Lenses / Re: Why are Cine Lenses so expensive?

which leads me to the next (obvious) question

Is there any advantage for Still Photographers to use cine lenses?

The fact you can afford to buy cine lenses and do buy them to take Still Photography will satisfy an underlying mental need to compensate for other inadequacies you may have. Much the same as buying large white lenses will for some.

Not wiling to spend the $ on something which is at best, marginally better.  I'll take the $ and spend it on travel.  I don't own any Zeiss glass, so Cine glass is definitely out of the question.

Just curious ..

Those light field cameras are just another means of postponing photographic decisions to the office desk. In former times you had to get it all right at the moment of the shot, now we can, thanks to raw imaging correct the exposure later, thanks to cameras like the 1DC choose the right moment later (when recording video, Canon did promote this with the term "micro expressions" google for "micro expressions canon"), now Lytro offers postponing the focusing …

Call me old fashioned, I don't like all this. Off course I also make mistakes and I am happy when I am able to correct them to some extend later on but usually I prefer to choose the right moment, the right framing, the right focus point, the right exposure and the right field of depth at the moment I take the shot.

That's not what the purpose of the camera is for. It is not so you can correct your mistakes, it is so you can make the process interactive. You determine the depth and the focus range in camera. There is just as much to think about when using the Lytro as a DSLR, if not more. This is built more for the monitor than it is for prints. Not saying whether it is good or not, but I find the concept very interesting.

I think too that the technical concept is very interesting. But you need a special viewer to have the interactive aspect for the shots. And then again how many subjects can you imagine (aside from the hand picked examples at the lytro website) where an adjustable focus really makes sense? To me this lytro stuff is still mostly a nice toy, nothing that I would really miss in day to day photography.

What about to increase DOF to your images?  Can allow focus stacking from a single image.

Humm, I'm going to say, my Sekonic light meter.

Just recently sold mine (surprised but Adorama bought it)

Now it is the 300F2.8.  I use the longer glass - this is for my wife to use if she wants a mini-great white :)

Could they be planning on putting their name on someone's else's hardware, a touch of unique firmware, and presto - Nikon MF camera with minimal investment and minimal risk.

Third Party Manufacturers / Re: A7r Arrived - Meeting New Buddies
« on: August 03, 2014, 02:41:50 PM »
i have both a 5dmk3 and a sony a7r.. here are my thoughts on it..

if you bought the sony a7r and a metabones adapter expecting the same performance as a native lens you will be disappointed.. especially dealing with autofocus.. also.. if you expect to take amazing shots with the camera an hour or two into having it.. you're probably going to be disappointed too.. its a tool.. and it definitely has its pros and cons.. but give it a a few days.. and dont try to use it like a canon camera.. its NOT a canon camera.. take some time to learn how it works.. and the menu system. i bought it right when it came out and i'm still getting used to it.

my thoughts on the Sony a7r:
-its def a first gen product.. but a VERY VERY good 1st gen camera. with the sony 55mm f1.8 and 35mm f2.0 auto focus is fast, and photos are incredibly sharp.. is it as fast to focus as my 5dmk3? nope.. but fast enough for street portraits and day to day shooting, yes very much so. i even bring it into concerts.. works well.

-with the metabones adapter it takes 2-3 secs to focus with a canon lens. (most of my experiance is with the canon 16-35mm f2.8 L ) it hunts ALOT.. and you might have to hit the focus button/shutter button a few times for it to focus correctly.. but when it does lock on.. its good and sharp... but it does take a little finess and some patience. the metabones adapter and canon lenses wouldnt be suitable for much more than landscapes and very patient models if you plan to rely on the autofocus.

- focus peaking works very very well. honestly i have pretty much given up on the autofocus with the metabones adapter.. but metabones + focus peaking works very very well.. it takes some practice but once you get it... it works really well. i've been using it with the 85mm and the 135mm f2.0 and had very good results.

- i did a lot of testing right when i got it comparing it to the 5dmk3.. everyone has different tastes.. i'm a slow shooter.. i dont shoot any sports.. but the sony images were (and are) much sharper than the 5dmk3.. i think it has a lot to do with the lack of anti-alising filter.. but it is noticeable.

- battery life is TERRIBLE.. not just bad.. but TERRIBLE.. you get about 300 shots per battery.. so an all day trip takes 3 or 4 batteries for me.. luckily they are pretty cheap.. and charge in about 3 hours.

- luckily you can reprogram pretty much all the dials and buttons on the camera.. i wasnt happy with the default setup at all.

- i too thought i had bricked my camera with the firmware update, luckily the forums had much better instructions than what came from sony and eventually got it to work.

- lens selection is really limited.. canon lenses work with the adapter but its NOT the same as native sony lenses.. the 55mm f1.8 lens is amazing.. the 24-70m f4 is very nice.. but not as sharp as the 55mm prime.

- bracketing/HDR is definately rough around the edges with this camera.. it has some settings but they arent as nice as they should be. you cant set the bracketing and use the timer.. hopefully this will be fixed in a firmware update.

as for the 5d mk3.. i still have it and i dont plan on selling it any time soon. i have a much better lens selection, and it definately does focus faster.

i seem to pick up the sony more.. and take it out more.. its fun to shoot.. its a little more work.. it takes more time.. you have to think abotu your shots a little more.. and be patient.. you also cant just hold down the button and get 1 good shot out of 20 all day long. but at least for me.. when i do get a good shot out of it.. it really does blow me away. 36mp, no AA filter.. gives you LOTS of pixels to play with in photoshop.

Thanks.  I am renting a A7R this weekend and glad I did not buy it.  It is very rough around the edges, I am having no luck with AF and the meta bones IV adapter with 180 macro.

Hoping that Canon does something this Sept to dramatically increase DR so I don't have to buy a A7R.  I could live with it but would rather not.

The single most interesting thing is going to be the sensor in the new camera.  I want to know if Canon is going to compete with Sony or keep putting lipstick on  their current sensor technology.  This will help me decide where my  future camera dollars are going to be spent.

I hear you brother.  No new sensor and I buy a Sony A7R

Lenses / Why are Cine Lenses so expensive?
« on: July 30, 2014, 12:28:51 AM »
Besides that they sell for the price, what does a Cine lens offer than a regular L lens does not?

Flip side - could a Cine lens be used as a still lens?  How sharp would it be?

I've been hoping for a 180 II, but was hoping for f/2.8, 9 bladed diaphragm, and the like, not DO.  Let's hope this is just a defensive patent.

Happy with F4, 9 bladed diaphragm and Tilt functionality to increase DOF a bit

« on: July 28, 2014, 11:58:42 PM »
I used the 70-300 DO once, never again. I'd love to know how many 400 DO's they sell and if the people that buy them are legally blind.

I had both.  Decided that the 70-300L was better fit than the DO so I sold the 70-300DO.

Had the 400 DO, and while good, it was not that good.  In the end image quality was more important than weight.

In the early 2000's I used to use Ebay...a lot.  I gave up on Ebay around 2007 as the fees for listing/selling were too high and shipping is a pain in the butt.  Since then I have used Craigslist exclusively.  I usually get what I want for my gear and have sold numerous cameras this way including: Leica M8, Canon 1DSII, 7D, G12, 20D and numerous lenses.  In addition to selling, I have bought countless gear on Craigslist too which is a nice way to meet other photographers, not to mention try the gear before you hand over your money.

The thing on Craigslist is to sort out the flakes from the people who are serious...also, for Craigslist to be viable you need to live in a populated area (Vancouver, BC is where I am).  No matter what, do not ship to anyone on CL....cash deals only, in person, usually at a coffee shop.

Perhaps I had back luck on Craig's list but all I was scam offers - "I'll pay extra 50% to ship the lens to my cousin in ..."

No serious offers, so after 2 or 3 items I only list on ebay (10% fee plus 3% paypal fee hurts) or Fred Miranda.

Third Party Manufacturers / Re: Anyone own both Canon and Nikon
« on: July 23, 2014, 11:53:22 AM »
I think my previous reply to the OP was very confusing.
So try to rewrite it here:

IIn many ways the Sony A7R is not as refined as the D810 is , but it is a lot less risky and  also much cheaper to get.

And if you do shoot only landscapes or studio set up work , then there is no difference between the D810 and the A7R.

MLFan3

Thanks for the great reply.  I primarily shoot wildlife with a bit of landscapes (would like to do more) and some macro.

For wildlife I will stick, without a single thought of changing, with Canon.

Until the new 16-35 F4 came out, I was very disappointed with Canon WA zoom.  The 16-35 F4 is a real winner.  If Canon came up with a 5D M4 (or ...) that had significant improvement in DR I would be a happy camper.  36 MP would be nice but also will increase workflow (larger files, more disk space, longer processing times, ...)

The Sony A7R looks like a great alternative and need to try it soon. 

Thanks again for the thoughts

This is late (I do not get to sit down at a computer as often) but if you are simply after resolution and hate shadows in your images, I would suggest as some others have done - which is something like the A7R. Purely as a 'digital back' for whatever lenses you wish to use.

As for lenses, I would strongly suggest a couple of Canon's TS lenses before the Nikon's, simply because many of Nikon's lenses of recent years rely a good deal on in-camera corrections, which has allowed Nikon to slack on physical IQ in the lenses. This means that when not used on a Nikon body the lenses do not perform as well. Canon on the other hand, which only recently included/support lens correction in-camera on the very latest bodies, have had to maintain a little higher physical IQ in the lenses.

Sure, most pp software provides lens correction, but not on off-brand combinations.. so you will not get the proper corrections on something like the 14-24mm when used on the Sony body as you would on a Nikon body, and the same goes for the 17mm or 24mm TS on the Sony body, but the Canon's would need less correction to begin with.

Rental of your proposed setup will provide the best information regardless..

To give you an idea on what benefit in-camera corrections can make, DxO has the opportunity to test lenses on an independent body - a real measure of how a lens is designed, built, and performs - by testing on something like the A7R (as it has the same resolution that DxO says makes all the difference in the world) but stated that most people purchasing something like a Nikon lens would be using it on a Nikon body, and therefore any compensated benefits to be had in that combination are relevant to the lenses performance scores.
(Even though in-camera corrections mask the lenses physical design and performance)

Interesting comments about Nikon lens and in camera corrections.  I had not heard that but I know little of Nikon.  That is one of the reasons I started this thread.

I go back and forth on the A7R.  Great camera but wonder if I could use a camera without an optical viewfinder.

Now only Canon would introduce a 5D M4 with dual pixels to dramatically increase DR :)
