The book is excellent.

Tell us how it is on FT format, just few extracts


... at wide open aperture of f/4, the sunflower is isolated - in effect, it's all alone - but at f/16, due to increase in the dpeth of field, it has quite a lot of (background) company.

Looking at that picture clearly f/16 is not where the mFT aperture would be, and neither would it sufficiently isolate the sunflower at f/4 on mFT (f/8 FF equivalent).


Clearly a picture of crashing surf taken at f/4 and 1/500 sec would capture action stopping detail of the surf as it hits the rocks; a correct exposure using f/22 at 1/15 sec would capture less action stopping detail and show the surf as a far more fluid and wispy, somewhat angelic element.

Again, if this was f/22 on mFT, what would it be like with FF format? Do you even use f/22?

story-telling composition... focusing all objects from near to far... relies on maximum depth of field, you would first choose to set your aperture to f/22 and then align distance above your distane-setting mark on the lens.

Story telling at f/22 with mFT? - Wonder what else one could learn from it.

These are only random extracts, and if you truly are just learning, it will confuse jesus out of you. Even if you already do know and understand what the crop factor is, try the same shutter speed for the same framing (with different focal lengths), see how this works out for you.

No-one is saying it is not a good book, or it is not worth having, but you really have to think and understand what the settings mean, and the settings with examples is pretty much how the book goes by.

So if you do have it, what do you learn for it? Please share.

Converting f-numbers between FF and MFT is something anyone can do on the fly in their head. It really is that trivial.

You're being too kind. It would appear that at least one of the primary participants in this thread is too intellectually challenged to manage simple division by two on the fly. For anyone with average intelligence or above, you're right - it shouldn't be a problem.
