Nikon SLR camera lens questions?




Kasey


Hi!
So for my photography class we had to have an SLR camera because we learn how to develop film and all that, so I ordered a Nikon n2000 from Etsy but it only had the body and I had to buy a lens which when I went to my local camera store they only had one lens that would fit it and its a "zoom" lens I guess and I can't really take picture up close or anything which I really need to do. So I found a lens on Ebay for pretty cheap; a Nikon Nikkor 50mm F/1.8 Lens, will this work for my camera? I really don't know what I'm doing when it comes to these things so any additional information would also be helpful. Also if you know anyone selling a lens that would work that isn't too expensive please let me know!

Thanks a million (:
Okay so it says Nikon Nikkor 50 mm F/1.8 D AF Lens. Does the D and the AF make a difference?



Answer
The 50mm f1.8 Series E, or 50mm f1.8 AI/AIS will do the same job as this one a lot cheaper.

Your camera will take ANY lens, Nikon or third-party, in Nikon AI or AIS mount - they're a little more expensive than contemporary lenses from other manufacturers, because they fit modern Nikon DSLRs, but the used market is full of them.

One to look out for is a Soviet made 300mm f2.8 - it's a bit specialised, but was made for the Kiev 17/19/20 series of 35mm SLRs and costs about a quarter the price of anything comparable.

Seriously, I'd suggest a 28mm f2.8 and a 135mm f2.8 to add to the 50mm, these will give you a decent starting kit, and a set of extension tubes are a cheap way to get into close up photography.

Nikon Camera lens help?

I want to buy a fisheye lens for my Nikon D5000 and dont want to spend too much money but I want a nice fisheye with not too much vignetting. All i could really find in 52 mm was http://opteka.com/optscfe.aspx. I was wondering if there were any alternatives or if i should go with this.


Answer
The link in your post doesn't work, so I'm not sure if we're talking about the same lens, but I recently bought the Opteka 0.20x fisheye lens. Forgive me, but I am going to be lazy and just copy and paste the review I wrote on it (posted on Amazon.com if you want to see the pictures I mention). It should hopefully answer your question on vignetting.

The Opteka fisheye adaptor is not a stand-alone lens that attaches directly to your camera; it is a converter lens that must be screwed onto the front of an existing lens.

Although the product page states this is for certain Canon cameras, the box only says it is "custom threaded for your camera" without mentioning any brands or models. The brand/model of your camera is unimportant. What is important is to note the diameter of your lens and to ensure that the front of your lens has a screw thread. The fisheye itself is 52mm in diameter and comes with 52-55 and 52-58 adaptors. This means that the fisheye can attach directly to a lens with a 52mm diameter while the adaptors allow you to attach the fisheye to lenses with 55mm or 58mm diameters. Note: I know that stores sell adaptors of other sizes (called step-up or step-down rings) but having never used them myself, I can't tell you if they would work with this fisheye.

I tested the lens outside in sunny conditions. I used a camera with a 1.6x crop factor (a Canon 400D). The center of the image seems decently sharp; the edges are expectedly blurry. On my 24mm lens, I can see the lens barrel at two sides of the photo. My 50mm lens does not show the lens barrel in the photo. Please see the two photos I uploaded to the product page for more information.

A short lesson on crop factor: If you use a 50mm lens with this 0.20x fisheye, you are converting the lens to a 10mm (50mm*0.20). However, if you aren't using a full frame camera, you must multiply by your camera's crop factor to calculate the focal length that the fisheye is converting your lens to. In this case, the 50mm lens is converted into a 16mm (10mm*1.6).

Bottom line: This converter is a cheap alternative to a real (and very expensive) fisheye. Unless you have money burning a hole in your pocket or are a professional photographer, this is most likely the lens for you.
