What Lens is mostly attached to your Camera and why....

I suppose mine is the 300f4 as I shoot a lot of wildlife

Got to be the canon 24-70 F2.8, It's the perfect all rounder.

18-55mm at the moment, its my only lens  at the smaller end

When you fellas are quoting lens focal lengths, are they 135 format equivalents, or the actual true focal lengths? The reason I ask is that there may be a scaling factor applied due to the sensor size on some cameras (probably not yours).  My Fuji S9500 has a permanently mounted lens and sports a 6.2 mm to 66.7 mm zoom. The scale factor is about 4.5 so I get an 135 format equiv range of 28-300 mm.

  Any idea what the form factor (actual physical dimensions) of your sensor is?  This would shed some light (no pun intended) on the "bigger is better" MP debate.  More MP density is not better in the long run as the sensor tends to get noisier as it gets more micro-miniaturized. So what I'm looking for is an optimally large enough sensor in MP to achieve high resolution yet  also not be so small physically that it becomes overly noisy.  There's a bit of a debate on the net about all of this.

Thoughts on this?

I'm with Phil on this one!

Oh to be able to afford that Sigma 200-500 

Any chance we are doing a secret santa this Christmas?

The slr lenses are all quoted in 35mm terms. The different sensor sizes give a conversion factor which is then applied to the focal length. For Canon 300/350/400/450 its 1.6x so a 50mm lens becomes an 80mm etc. Smaller Nikons are 1.5x and the four thirds system is 2x. Exception being the full frame sensor cameras from the manufacturers where what you see is what you get. This is why the 'cropped sensor' works better with telephoto lenses - it effectively increases the focal length. True that cramming more pixels onto the same size sensor isn't always best. It seems to require more and more sophisticated software to get rid of the noise generated.

Ah!  This tells me intuitively that my Fuji, using a 4.5x scaling, and a 9.5 MP density is already much more miniaturized than the Canon SLRs. This is a trend in offering newer cheaper high-density MP cams. It also explains why I get so much more noise than a canon , especially in low light.

Thanks James - you've convinced me to upgrade (as soon as I sell some prints -hint,hint) ;-)

Hmmm..has to be either my Canon 100-400L or the Sigma 150-500mm, but my 50mm 1.8ll is always in the bag in case of the need to get much closer turns up

Thanks Bev for bring this thread back to life.

I think I need to update mine to the EF 500 f4 IS. Seems to be on most of the time plus a 1.4x Extender...  Always have the EF300 f4 IS, EF70-200 f4 IS and EF100 f2.8 macro with me as well..

My wife Joan is with me most times and uses my 30D with the EF100-400 IS attached.

Lately it's been a Sigma 50mm macro for indoor stuff. My favourite however is the 70-200 f4L. Light, compact and without doubt one of the sharpest lenses I've ever used. The ivory finish does attract attention but everything else about it is flawless .

[phil1066]

You guys are using words, but I dont understand what you are saying 

Only kidding, some serious lenses there 

[NIGDAW]

Hi, I would have to say that the wrong lens is on my camera most of the time. If I'm taking landscapes with my 10-20 Sigma there will be a kestrel hovering above my head or a herd of deer standing behind me.

Thats a great lens and one i would of chosen had it been that i didnt want to take another mortgage out ! although not near the L series quality i settled for the Sigma 150-500mm, gives that extra reach without having to use TC's  plus its handholdable.

Its nice when partners share the same hobby, my husband is an avid fisherman although he likes to come out now and again when he uses my old 20D with any of the lenses that are'nt being used at that time.
