67: 100mm macro f4 vs 105mm f2.4 & 165mm f2.8 vs 200mm f4

Hi all :-)

Does anyone prefer the 100mm over 105 as a normal lenses? If so, why? And do you miss the 2.8?

And for portraits - for those using the 200mm for this, are you missing the 2.8? I'd say I prefer the longer focal length, but I dont mind the 2.8 either :-)

Cheers
Peter

I prefer the 55-100 zoom @100mm over the 105 for landscape work due to its f/32 stop. The 100 macro also has f/32 so it would be OK too. Lens speed is not a consideration for my work.

I only use the 100/4 for macro work and mostly with the LSC, so the 105/2.4 is used for regular shooting along with the 90/2.8 & 75/2.8.

For portrait work the 200/4 is nice for head shots and the slower speed is not really an issue. You get enough isolation in a studio, due to the close focusing capabilities. (late version)

My 2cents: i use the 135mm f/4 for macro; actually my very first 6x7 lens and 30+years old(?). Occasionally I add a helicoid extension ring for more! My 90mm, in leaf shutter or plain, are my norms. I use a few different choices for portraits including the 165mm LS lens - task specific. I rarely used my 200mm and sold it. I frequently opt for 6x6cm format for portraits, tho. I think your questions are good and need a priority assigned to each task. 75mm is a wide angle; 90mm-135mm is normal range; 150mm longer are telephoto range. What suits you today? Btw: I am not usually concerned with wide/fast aperture-low light not a usual concern. I use a suitable tripod frequently.

Thanks for getting back to me folks :-) It seems like the 200mm is a good option for me. And it also seems to me that the choice I have to make for normals isnt between the 105 and the 100, but the 105 and 90 ;-)

I have the 90LS and 105/2.4. 90 is lighter and of course the LS, 105 has that unique look.
As for portrait lenses, I have the 165/2.8 and 300/4. 165 and 200 aren't that far away when it comes to focal length, so the 300's another option, and it's f/4 like the 200 but longer, so that's that.

The 67 200/4 is an optical update over the 6x7 200/4 generation. A good lens but a bulky design. The front element is recessed so far that you practically have a built in lens hood until you put on a filter. The 165/2.8 is much more compact and a lens I'd rather carry around.

All four lenses are really good. The 100 mm f/4 Macro is specialized for close-ups but requires very short distances between the subject and the camera and that can lead to awkward situations. My new latest version of the 105 mm f/2.4 is incredibly sharp and better suited for use at infinity. The 165 and 200 are also very sharp and easy to use with great success. The 67 200 mm f/4 was my first lens along with a 67 55 mm f/4 when I started shooting 120 film in 1991 and has always proved to be magnificent. I got a used 67 165 mm f/2.8 much later (in like-new condition) and I like it very much on my 645Z with the Pentax adapter. It is light and affords a brilliant viewing image. Decisions, decisions ... You almost can't go wrong with any modern Pentax 67 lenses.
