anybody want to sell me a lens?

Tired old lenses? When is a lens tired and old, when it goes to bed early? Honestly, a good lens is a good lens if it's 25 years old or 1 year. And yes, many "tired, old" lenses come close to HD "specs" or perhaps you didn't read the above thread on HD vs. SD lenses. My Canon J series lens which I used on my Betacam for 16 years is now on my HPX and produces stunning images. The general consensus is that the average viewer, not a tech with a scope, can't tell the difference. Your point of view is in the very distinct minority.

Or, is it possible that perhaps you might be in the group that so desperately wants the cheaper (cost) SD lenses to work that they will defend their use against any other opinions? Perhaps, you're not but I've certainly formed that opinion from some others posts.

One of the problems in trying to sort out what really works and doesn't work on internet forums like this is that we all use our equipment for a wide variety of end uses, but we don't we don't make that clear in our posts. A wedding shooter or someone who cranks out local car commercials will post their opinion as quickly as a 20 year film veteran, as they all should. Problem is that we don't know who is who, most of the time.

An example would be a post in this thread in which it was said that "we use SD lenses for broadcast everyday." I'm sure that's accurate, but I also believe that their version of broadcast is local TV commercials. Quality in that venue is extremely variable. But, it doesn't matter because the SD lenses get the job done and that's all that matters.

Contrast that against someone shooting for national HD broadcast and you can see the inevitable "space" between opinions.

That's why I think we should all be careful about calling someone inexperienced or untrained because they might not like their opinion.
 
we should also attempt to be less condescending....

whatever. i haven't looked at my old canon sd footage with a fine tooth comb yet but i will say this. i am looking at playback thru my 42" plasma right now and i am completely blown away by this quality. i'm not seeing CA at all. i purposely shot a lot of hard edge, high contrast stuff to see how bad it would be and i am shocked to find nothing. i do have more breathing than i would like to see but still not too bad considering i am racking from 4' to 15' at 70mm. still i will look for a lens that doesn't breathe as much. i tried out one of the lower end hd lenses at the camera shop and it breathed just as bad as this one so i am convinced that unless i am spending 20-30k on a hd lens, i am much better off with sd.

I did not use the words "inexperienced" or "untrained" to respond to the post in question. I merely questioned the poster's comment that one could not find a quality broadcast SD lens worthy of the HPX for under $400 for use in a "serious application". And his comment "you'll see that on Ebay" is patently ridiculous since I've seen just the opposite. Also, the fact that he (?) has something to sell -- namely a $3K lens - casts immediate doubt on his dubious claim. As far as "desperately" wanting to defend my SD lens goes, I think your statement is insulting not only to me, but to every shooter on this board who uses an SD lens, is more than satisfied with the results, and sees no need to pony up big bucks for a minor improvement in picture quality that hardly justifies the exorbitant price. And, just for your info, I've never shot a wedding or a car commercial in my life. I wouldn't need an HPX for that.

Im glad you are using what I posted to be diligent about it. Thats the reason I put it out there, because I do see a lot of CA in SD glass.
 
Ladies, Ladies, C'mon. The truth is most video people are so discerning when it comes to their images. If you want a crystal clear HD image, forget the HPX-500 all together, no matter which lens you put on it. I use and love the 500s, but it is what it is.

Stop bitching and making an argument for SD lenses versus HD lenses. We've been over it time and time again and again. It's up to each individual and what works for them. For myself, the SD lenses work great. For others, they don't. Can't we just leave it at that? Geez, seriously.

Let's just argue about HPX 3000's vs 500's and the costs difference - oh wait, same thing. People DO WANT A GOOD CAMERA FOR LESS MONEY. If that means SD lenses, so be it. I make money with my cameras everyday. They were paid for in the first few weeks of getting them. Why? Cause I didn't break the bank with expensive lenses. And can any "normal" person tell the difference? No. No they can't. They're used to watching SD in a 12Mb stream on their cable channel. DVD looks 1000 times better and the 500 with just about any lens you throw on it looks 1000 times better than that. So, c'mon, let it go already.
 
Kit, last time I checked people were entitled to have an opinion. Some are very adamant about theirs and wont listen to others, whilst some simply wish to inform.

And I rightfully think that everyone should be entitled to their opinion, never said otherwise. But you're fooling yourself if you think that posting the same thing about the same topic that has been discussed a hundred times in these forums is beneficial to anyone. We all know you have a choice. You can choose to purchase a HD lens or you can choose to purchase an SD lens based on what you need. Read through the threads, do a search, ask specific questions that have not been asked, but beating the same topic to a pulp and a constant arguement about it is in no way beneficial. We have long since established that a SD lens will work for some and not for others. There's only so many ways to say it.

So last time I checked, the question of whether or not an SD lens will work has been "informed" to death and long since established. Not looking for a pissing contest, just get what you can afford, what works for you and what your clients need / request.
 
you guys take this outside... lol.

i scored an old nikon 15x8.5 today for $100. it's even sharper than the canon. i will post some grabs later.

and for the big big score of the day.... the place with the lenses had a sachtler video 20 III head with carbon fiber sticks and spreader sitting there. i asked how much and the lady says 2 grand. so i quickly started to examine it to see what was wrong with it. not a thing. besides a few scratches, it's perfect. i quickly whipped out the credit card and giggled the whole way home...

anybody need a cartoni focus head on bogen 3193 sticks? because i don't anymore.

maybe i got lucky. or maybe i'm not staring at a computer and picking apart the images. it makes more sense to me to view it the way my clients will. and there is no ca at all on the tv.

i can't believe that these broadcast quality sd lenses are only capable of producing a 720x480 image. that is nuts.
 
but a certain amount of CA is definitely apparent in most SD lens.
I dont see it cannot be corrected with some tweaking on the tiffen DFX chromatic aberration filter...it really does a great job taking out the blue and greens!
