Also, if you are considering perspective, then you need to get all the lenses with you as you cannot get a perspective with other lens.

All these lenses will exhibit the same perspective IF used from the identical camera location and subject distance.

So are you saying if the subject is let’s say 2m away from the camera with a 21mm lens or with a 135mm lens, you’ll get the same perspective? Or am I wrong what you mean? Because I bet you get different perspectives as wide angle extend the fore/back ground and tele lens shortens it.

 

But maybe there is a confusion with wording

No, you have it wrong. A lens does nothing with perspective except record it.

The perspective in an image is solely dependent on the subject distance. Jeff is spot-on. It is a common misconception that longer focal lengths flatten the perspective. People forget that they have to move further out to get the same field of view. If you take a photograph from the same spot the perspective of a 21 mm lens cropped to the FOV of a 135 mm lens will be exactly the same as the same image taken with the 135 mm lens

Using a longer focal length is more akin to cropping an image.

The perspective or relationship between a foreground object and a background object does not change if the camera location and subject distance remain the same.

The perspective or relationship between a foreground object and a background object changes when the camera location is changed to keep the foreground object the same size in the camera frame.

As you can see from the above examples the perspective remains unchainged if you keep your camera position unchanged and if you only change lenses because you want to change focal lengths (lets assume you change from 28mm to 75mm). I just want to add the following: Changing lenses without changing your position means changing the angle of view and this will result in the exact same as if you had shot at 28mm and then in Lightroom you would have cropped. What you do is simply changing the angle of view as mentioned before. I evidently do not speak about the data you loose when cropping. If though that loss in data would not matter to you at all because you shoot photographs that are viewed on a smart phone screen only, then actually you would need nothing else than 1 single lens, a wide angle of course, and the preferred angle of view you simply set in Lightroom later. You can then easily simulate a135mm lens when a picture that was taken with a 21mm is cropped enough. You can save a lot of money that way at the expense of image detail or image quality.

 

You could even go a step further and say that the term „focal length“ is not a clever measure for lenses. Imagine a 50mm lens on an M10 or a 50mm on an Olympus with its smaller „four third“ sensor. This results in a different angle of view and as a matter of fact in a different picture (with the same perspective). If we want the same angle of view on the cameras with the different sensors we would have to take a 25mm lens on the Olymus whereas we need our 50mm on the Leica full frame camera. The „angle of view“ would be the better term to define a lens as we would have one clear term for any sensor size. And as the next consequence the f Stop will have to be questioned. The f-stop is as confusing as the focal length and there would be a much better term here too. But this is another story.

The 135 for the puffins at the rocks at the west of Scotland

The 28 for the landscapes

The 50 for people, culture and also landscape with panorama stitching

This is because you want to take only 3. I would use the 135 then for portraits which I would otherwise have done with the 85

I always think there's little you can't do, especially for travel, with just a 50 and a 28.

leave the rest at home.. I think the point of the M is the compactness, isnt it?  I will travel and take only 50mm.. but knowing you want to do landscapes throw the 28mm in there.

Zeiss Distagon 1.4/35 ZM 

Zeiss Planar 2/50 ZM T*

Zeiss 28/f2.8 Biogon ZM T*

Zeiss 2.8/21 Biogon ZM T*

Zeiss 4/85 ZM Tele-Tessar T*

Leica Tele-Elmar-M 135mm F4

 

Which 3 lenses would you take?

 

 

 

I think the answer depends upon how you  are travelling. If you are driving around but based in only a few hotels you may as well take the lot (they will all easily fit into a Domke or Billinghma bag) and then take out for the day what lens(es) you are likely to want. If you really only want to take three then 28, 35 and 85 seems like the obvious choice to me but that is just because that is my preference. The last time I did a multi-week touring type holiday was before my daughter was born and when I used an M8 with 28 and 50 (effectively 37mm and 65mm). I don't remember hankering after any other lenses though if I did it again I'd probably take my 28, 35 and 90 lenses.
