I still use his site for compatibility charts or variations between each version of a lens though. So for facts and figures he's OK, but his opinions on things are greatly exaggerated or plain untrue.Tog and nifty..... Grrrrrrr

Doesn't the v stand for "variable"? That's what I was taught anyway :shrug:Aperture Value and Time Value? Seems quite sensible to me![]()
Therefore it's not extra reach, it's reach you lose if you move to full frame. .
a full frame user it does all make sense, but as an APS-C user learning it confused the hell out of me everytime some reviewer spoke of extra reach for aps-c users.
Rant over....
artyman said:I daresay Medium format guys would say that a FF is a cropped view. It all depends on focal length relative to frame or sensor size. If I recall 2 1/4 square the standard focal length was around 85mm, using an 85 mm on a FF would give you a cropped image.![]()
For starters; 'full frame'. But I also hate 'full frame' users talking about the APS-C 'multiplication factor'. I would hazard a guess that the vast majority of DSLR owners never owned a film SLR. I'd also hazard a guess that 99% of these people had/have a 'crop sensor' camera before upgrading to 'full frame'. Surely the point of reference for a 300mm shot is their *first* 300mm shot, likely taken with that 'crop sensor' camera. Therefore it's not extra reach, it's reach you lose if you move to full frame.
Now a full frame user it does all make sense, but as an APS-C user learning it confused the hell out of me everytime some reviewer spoke of extra reach for aps-c users.

Conversely, moving from 35mm to a crop sensor was a bit odd! I'd been using 35mm for many years and could see what lens I needed for a particular AoV. With the arrival of a crop body in the bag, I was having to divide the normal FL by 1.5 to know what I needed on the crop body. It got even more confusing when I was out and about with 35mm and crop bodies in the same bag (I missed my wide angles, having got used to 12mm on 35mm!). All restored to normal - FF body in the bag and the crop is on long term loan to a friend who might buy it from me.
.....The way the general mood of this forum and FF as 'standard' is very narrow minded...
Well said Phil... I'm getting bored of reading threads, especially those relating to prospective lens purchases, that insist on the need to future-proof against the possibility of moving to full-frame..... it's as if you buy a DX lens and you might as well throw it in the bin, as it'll devalue to zero because no-one wants to use crop anymore.

I have never owned a full frame DSLR before but I always convert to the full equivalent when looking at a lens dunno why it just makes sense to me that way
Odd that, because I'd used 35mm for years too, but I'd also used MF. So understanding that focal lengths were different without having to resort to calculations was a simple task - then as now:shrug:.
I've not used MF enough to get used to the AoV available from any given FL and now only use an Fx body. I did spend a while using Dx for most things and 35mm for most wide angles (especially 12 mm up to 18 (where the 35mm equivalence due to the 1.5x crop factor met the shorter lengths (in AoV terms) of the 12mm when fitted to the crop body). It was the swapping between the bodies that caused brief confusion.
But that doesn't help users of (only) crop cameras, who don't need to know what their lenses 'equate to' in FF terms. It's totally nonsense, they only need to know that their 18-55 is a standard zoom, a 35mm (ish) is a good standard focal length, a 50mm is a short tele, 85-100 is a medium tele and anything longer is a long tele, 10mm is Ultra wide 18mm is wide etc. Why would it matter to a crop shooter what any of that means on FF:bonk: There are many important areas of photography they need to know about, without someone needlessly banging on about what changes if they go FF (which they'll then fell the need to do, to become 'normal'):shake:
To a pure crop shooter who has never used FF/35mm/MF etc, there is no need to use any conversion - with some experience, they will (or should) be able to visualise the FL required. If/when they move up to FF, they'll want/need to be able to convert that experience to decide which lens to use on their new body until that becomes 2nd nature. Not banging on about it, merely pointing out a fact!
The way the general mood of this forum and FF as 'standard' is very narrow minded sometimes. A 50mm lens is 50mm, whether it's a super tele on a compact or an ultra wide on a 10x8 - it's still 50mm
Like it or not, 35mm was for a long time the norm for most amateur photographers and the current trend seems to be a move towards FF digital. As for your last point re focal lengths always being focal lengths, that's very true (as I've always said). It's the angle of view that that FL gives on the user's sensor/film that matters.

"I want to get some nice bukkake shots, what lens?"
I wouldn't say it was a complete waste of time, its a reasonable standard for a beginner to get to grips with surely.
badabum!
Once you move away from the physical, optical and mechanical equipment that we use to create images then all of the things that are down as "rules" or "must" or "never"........
We work in a creative medium where these things should be seen, at best, as guides or things to consider.......
Example - "Rule of thirds" - yes it is a very compelling compositional principle that can be widely applied to the visual arts - but using the word "Rule" implies "must never be broken" - sometimes there are more appropriate alternatives.......
(And to prevent arguments - yes I use the thirds principle as much as anyone else and totally accept its merit - it's the "Rule" bit I don't like)
