FS5: What glass Sony or Rokinon

Sure but a zoom has a ton of glass in it.. thats cuts down the amount of light getting through.. a Prime has less of course .. thats why you can have a $300 1.4 Samyang .. but only a T4 S10,000 Canon cine zoom..

You said "if its F11 on a zoom its going to be F22 on a prime" which is just garbage!
 
Not a good example though.. thats not a cine zoom.. its a cheap stills zoom..with a very limited range, to be par focal a cine zoom has alot more glass in it..and to have even close to a decent range.. thats why they are heavy,big and expensive.. not like the above

It wasn't a cine prime either.
 
I am mainly an electronics type guy now shooting video, so sensors, processing etc are my thing, but not glass.

Anyhow I am looking a buying primes now, should I buy the Sony 35mm F1.8 and 50mm F1.8 primes or should I be looking at budget primes, Rokinon / Samyang len kits.

thanks

A grown would struggle to believe there would be two full stops of difference between the T stop and the indicated f stop.
 
I saw JPNola posted a BTS doc in one of these threads. Having just shot one myself, using primes and zooms, our two films couldn't be more different. Hope to be able to post that job in a month or so.

Seeing a handful of shots in a teaser trailer you can know enough of what the entire piece is like to make conclusions?

Without having seen your piece, I suspect that they are different because of the subject matter and not because of "prime vs zoom". Besides, I also used primes for that EPK. Canon, Rokinon, a Zeiss or two, and a 13-blade 52mm Helios 44 f/2. ( how ya' like them vintage lens apples? )

Was I attempting to make art out of that BTS? At times. But most of the time I was just documenting the process in a "videographer" style. EPK, or "Creepy-K" as one Publicist labels it in jest, rarely allows for "DP" style of shooting. I have no illusion that EPK isn't mostly just "tourist cam". What you are able to shoot and the manner in which you are able to shoot it is largely dictated by factors over which you have no control- the confines of the set, the placement of the production cameras, the generosity of a dolly grip, the needs of the Boom Op, the eyeline of the focus pullers, the mood of the actors, the temperament of the 1st AD, etc. You are not necessary to the making of the film and you are subjugate to those involved in the filmmaking process. You are lucky to be able to get onto the set and get any sort of shot at all, nevertheless some artistic framing via prime lens. Most of the time it is ninja-style shooting. From contorted body position pinned between A Camera and a wall along with the Set Photog and having to make effort to remain as still as a statue because you are damn close to the eyeline of a prima donna legendary lead actor who hates EPK, is already in a bad mood, and won't hesitate to eat you alive in front of the entire room should you distract them.

Now, in a bid to see if I can add to the page count of this thread, I point out that we have all been using the term "prime lens" when we actually mean fixed lens or fixed focal length lens.

Every fixed focal length lens in a lens package is not a prime lens.

I am always suspect of any DP / Cameraman who touts that they also Direct, Produce, and edit. :Drogar-BigGrin(DBG)

Calm down, I wasn't dissing your work. I was saying my BTS is an entirely different set-up. For starters, there's hardly any of the main feature in it. And yes, my piece is different because it has to be due to the subject matter and pay masters. Long story which will be obvious once you see the film.

most of the time I was just documenting the process in a "videographer" style.
I thought this point was also obvious from viewing the teaser and again puts it in a very different place to the BTS I just shot. Again, not a judgement of which is better, just a point that these are choices.

I have lenses that have over a stop difference. Of course two stops is extreme. And by "grown ups" I'm referring to cine crews using cine lenses.
 
Damn fellows, it's the weekend. :beer: Still brushing off a hangover.... Jason - your post # 12 only stirred up the nest.
Let's go back to the original posters question for just a second... if we might, cause I'm curious.
I have not shot much at all using any modern "electronic " Sony lens (have not tried the G series yet) so not sure I would pick that over a Rok or other affordable alternative that offered manual iris and hard stops with focus. Have others here found IQ worth it on some of the Sony's?
 
Haha - I once shot an EPK on a Sean Penn film and was told that I needed to shoot Sean, but that if he saw the video camera anytime when he was on set , anywhere, he'd throw a fit and I would be thrown out. I tried to explain to the producer that if I could see him - then he could see me - no way around it, but she didn't seem to get it. I ended up shooting a long shot of a scene in an airplane cockpit from the airport through the windows with the camera balanced on a garbage can so I wouldn't be near it! Couldn't see a damn thing. I got paid though. Couldn't have done it with a prime !

If you look at the reviews the Sony G primes do pretty well in IQ tests it's just the electronic focus that is the issue for most people. I don't understand the need for the variable speed focus, surely it could be possible for Sony to turn this off and have a more directly coupled feel for video users? Most photographers wouldn't touch the focus ring so why don't Sony make it useful for video?
 
That is totally my issue with them. I've used the "kit" lens (28-135) exactly once. Tried it out for a r & g type shoot in very dusty, dirty environment hoping to keep from having to swap lenses. And have also used the sony 16-50 cheap "kit' lens with my a6300 for gimbal work. Both produce ok images... certainly not great. And maybe I'm old school, but just can't get past that electronic focus - screams "CONSUMER" even on the rather amazing autofocus on the 6300... I'd rather be riding focus myself.
 
You said "if its F11 on a zoom its going to be F22 on a prime" which is just garbage!


How so.. its basic physic,s.. thats why primes are nearly always faster stops than zooms.. as in my example.. you pay $35k for a 2.8 zoom.. and $10,000 will only get you 4.4.. light transmittion a fairly easy concept to grasp.. less in the way.. more gets through.. 2 stops isnt some accurate thing I calculated .. just to make a point.. if you are F11 on a zoom.. without any ND,s.. you would also be at at least the same on a prime .. probably more..

If Sony would give us some manual focus, manual iris "cinema style" lenses that don't scream "CONSUMER" we wouldn't gripe so much about the electronic focus on their hybrid lenses intended primarily for the still photography market.

I know, I know. You were talking about Sony zooms.
