushing route. I find it easier to soften an image in editing than to sharpen one - apart from anything else, sharpening adds noise, whereas softening reduces it, and sharpening also tends to add haloes and make bokeh look worse if you're not selective about it. So there's still a lot to be said for starting with a sharp lens, even if you're going to throw some of that sharpness away.<br />

<br />

But having a slightly soft lens is better than not having a lens at all, so don't sweat it. I'm just trying to justify to myself how much money I've spent on glass over the years!</p>

<p>Just my $0.02, but I would not constraint myself with an AI lens (manual focus, no metering) with a D90. For street and general purpose, I would suggest the Sigma 30/1.4--just an awesome DX-mount lens.</p>

<p>Wrt portraiture - are you talking about indoors studio portraiture? If so, nothing wrong with your Tamron 18-200mm. That kind of work requires a steady tripod and perfect lighting. </p>

<p>If an 85mm f/1.8, I'd strongly recommend the 85mm f/1.8G - some may find it long for DX, I quite liked the FL, whereas I never like the perspective of a 50mm on APS-C for portraits. I'd start checking with the Tamron which focal length you feel most comfortable with, and then make a shortlist of primes in that range.</p>

<p>i find 50mm on DX a little short for portraits. i would consider the Tamron 60/2 macro or the Cosina Voigtlander 58/1.4 as dedicated portrait lenses. 85 could work, but is a bit longish on DX. One of the best portrait lenses for DX is the non-OS Sigma 50-150/2.8, worth picking up if you can find a used copy. that lens is great for event shooting as well. </p>

First, let me say Congratulations! on buying a Nikon D90. It is a fine camera, and with a little care in use, will serve you as well as many newer (and more expensive) Nikon models. I own two, as well as a D700, I use my D90s regularly and am always pleased with the results I get.

 

 

If you want the cheapest-best option, go for the Nikon 17-55mm kit lens. On the whole it performs well and I have even seen pros using it for their assignment work. Family friends recently had their daughter's wedding shot by someone (pro) who usedD90s and this lens for most of the shooting, and the results were exceptionally good.

 

 

If you prefer a prime lens or want a better fixed length for portraits, take a serious look at one of the Nikon D 50mm lenses. A secondhand D lens will give you approximately a 75mm outlook. If used carefully and with an appropriate lens hood and a clean Nikon UV filter, it is also a mean on the street performer allowing you to stay at a discreet distance from your subjects, which can also be a positive factor in portrait shoots` The 50 will let you print easily to A4 or larger print sizes.

 

 

Best of all, prices on used 50s if bought secondhand (ideally from a reliable seller such as a long-established photo shop) will please you without emptying your wallet or draining your bank account.

 

 

It's very much a matter of horses for courses, as Australians often say.

<p>printing sizes have nothing whatsoever to do with choice of lens. in fact, a shot taken with <em>any</em> lens on the D90 can be printed at A4.</p>

<p>Well yes, but the larger the print, the more you'll see optical limitations. I imagine some wall-sized prints might start to look a bit ropey from the 18-200 - but I don't know how many people do enormous prints these days, and I worry far more about pixel peeping on a computer. And of course it's not the size of the print that matters, it's how closely you're going to look at it.</p>

<p>The 18-200 was fine at every focal length (although you HAD to stop down one stop above 135 to get usable results) on my D50 at 6MP.<br /><br />When 12MP was the norm with the D90, even back then, above 135 it drove me crazy and I sold it.<br /><br />Printing below 8 x 10 or never cropping? It might make you happy (same with 18-300). Only viewing on the internet and screens? I think it would be just fine.</p>

<p>I had a similar experience with the older 28-200mm zoom - which was very good on film, very good on a D700, and awful on a D8x0. I've just traded it in, slightly reluctantly since it was my first Nikon lens. It was also much better than the Sigma 28-300 that I used to use on an Eos 300D (which was weak even at 6MP). Still, I'd start with the lens you have and worry about Nikon Acquisition Syndrome when you need to. Look closely enough at any lens and you'll find imperfections.<br />

<br />

It's true that an acceptable lens at low resolution may not be acceptable at high resolution. I don't believe that "nobody makes large prints" is a reason not to need resolution, though - yes, you won't see much in a small on-line thumbnail, but it's now really easy to zoom in to 1:1 and scroll around a large image on lots of photo sharing sites. Arguably, especially for those of us with imperfect eyesight, this makes it much easier to see tiny imperfections. "The internet" is not 640x480 anymore.</p>

<p>not necessarily. really depends on the shot. i concur that the 18-200's optical flaws might reveal themselves sooner rather than later with a big print, but the point i was trying to make was that a 50mm prime is really no better or worse than most lenses for enlargements. ive printed 16x20 and even 20x30 with a 12mp sensor, so it definitely can be done. but if you're going for huge prints, the gold standard is a high-MP FX body. </p>

<p>Of course a full frame sensor will outperform an APS-C sensor almost all the time, the problem is the money. I'm assuming that a prime lens will be sharper than the equivalent 50mm on a 18-200 zoom, in the case I don't want the image to look soft focused</p>

<p>Apologies for the diversion, Spencer. A 50mm prime at a moderate aperture (say somewhere between f/5.6 and f/8 depending on the lens) is likely as sharp as anything, especially on a relatively undemanding body like the D90. The 18-200 shouldn't be awful at 50mm and f/8-11 kind of range, to be honest. I'd warn you that wide open, particularly the older Nikkor 50mm primes are quite soft as you move away from the centre - and the 50mm f/1.8 lenses are pretty dodgy if you're expecting sharpness (or at least contrast) at f/1.8. Stopped down they sharpen up quickly, though - and of course the zoom can't do f/1.8 at all. I just didn't want you to compare 50mm at f/1.8 with 50mm at f/5.6 and be disappointed!</p>
