Re: Ancient non-AI Nikkor 50mm ƒ1.4 — Photographed using an equally-ancient 28mm ƒ3.5

Seemed like, of all the things I had easily at hand, this is the subject that would be most in keeping with this month's theme. A late 1960s- or early 1970s-vintage 50mm ƒ1.4 Nikkor.

Although this 50mm, mounted on my D3200, would amount to a 77.5mm equivalent, I wonder if it'd be considered acceptable in this assignment to submit a picture taken with it. If I find other subject matter that seems to call for it, perhaps I'll submit my other two allowed entries, one using this 50mm, and one using the “kit lens” zoomed as close to a “50mm equivalent” as I can reasonably get it.

I think you might have hit on an idea for another challenge: "use a prime"? But for this one, the intent is to stay close to the perspective that a 50mm FX, 35mm DX or 18.5mm CX provides.

How bout if I just set my 18-55 on 35 mm, since I don't have a 35mm prime?
Plese tell me you're not discriminating against people who can't afford one right now.

You're good with the zoom set to 35mm. At least, that's how I read the OR an equal focal length with a zoom comment.

I'm assuming a 28mm prime with a DX at 42mm isn't quite close enough?

Just to reiterate... we're doing a focal length of 18-35mm with any type of lens (if we don't have a prime)?

I don't think that's correct. The 18mm end only applies to CX crop, and the 35mm for DX. the question is, can you travel north or south of those numbers, and if so, how much? 35mm on a DX is really 52mm, so I'd think a 52mm or even 55mm might be ok on FX, and if that's the case, why wouldn't 28mm (44mm equivalent) be in range on DX?

The thing is, if you don't make it a fixed length for each crop, you run the risk of edging beyond the lines. It's easy enough to dial in a zoom by checking the EXIF on the shot, but as always, it can creep. This challenge is already more complicated than it should be. And I'm not helping. LOL

Haha... I'm not up to date on all the terminology... I just learned what a "prime" lens was when I joined here a little over a month ago. lol I have a 18-55mm and a 55-200mm lens for my camera (D7000). So what "fixed" length can I do it at?

Using your 18-55mm zoomed to ~50mm on the D7000 would be safe. The gray area would be if you used the 55-200mm zoomed out all the way to 55mm.

Actually, the above is only right on full frame cameras, which the D7000 is not. FX cameras are looking for ~50mm. DX cameras (like the D7000 or my D5300) need to be 35mm since after crop factor is nearly equivalent to the 50mm (actually 52mm) field of view. So [MENTION=25730]Tom Grove[/MENTION], you would use the 18-55mm zoomed to 35mm, and the 55-200mm is not really an option for this round.

Apologies for my mistake.

Thanks RC... That's what I understood too, but I would rather double check.

That's next months contest. Every month it will go up 5mm, Until only people withe Tamron 150-600 are able to participate.;)

I'm quite sure that some old full-frame 35mm cameras had “normal” lenses as short as 40mm; so a 28mm lens on a DX—equivalent to about 43.5mm—ought to be considered within this range.

But if I stack enough teleconverters, and have an atomic explosion as my light source, can I still use my 35mm prime when we get to the super zooms? :D

Depends on what your EXIF is showing. (Iwill consult my other buddy, Max the Wonder Dog).

That would be my thought as well.

I believe you are shooting DX so an 18-35mm as long as the focal length of the submitted image was 35mm.

To be consistent with the answer for Jake above, I'd have to say no.
