I have a Nikon DS3100.  I have now been given two lenses.  Canon Zoom Lens EF 35-80MM TOKINA 28-210MM   I have not yet tried them on my Nikon DS3100 and wondered if they are suitable to use.  Any help would be appreciated.  But please talk in layman terms as I'm not well up on camera and lenses as yet.  Thank you

I've got some lenses of brand X, but I've just got a new camera of brand Y. How can I tell if it's possible to use my lenses on my camera? I accept that I may lose a lot of automatic functionality like autofocus, aperture control and metering when using an adapter to connect the two.

I am looking to add a longer lens to my current zoom (a Tamron 17-50) for my Nikon D300 (but I believe this question is relevant across aps-c lens manufacturers).  There is just one currently in production — the Pentax 50-135 f/2.8 (which is Pentax mount only).  What is the reason behind this? Is there a physical reason why making a smaller DX alternative to a 70-200 is not be possible? I have seen it mentioned that "beyond 100mm the advantage in making dx lenses is gone", but not sure if this is folklore or a genuine restriction.

I have a Canon EOS 550D. Right now I only have some standard lenses, and I'm looking to buy a Tokina AT-X 116 Pro DX II 11-16mm F/2.8. (I love landscape photography and photography in nature in general.) I want to try using a circular polarizing filter, and I've been looking at the Hoya Filter Circ Pol DMC Pro1 77mm. I can see that the "slim" version is cheaper than the regular one, however, I'm not sure what the difference is. Can any of you tell me which would one be preferable for landscape photography? (I found a thread posted about this some years ago but I would like to hear what you guys think, knowing what camera, lens and filter I'm thinking about combining.)  All feedback would be very much appreciated! :-)

This is specific to Canon, but what is the difference between EF and EF-S lenses?

What is the difference between using a motor on the camera body and the motor built into lenses?   Aside from how both compare in terms of speed, what differences would I notice if I use a body with a motor and motor-less lens, and a lens with motor on a body that lacked one?  A comparison chart outlining the various lens motor types would be a great help as high end USM motors for Sigma lenses are faster then their regular versions.

Recently, Nikon announced their , as revamp of the old 50mm f/1.8D. :     The main difference between this new   "nifty fifty" and the almost   decade-old ƒ1.8D is that it has an   autofocus motor inside. This means you   can use it with any current or recent   Nikon SLR. The older lens lacks this   motor and is instead driven by one in   the camera, which cheaper bodies don't   have.   I currently use a Nikon D80 (and I don't plan on changing that any time soon), and I've been considering getting such a lens. Is there any difference between the D and the G lenses when used on a D80? I believe that the D one works just as well, since D80's have internal autofocus motors - is that right?  Besides the autofocus motor aspect, is there any other big difference between them? Since the D is priced at around $120 and the G at $220, should I just get the D?

I am getting a deal on a Canon T3 cam with 18-55mm kit lens and I have choice of one extra lens: 75-300mm f4-5.6 and 55-250mm f4-5.6. I generally like to shoot street, abstract and nature photos and I'm not sure which lens is going to be more suitable to my needs. Are their pros and cons to either lenses given my preferred subjects?

I want to get a filter kit for my D3200 camera. I am looking at a nice one, the only problem is, the thread size on my regular lens is different then my larger lens. Will it work for both of them? If one is 52mm and the other is 58mm so a total of 6mm difference between them.

This is a two parts question  1) Is there a significant reason I should get the Tamron 70-200 G2 rather than the Tamron SP 70-200mm F2.8 Di VC USD?  2) Would getting the Canon 70-200L (first version) be a better purchase then the Tamron in question 1?

I'm reading that a 50mm lens is recommended as a first prime lens for DSLR owners as it's supposed to give a 'natural' perspective, but when used on (most) DSLRs, the view is cropped, as if you were zoomed in by 1.5-1.6x, so it's more of a telephoto lens when used on a DSLR. I've also read however that the 50mm lens gives the same perspective on a DSLR and a 35mm, and shouldn't really be considered to be 'equivalent' to an 80mm lens as the crop factor isn't really a magic focal length changer.  Can someone explain how the image is different from (for example) a 50mm lens on a DSLR and an 80mm lens (assuming 1.6x crop factor) on a 35mm camera?

Should I buy a Canon 55-250mm lens or 70-300mm for my Rebel T3i? I have the basic 18-55mm lens that came with my camera but I need a next step up that's not too expensive.   What are the most common types of photos shot with either lenses? Or what is each lens best for?

I am a newbie to the new camera I just bought. It is a Nikon D5200 it has the original lens that came on the camera a 18-55 lens on it. My question is when I turn the lens to the 55 and then push the plus and minus buttons at the bottom of my camera to zoom in it appears to be zooming in and then I take the photo and the picture is not zoomed in at all.    I have a new Canon T3i and was able to take and capture zoomed in photos with the lens that came with the camera (EF-S 18-55mm) as well as a Canon zoom lens EF 75-300mm 1:4-5.6. Now when I zoom in with either lens and take a photo, when I review it, it shows original image before zooming. Is it a defect in the camera or inexperience of the operator?    (Two separate questions from separate users but with the same root cause.)

I see a lot of questions comparing full frame (e.g EF for Canon, FX for Nikon) and crop lenses (e.g. EF-S for Canon, DX for Nikon) but I can't find the answer to what would be the differences between the photos taken with say a 50mm f/1.4 EF and EF-S lenses both used with   same APS-C sensor sized camera same ISO same f/1.4 f-stop same focal length same shutter speed   What would be the resulting differences in the photos? Which one would   be brighter than the other due the EF-S lens concentrating the light more? no that's wrong. Both put the same amount of light from the same FoV on the sensor. have greater depth-of-field? neither less problems towards the edges? generally the full frame more lens flare? generally the full frame lens unless there is, or you provide more shading anything else? not really, unless you start down the road of which one is typically of better build quality.   Edit: Added the answers from what seems to be the general consensus from the multiple answers and comments.  Results: My desire to buy a fast medium-high quality lens compatible with both full frame and crop camera's doesn't have to be hampered by the APS-C sensor size of my current camera.  This means I'm willing to part with more money to get a higher performance/quality lens as the performance/quality will be useful now and when I upgrade my camera.  Though reading reviews of some full frame lenses with short focal lengths, look out, as some are really only made to perform well on crop cameras even though they fit on a full frame camera and will give you a full frame picture, the edge quality is very bad.

I'm currently looking for a wide angle lens for my Canon T3i. I would prefer a prime lens. I want to use a wide angle lens primarily for video (so the lens needs a quiet AF motor) but for still photography as well. One thing I don't want in a lens is photos/videos that result in a major fish eye effect. It will have to be an EF mount for my upgrade soon to the 70D. Budget $350  Your input would be appreciated.

You probably know Scott Schuman and his blog (). What kind of lens (that is not expensive) would you recommend for Canon 550D to achieve similar effect (in terms of DoF etc.)? I'm a newbie so I'm not sure how to properly interpret those photos' EXIF info. My guess is, that a similar effect can be achieved using .   PS:   Update: Thank you guys for all the answers, it's much more clear for me right now. I think I'll try the Canon 50mm f/1.4 lens.

My friend has a Nikon 35mm DX lens that I want to use on my FX camera. If I use his lens on my camera in DX mode, does the effective focal length of the lens become 35mm * 1.5 = 52.5mm, or does it just take a crop of the center with an effective focal length of 35mm?

I am planning to buy a new Canon camera body, and am wondering whether to just get the body, or to get the standard 18-55mm lens as well.  I already have such a lens, which I think came with the EOS 600D camera that I bought about 5 years ago, but it might actually be older than that.  (It is marked "CANON ZOOM LENS EF-S 18-55mm 1:3.5-5.6 IS II".) Have these lenses improved significantly over that timescale?
