I'm pretty sure I know what the answer is but I wanted to check

I want to get some more lenses for my Af100.

I have the 14-140 lumix. Which I'm really happy with (especially after hearing some negatives about it) But I have to say it is a little on the slow side, even sometimes when I'm outdoors I feel I need an extra stop.

I've been wanting a Voigtlander 25mm for ages, I have heard nothing but good things. But it's a 25mm which if I've got my figures straight would mean it's a 50mm on the AF100, correct?

50mm sounds great to me, almost the same as a human eye so in theory would be a nice field of view. But when I zoom my 14-140mm to 50mm the field of view seems really small. Especially for indoors in average size rooms. Would this be true or are my figures way off (I was always crap at Math).

Thanks in advance

A 25 mm optic will stay a 25 mm optic and what you see with your zoom is what you will see with the Voigtlaender. The befuddlement comes from different sensor/filmgate sizes that give you a different FOV.

http://www.abelcine.com/fov/

As your zoom projects the image to the same sensor (size) as the Voigt would - no difference here because no change in sensor/gate size happens.

And about the 50 mm being "normal" - first "normal" is a question of definition and cultural convention as our eyes are really constructed slightly differently. And only our "image building software" within the brain tends to finding what a 50 mm optic projects onto a 35 mm still frame gate (as with Canon 5D) as being nearly what we may feel is "normal" (a lot of still photographers find a 40 mm to be more "normal" than a 50).

For a 35 mm cine gate size sensor "normal" would be a 30 to 40 mm. So 25 mm on the slightly smaller gate/sensor sized MFT is .... quite normalish .... ;-) Apart from that the Voigtlaender rocks. Only downside: It's prize.
 
The amount of times we all post the Abelcine FOV link... maybe it should be a 'super-sticky' so everyone knows about it :cheesy:

There's so much confusion on this all the time...
 
Yeah I have the 20mm pancake and even that won't capture everything your eye sees in a small room. If you really want something that wide- consider heading closer to 10mm. Still the 25mm voigtlander does rock- as one tool in your arsenal. There's no one size fits all lens, though if I had to pick one thus far it'd be that 20mm.

" The 25mm Voigtlander will have the same FOV as the 14-140 set at 25mm. "

Of course, I told you I was rubbish at maths.

Thanks for all the replies and links. I do understand the crop factor and I do understadn that zooming isn't the same due to perspective changes. It was the whole trying to figure out what to set my native lens to to get a rough idea that confused me.


Thanks again

In his iconic painting The Scream (above), Edvard Munch used a 50mm paintbrush, on a fullframe canvas.
But then when he used the 50mm brush on a 4x3 canvas (below), he got the, well... you know... :happy:

I was curious about this thread so I clicked in and then BAMN I get contaminated by the 2X curse!! Thanks everyone :undecided

Blame groveChuck - he mentioned the dreaded words... :shocked:

We're all cursed now... it's just like Beetlejuice... say it 3 times... and something happens...

But I'm not scared... 2X... 2X... 2...
 
Ha ha wow, lot of people with some time on their hands :)


I bought the 25mm and all I can say is wow, it's awesome!

Everything about it is great. The FOV, the colour and the quality of the build.



Thanks everyone for your great advice. You can carry on with your crop factors now.
