24-70mm f/2.8
« on: November 29, 2009, 11:11:51 PM »
At present I've got a Sigma 18-50mm f/2.8 that I use as a 'kit lens' and I'm very happy with it. Apart from my 105mm f/2.8 macro lens, this is my fastest lens. I was at a friends dress rehersal for an amateur opera company taking shots for them and wondered whether having the extra reach of the 70mm at f/2.8 would have been beneficial. Is it worth my while getting this other lens? I tend to shoot anything and everything! I only ask as alot of pros seem to have a 24-70mm and a 70-200mm lens. Should I be content with the siggy 18-50mm? It's my birthday soon so I'm thinking combined birthday/Xmas present.......

I've got the 24-70mm F2.8 and it's a cracking lens. In your situation as you have a 18-50mm F2.8 I don't think the extra 20mm would make must difference. I would go for the 70-200mm F2.8 VR as it give you more reach and it's also a cracking lens, the one I use most often.  ;D

Would the 70-200mm f/2.8 be more beneficial than my existing 70-300mm? I know the 70-200 would be better in low light and have greater depth of field but at least I've got the extra 100mm in focal length with the 70-300mm. I think I've got to sit down and think seriously what I want to do with my photography!

Thanks

Maybe, maybe not.  Did you find yourself constantly leaning forward to get more reach?  Were you trying to turn the barrel past the 50mm point?  Do you think your pics needed cropping in post?

I've used the 18-50 Siggy a lot (a LOT - first one wore out....) and it's a very cool lens.

The Sigma 24-70 is frankly, pretty cheap for what it promises.  I haven't read through the reviews but it's possible you'd be trading one of Sigma's little gems for one of their more standard offerings.  You're also more likely to find yourself backing into a wall because it's "only" 24mm than rejoicing at the extra reach.

My 24-70 is by far my most used lens but (1) that's the Nikon which was very possibly made by pixies on a good day (2) I'm on full frame so the reach is almost identical to your 18-50 on a 1.5 crop.  If I were you I'd look at a longer lens - maybe a 70 -200 or something similar.

Does it have to be either/or - why not follow Old Boys lead and use AND.  More glass = more options and you only use the extreems of each lens when it's the only option.

ahh lenses....OOH How I wish for £1200 to magic it's way into my bank account so I could buy the SONY 70-400 f4-5.6, (which btw just pipped the Nikon 80-400 by 2% in the Amateur Photographer comparison 3 weeks ago) In all seriousness it is a cracking looking lens, I just wish that Jessops would let me hire one for a weekend to take to Richmond Park, think of the deer shots I could get with that baby.....A stupid question though I know the convertors increase the focal length of the attached lens by whatever e.g. 1.5 or 2x...but is there any difference in a SONY/CANON/NIKON branded convertor or buying say KENKO (camerworld SONY Brand £289.99 or Kenko for £174.99 big difference) not that I really have any money at all at the mo just planning for the future. And am I right in thinking that if you had say a 2 x convertor and attached a 70-200 you actually get the 35mm equivalent of 150 - 450 (or thereabouts 70-200 x 1.5 for the crop factor = 105 - 300 x 1.5 again for the teleconvertor = 157 - 450) and is there any loss of image quality using these? forgive my ignorance but I just get confused with the crop factors of sensors etc = focal lengths of 35mm equivalents...I'm off for a lie down now before my eyes explode and my brain bulges out of my ears.... ??? :-[

The Kenko is regarded as quite good but not as good as the makers own brand. The Nikon is 80-400mm lens and is a cracking lens if the subject doesn't move, but any movement can spoil the shot. Jacobs do lens hire but may be mainly Canon and Nikon.  :(

Any converter will magnify the image so, on my 400mm F2.8 a 1.4 will give me the same reach as a 560mm lens or with the 2x converter, will give me 800mm. The crop sensor on the other hand doesn't increase the range but gives you the same field of view, so you see the same image as the longer lens but wont bring the subject closer.  ;D

Keith I have used a Kenko x2 converter with my Nikon 70-200 and it does seem to work ok, not a lot of difference to be honest, won't  use it that often so I really didn't want to pay out for the nikon version.
One thing I would say is though that you do need either prime  or good quality lenses, it doesn't work at all well with the 18-200 Vr that Dave uses .

Just a quick example taken during the fallow rut
