Has anyone used this method? I have seen this mentioned in several blog sites. The explanation online is somewhat illustrative. Wondering if anyone can share their personal experience and process for creating images using this method.

Christian, thanks very much...

I have the D500. Using a Sigma 150-600 with a 1.4x converter will yield what effective range? Is the lens and converter math 600 x 1.4 = 840mm and then the crop factor of 1.5 = 840mm x 1.5 = 1260MM? Is that the math? Thanks to all the math majors in the group (and those who know about crop sensors.)

Thanks. Any reason to use a zoom or can just move around for focal lengths?

I am doing a series of headshots for friend. Which of these lenses would you recommend that I use? Will be outside so light is not an obstacle requiring a faster lens. Using a Nikon D750. Thanks

I recently purchased a Nikon D600. I think it is rated to have 150,000 shutter activations. Does this mean that it must be refurbished when that number is reached. Is there any impact on the actual shutter speed accuracy when the shutter count exceeds that number? Thanks for your input.
