APS-C to Full-Frame Lens Focal Length Crib Chart — Mainly For Sony E-mount Lenses.

by Anura Guruge


Well as I elaborated yesterday,
I have to get my head around this focal-length
‘equivalence’.

Since I am used to thinking in APS-C terms
I needed my own crib sheet just to be on the safe side.

As you can see I am focusing on Sony E-mount
focal lengths.


Click to ENLARGE. Yes, I have an Excel spreadsheet. I can plugin whatever numbers you need THOUGH it is but a trivial exercise in multiplying by 1.5 or dividing by 1.5.


Here is a picture from yesterday IF it helps.

To get the same Depth of Field (DoF) that I got with a 40.7mm APS-C lens,
I would need a 61mm Full-Frame lens.


I needed this to work out what lenses I need to consider.

With FF, anything below 27mm will be WAY TOO WIDE for I!

I am probably better off sticking to FF 50mm and more. {SMILE}

Getting My Head Around The LARGER ‘Field of View’ (FOV) Of A Full-Frame Camera.

by Anura Guruge


This, for I, is going to get some getting used to.

The irony being that I like tight, close-up shots.
So, my preference for zoom lenses and zooming.

With the Full-Frame Sony a7II 
I will have to stick to ‘zoom’ lenses.

Let me EXPLAIN.


A view of Acadia with a APS-C sensor and a lens at 40.7mm.

I will need a lens capable of giving me 61mm to get that same view.
IF I used the same 40.7mm there will be MUCH MORE scenery in the picture.

That could be good or bad and will affect the composition.

The irony is I like TIGHT compositions.


It gets even CRAZIER when you use a 1/2.3″ camera
such as my beloved Nikon P900.

That is another Acadia view, this time with the Nikon P900,
using 35.7mm focal length.

To get that view I would have to use a lens capable of 200mm
on the Sony a7II.

The Nikon P900 picture is below.


The Nikon P900 picture used above.

You can see that this is quite a nice view.

Yes, I will be able to get this same exact view with my Sony a7II BUT I will need a 200mm lens.

And, yes, I will get a zoom capable of 200mm. {SMILE}


IF you are not really into photography you are going to be wondering what the heck I am talking about.

This has NOTHING to do with resolution, i.e., 12MP, 16MP, 24MP etc.

The Sony a6000 that I just traded in and the Sony a7II have the SAME EXACT resolution; 6000 x 4000 pixels, 24MP.

But, the Full-Frame Sony a7II has a much BIGGER sensor and when it comes to cameras SIZE has always mattered.

A bigger sensor the more light you can get — all other things being equal BECAUSE there is more surface area to capture the light. That is usually the MAIN reason to go with Full-Frame. That is why I am finally going with FF. If you, of course, like shooting wide vistas then FF is a boon.

My problem is that I like tight, cropped shots! So, I really should be NOT getting a FF.

But, all is not lost. It just means that I have to stay at the higher zoom range when it comes to the lenses I use on the a7II. Later today I am going to create a Excel Spreadsheet to help me out.

So to get a 50mm APS-C equivalent shot, I would need a 75mm lens on the a7II.

It just means that I need to be careful not to get anything much below 30 – 35mm FF.

I will sort it out. Just need to get my head around it.

Yes, I can also use APS-C lenses on the Sony a7II but that CROPS the image and that is a whole different issue!

Not sure whether Netanyahu would be been invited
to Arlington National Cemetery for Veterans Day.

But he is NOT taking any chances. He will NOT be in the U.S.
Leaving Tuesday night. Interesting.

Click to ENLARGE and read here. From haaretz.com/israel-news/. Netanyahu is leaving after he speaks at the U.N. on Tuesday.


Israel, as I had found out from my friend, Itzik,
does NOT mark November 11 as Veterans Day or Remembrance Day.

Kind of makes sense when I think about it.
It did NOT exist during WW I or WW II.
So on that score it makes sense.
But I would have thought they would join the
WW II allies who in one form or other mark November 11.

Obviously INDIVIDUAL Israelis can and DO
honor November 11, Veterans Day.

This is the Israeli equivalent of Veterans Day/Memorial Day.
