105mm vs 200mm working distance

<p>Hi,<br>

can someone be kind enough to post working distances for Nikkor 105mm and Nikkor 200mm macro lenses for various enlargment ratios?<br>

I am very interested in working distances for 1:1, 1:2, 1:3 and 1:4 ratios since I intend not to take photographs only of small bugs but also of snakes and shy reptiles.<br>

Can be also MFD's for those ratios instead of working distance, I can do the calculations later.<br>

Thank you in advance.</p>

<p>I have my 105/4 here: 1:1=0.42mts (with PN-11), 1:2=0.47mts., 1:3=near 0.55mts., 1:4=near 0.66mts. I can read this distances on the lens barrel.<br>

The 105VR has shorter working distances: 1:1=0.31mts., 1:2=0.4mts., 1:3=0.5mts., 1:4=0.6mts.</p>

<p>Thanks Jose!<br>

It seems magnification decreases fairly quickly on 105mm macro lenses.<br /> <br /> These are minimal focus distances right? Not from the end of lens (working distance) but from sensor/film (focus distance)?</p>

<p>Right. A 105/4 without hood is 15cms. at 1:2 (a bit more than 20cms. with the PN-11 if 1:1), the 105VR is less than 12cms at any magnification. Add 4.65cms. for the flange focal lenght and you will know the overall lenght from the lens "nose" to the sensor/film plane.</p>

<p>Because some (most?) macro lenses decrease in focal length as you focus closer, the difference in working distances aren't always what you'd expect when comparing lenses. The older 105mm/f4 seems to maintain its focal length as it is focused closer.</p>

<p>Here is a link with a chart of working distances for different lenses:</p>

<p>Thanks Alan! Nice charts, that is what I was looking for.</p>
