Thank you, Pere, for the time and effort you put into your answer. You're a real asset to this forum. Cheers!
Angénieux.
There is nothing wrong with making your preferred lens a special one with the desired treatment, especially if you don't care about the cost of it.
Perhaps SK Grimm could do the disassembly and...
Don't know, Pere, but the less spread the light source has the more your posts are spread... :confused:
I'm on the same wavelength with Pere, in this.
From your posts history it is clear that you're on the very beginning of photography knowledge. Nothing bad with that except that it is not sufficient...
The Fresnel part has grooves that are easily damaged by rougher handling. Best to send it to Maxwell indeed, because you don't know the details enough.
Provided they know how fragile plastic Fresnel lenses are - I would not bet on it. It's not the cutting that is problem, rather the handling of the grooves.
Have the glass cut by a professional, the plastic by a cutter.
Hmm. Then cut it in the way that doesn't ruin it!
Indeed, some people could get sleeping disorder from it. :)
But back to the OP's question. The answer is that the glue was an innovative product and did not have the historical time behind it before...
Obviously, before measuring your shutter speeds, you have (and you should!) to exercise it. Start with slower speeds, activate each of them several times and go up to the highest speeds. Listen...
Well spotted, Pere! (in fact the 5 is still hardly visible). Kudos to your eyes!
An example, or just hot air?
OTOH, if the idea was supported by many members... then... I would not hesitate to nominate... its author! Why?
Heck, frankly, I mean that anybody with that number of posts (and growing!) on this...
Just a sincere sombre premonition (intellectually evaluated). :)
You know the Clint Eastwood's saying about opinions? I like that. And yes, I did understand that your judgement was just an opinion, not based on any technical measurement or other valid comparison....
Please, a time for you to reread this forum's guidelines. If you're not able to restrain yourself from name calling, restrain yourself from commenting. Thank you. To weed the technical BS is good for...
I'm of that humble opinion that I just contributed to the understanding of the technical value of your comparison judgement. Don't take it personally, it's the scientific part of me, you know, the...
You easily saw the difference? Interesting. Could you compare the same scene taken with a different lens, in the same light, on the same camera - to say at least some conditions necessary to make a...
Sorry if I missed something, it doesn't sound like you have shot enough with that specific lens before you decided it had lower contrast than other lenses.
And no, even older designs with single...
I gladly refuse any nomination of my person as I think it could severely damage my CV. :)
Again, don't know if I should be impressed or not. Can you elaborate on how, technically, you compared the contrast of these lenses?
Hmm, interesting.
And you compared it with your other lenses on the same scene, the same light conditions, the same camera etc.? Or does it just mean that this picture had "somewhat lower contrast"...
Also a good one, yes. It makes you want to understand in depth the technique of our photography and that is always good.
Surprised nobody mentioned that yet - Using the view camera by Steve Simmons. Also The view camera by Harvey Shaman and there are a few more, this is just what comes to my mind.
Good grief!
Much better than polishing lenses, IMHO...:)
Let us not divulge the secrets more than we have already done, please!
Filters are made of a specially produced glass to keep both their surface planes strictly parallel. I think after reading this thread filter manufactures will take the LFPF much more seriously, to...
Have you never tried with a lens??
Let's say it in this way - you're right that you can polish an acrylic dome in this way. But a lens is a different thing.
The dome doesn't have the function of a lens. All it needs to be is just...
It may rain today too... :)
Nothing at all - I've read it. Not one word about amateur incorrect lens polishing to cure lens scratches.
And what has that to do with the polishing technique discussed in this thread?
Indeed, that's well possible - similar effect you can get even by filling the scratch by black ink. It is however a different scenario than that of the OP. Still you make a correct point - it is...
Without going into details of why one cannot compare the acrylic domes repair with a taking lens amateur polishing - have you already cured a lens from scratches with your polishing technique? (I...
Unfortunately, in this case one cannot use the same technique on modern lenses, as suggested.
With a Dremel fitted with polishing felt? You mean, it's a cure to replace a scratch with a different than original curvature area much bigger than the scratch? You cannot be serious.
