I am comparing the cheapest way to cover a set of focal lengths on DX vs. FX. That is my original statement in my original posts which you called a myth.

First of all, the cheapest way to cover a set of focal lengths has been shown to you by chlamchowder, FX is cheaper, by a significant margin.

Funny that chlamchowder said exactly the opposite if one restricts oneself to new lenses:

With new lenses, FX and DX trade blows. For someone like the OP who probably just wants to get to certain focal lengths without too much concern about DOF or low light capability, DX provides a cost advantage.

As my list clearly showed, and as I spelled it out in another post, my statement was based on new lenses. Now, you don't acknowledge that I spelled that out, nor that there is a significant difference between including used out-of-production lenses or only new lenses, or that in fact for new lenses my statement is true.

There is a very simple rule when discussing a matter: you have to acknowledge you opponent's position before you criticise it.

What he said is if one wants to get to certain focal lengths, but no concern about DOF or low light capability. then DX is cheaper.

Which is 100% what I said and you called a myth.

it does not resemble what you said which is

"to cover any set of focal lengths, you will have almost universally pay more for a FX set than a DX set"

There is no qualification that it must be new, and there is no qualification that you compare the same FL but ignore everything else.

What is the difference between "if one wants to get to certain focal lengths" and "to cover any set of focal lengths"? Both say that going to a specific focal length (or focal lengths, we both used the plural) is essentially the only criteria when choosing the lenses. And both statements say that for multiple focal lengths (ie, not just one single focal length) DX is cheaper which is the same as saying that FX is more expensive.

And yes, I did not spell out that I only considered new lenses but then I had replied to subthread that only talked for three straight post only about new lenses (Grevture, paulski66, Grevture, me). And after you called by statement a myth, I directly asked you for examples which would show that my statement was not true. But you refused to do so without me first answering a question about two specific cameras. Ok, so I answered the question, correctly as you confirmed. But you still did not produce any examples. And then two post later I showed you a list which clearly showed that I only considered new lenses. You could have ended that much earlier. I provided more than 30 lenses as examples and you never even presented a single example.

Lastly, and amusingly, you place such a peculiar boundary conditions ("cheapest") and then you turn around and say :

How is 'cheapest' a peculiar boundary condition when talking about which lenses are cheaper?

Because no one goes for the cheapest for every thing.

Nobody buys the cheapest lens for a given focal length (or a set of focal lengths)? Isn't it rather the other way around that the cheapest model is usually the one which sells the most?

When people ask "what is cheaper" there is always a implied condition that any candidate is of a particular quality or performance standard.

As for example only looking at lenses with the same brand as the camera or only at relatively modern lenses which implies having modern features like VR and AF-S.

And 'cheaper' is still a much more general condition than comparing just two individual camera models that are years apart.


I introduced the word 'peculiar' into the discussion when you appeared to answer questions about two sensor sizes (and associated lenses) by comparing two individual camera models from different generations.
