Lens dilema

Discussion in 'Lens Lust' started by icecavern, Jun 20, 2007.

  1. Right I have a bit of a dilema so hopeing the Cafe can offer some advice...

    At the moment I have the kit in my sig but I'm after a bit more reach at the long end. Basically at times I need a longer lens when I'm shooting wildlife, mainly birds. I'm also thinking more speed focusing would be nice for when I'm shooting touring car racing.

    So what I was considering, is selling the 80-200 and 300 lenses and buying myself a 70-200 AFS and then some TC's to increase the focal length. I figure with a 2x TC I'll have a 140-400 5.6 lens and the 1.5 tc would give me a 100-300 f4 so I should get slightly more reach but retain the current focal lengths.

    Is this a mad idea? Is there a better way? Funds aren't unlimited which is why I'm not considering a 400 f4 :frown:

    I have seen a Sigma 300 HSM f2.8 at a decent price and considering that as an option too.

    Comments and suggestions greatfully recieved.

    Hi Pete,

    I have used the nikkor 70-200/2.8 vr. an excellent lens with my tc 1.4.Af is fast as expected.however, my action shots are limited to chess or bridge.

    other proponents of this excellent lens could offer you better advice.

    Good luck.
  3. Thanks for the comments.

    I have to say I'm tempted sell the 300/4 I have and go for the Sigma 300/2.8 and then get a TC for it.

  4. The 70-200 VR will work well with the TC14 and TC17, but not with the TC20 (it works but the image degredation is unacceptable). I would recomment "long lens technique" when using the TC17 and if you have it, MLU, from a tripod, because you will never get sweet light AND 1/500 shutter speed.
  5. I guess with the TC17 I only get a 340mm at over f4, so not a great step up from what I have now I suppose :( 
  6. I don't know how far away you're when you're shooting birds or racing cars. To me, 200 + TC is not long enough. I actually had quite good results with 300/4 + TC 17 so don't discard that option. You will always need more mm.

    So 300/2.8 + TC is a good choice. Or if you're doing it frequent enough, get a 500mm.
  7. Pete, I have

    gone the route of a 70-200 with a 2x Kenko Pro 300. While not a "perfect" solution, it does get some long focal lengths for not much beyond the 70-200 cost. All the functions of the 70-200VR operate with the 2x Kenko Pro 300.

    I tried a friend's 50-500mm Sigma (Bigma) and would estimate that both the magnification of the 70-200 with 2x as well as the focus speed are nearly indistinguishable form the Bigma.

    I have not had the converter long enough (only 5 days so far) to do a lot of comparison, but will try to post a some images in the next day or two. In the mean time, here is one from the 70-200 and 2x with very minor cropping:

  8. Unfortunatley funds wont allow a 500mm :( 

    I find with birds I need a bit more than 300mm at times, so I'm thinking a 300mm+TC would give me the flexibility especially if I got both a 1.5x and 2.0x convertor for the sigma.

    I think the main thing I'll miss is the light weight of the 300/4
  9. Pete, have you considered the Sigma 120-300/2.8?
  10. Hi Panos

    I hadn't until I started searching for reviews on the 300/2.8 sounds like the 120-300/2.8 would be a good choice as well.

    Unfortunately for either I would be buying used and they don't come up that often so will keep my eye out.
  11. Will do, too :smile:
  12. Hi Pete...
    We have both nikons, the 300f4 and the 500mm. We shoot birds, wildlife, whatever moves, and often doesn't move...

    We use nikon tc's after selling the Kenko tc's and really like the quality difference.

    Both lenses are good for what you are shooting. But doesn't make sense to me why sell the great Nikon 300 f4 for a Sigma, even at f2.8. (I have never used this Sigma lens and am not speaking bad of the lens, but the Nikon is such a good lens.) Go to the Nikon 300 f4 fan club here on this forum.

    We found the 500mm at KEH, used, and it is a wonderful lens.
    And Firelarz has a 500 for sale here on this forum:

    Maybe saving up a bit you might find you are much happier.
    However........you might even begin to lust for a 600mm lens after you have the 500, so beware!!! You have now been warned! :) 

    We really do enjoy the length we get with the 500...
    Hope this has helped some,

    Don't discard the Sigma 500mm f/4.5, optically a great lens and at half the cost of a 2nd hand Nikon 500mm f/5.
  14. Unfortunately a 500mm is way out of my budget :(

    What's your budget? The Sigma 500 can be had for a grand.
  16. Only looking to spend £750-800 max
  17. I can get a used but mint 70-200VR from a trusted source for £900 but it sounds like it wont quite help that much as the 2x doesn't sound like a great match for it, but then Joe seems to get on OK with a 2x TC on it :confused:

    At £900 I'd stump up the extra for the Sigma 500 TBH, it will blow away the 70-200 with a TC 2x on. Theres not much else in your budget that would match that Sigma.
  19. Yes but if I get the 70-200 I'll be selling the 80-200 to help fund the purchase.
  20. Well I pulled the trigger, bought a Sigma 300/2.8 hopefully be here tomorrow :)
