This question occurred to me when I replied to Dogman's thread about lens characteristics and I decided to start a new thread about it. So here it is, to people who have high-end glass and have done comparisons:
Do you notice a lot of differences in sharpness and resolution when using ISO 400 films or do they eliminate the differences between good and excellent lenses?
The quality of almost all pictures found on the internet certainly does obscure most differences between lenses anyway, so I'm asking for opinions based on your own comparisons printing in the darkroom, projecting or with excellent scanners.
Less interested in other characteristics such as speed, field flatness, bokeh or color here, as these are not obscured by film with lower resolution or bigger grain.
I'm thinking about 35mm lenses, medium format is certainly different in this regard.
 
High end glass is always worth it, no matter what film you use. Buying really good lenses is a far better investment for you than either the film or the camera.

That and a good tripod. 🙂

I believe there is a difference, yes, or so my eyes tell me.

I am referring to the difference between, say, a 50 summilux asph (excellent) and a canon 50 f/1.4 ltm (good). Not the difference between, say, a 35 summilux and a 35 VC.
 
Define the end of high for you first. Is it some f1 Noxtlust? Then yea, you could shut it at f1 @400.
This fear of 400 comes from MF scanners. I'm @3200 135 format dr printer. I see if lens is good on prints. It is not about grain, but tones where.
 
Yep, I agree with the previous posters. Better (high end) optics may not always slap you in the face but there is often a subtle, hard to describe quality about how they render images.

I've been shooting digitally for the past 10+ years so how I shoot may not exactly translate to your question concerning 400 speed film. But I have all my cameras to default to ISO 400. Since I shot Tri-X and HP5 for decades, 400 is the norm to me. Better lenses that perform beautifully still perform beautifully at higher ISOs. Of course bad lighting conditions are still bad lighting conditions and you can't expect a great lens to compensate for crappy lighting (even though it sometimes can at least get you a usable picture).
 
I think there's some confusion here:

I think the implication is that ISO 400 film may obscure the sharpness/acutance possible by some lenses (ostensbily high-end and expensive). That's conflating potential sharpness with "high end". I would expect a "high end" lens to be more than just sharp....and oddly those other qualities were sort of discounted in the OP. A high-end lens will hopefully be well corrected for a variety of abberations and errors as well as optimizing acutance. So for me, the argument falls apart.

I have a cheap lens that is amazing tack sharp in the center, and very much not sharp as you move away from the center. I also have a high-end lens that is quite sharp across the entire field, but probably not quite as sharp as that central spot of the cheap lens.

But for the "masking effect" of film. Yea, I occasionally read about certain lenses that were sharper than "the emulsions available at the time of their production". Still, simple sharpness helps when using grainy film. Getting all your wavelengths to focus with similar sharpness is really helpful.
 
Does “high end glass” mean it’s gotta come with a high price?

I wonder.

I own a 50mm f1.4 Canon lens I use with my digital stuff that I’ve had made pretty large photographs. It cost me less than $400.00 new and It’s always on one of my Canon cameras.

Here is info on it from B&H:

For film:
Doesn’t make much of a difference what ASA film I use. Quite a few components are necessary for my photography with camera, lens and film just a few parts I consider.
 
Thank you for the responses so far, if I'm not directly replying to your post, please interpolate from the replies to those who made similar points😉.

How's film not better investment than all equipment?! I thought that was forum consensus, at least as long as we're not having GAS ourselves😎
Kidding, you mean the differences between lenses matter more than those between films? That might stir some controversy if we're talking good vs. excellent glass, not bad vs. good!

Does “high end glass” mean it’s gotta come with a high price?

Not necessarily, I left that up for your own definition. Whether you read it to mean "differences between lenses I'd consider good and lenses I'd consider excellent" or "differences between <20 $ vs. >20 $" or "differences between <2000 $ vs. >2000 $", all interesting.

Cool so you'd say better stick with film that allows fast shutter speeds because visually they're not that different?

I was indeed assuming high end lenses to be sharper on average. Of course there are exceptions and that should be most evident at wide apertures and at the edges of the frame, sure. Why you read my post to mean sharpness/resolution was the only criterion for high end I don't know.
I was postulating that sharpness and resolution would be the only qualities that might be obscured by grain. So doesn't it make sense to talk about these qualities exclusively in this context? That does in no way imply that other qualities are not important in a lens.
Please give my question a charitable reading. Perhaps I wasn't expressing myself very well, English is not my first language.
No question that sharpness helps even using a grainy film. It would be interesting to know if anyone has noticed a limit beyond which more sharpness, that a given lens is capable of delivering, does not help.
Edit: I see how the thread title lead to your reading of my question. Yes, without doubt there are qualities other than resolution and sharpness that make high end lenses worthwhile, so I didn't chose a good thread title.

IMHO glass is always a GREAT place to invest. Keep in mind when you print you should have great glass on the enlarger too, same for projectors. Every piece in the chain that you use to deliver your final image is important. But if you start with mush, best you will ever get is mush. Not that mush is bad mind you.......

Rather like looking at an image on an old Mac II Apple monitor vs an iPad Pro.

Well, speed is purely a lens characteristic. But subtleties in any of the rest of those attributes are progressively obscured as the MTF goes down and the grain structure becomes more crude.

If you really want to groove on the utmost subtleties of bokeh, shoot large format and make contact prints. (Of course if you don't terribly care, that's OK too - to each his own.)
 
I'd like to see some side-by-side comparisons to make a judgement, but my intuition is that the grain of ISO 400 black and white film would obscure most of the benefits of a better lens. As far as resolution is concerned, there's no question that grain limits resolution. Any lens performance test that didn't disclose the type of film shot, or which compared the lenses on different films would be suspect.

Various types of chromatic aberration, field flatness, distortion, vignetting, and edge resolution loss will all be apparent even on grainy film. But if we're comparing good lenses with great lenses, would these flaws be present? And if there are only subtle differences what's the amount you'd be willing to pay for something marginally better?
 
The crappy imaging chain degrades with every crappy step in it, so yes, you will do better with 400-speed film and a good lens than 400-speed and a Holga.

By the way, modern 400-speed film is quite good these days.

These are my thoughts exactly, that's why I was wondering if anyone has made comparisons. And yes, some of these flaws will also be present in many good lenses I think, there are many aspects to choosing a lens and we have different priorities there, that's the other thread, I wanted to focus on the aspect of of resolution/sharpness and their relationship with grain here.

I thought I had made very clear that this thread was supposed to be about good vs. excellent rather than crap vs. good lenses :bang:.

You're right of course that there are some very, very good ISO 400 films, the answers will certainly be different for TMAX than for Kentmere.
 
I don´t see any reason why "high-end-glass" should not be worth for any ISO.
There is lens characteristic and film characteristic. No dependency.

None? ISO 400 films don't resolve much more than 100 lp, some far less. If you said that in practice, film doesn't significantly limit the output, ok, but I won't take "none" for an answer. 😎
 
My Leica 35mm Summarit makes Fuji 400H look "digital" with very crisp details and high contrast edges. Compared to other decent lenses like my 40mm Sonnar, pictures are not as detailed and seem to result in more grain and less vivid colors.
 
When was the last time the success or failure of a photograph turned on the resolution of the lens? I am not talking about depth of field or focus, but the actual resolution of the lens.

I find that using good glass on any camera weather film or digital will always be very good.
With film though unless you are using good glass to scan or print will also make a difference if you are after crisp images.
Like all the previous post nothing is better than good glass.
