Technical Support / Re: How many shutter actuations does Reican Focal take?

Hi Folks.
Thanks Badger, was hoping to know that for myself by now.
Oh well I tried focal tonight, got target up, set up camera on tripod square right height etc. Start test and get the message failed to download image, process timed out.
Turns out my laptop which I thought might be slow is past it! :'(
Hope her old laptop (better than mine but still not new) will manage to work. Not sure the long USB cable from upstairs will be that practical! ::)

Cheers Graham.
I ran into miscellaneous problems like that once. Doing a fully manual test worked fine.

There you go. 83 sounds like a lot (and you can get good results with less), but it actually doesn't take all that long. It is faster than doing the Fully Automatic Mode with manual intervention which is the only alternative when using a 1DX or 5D mark iii (I have tried both methods).
For the shutter actuation count of the camera, it is probably insignificant for most of us :)

A few dozen per lens usually. Some users prefer to do the shots manually (not tethered), and then load them into FoCal. Then it is up to you how many you take. Neuro described here in the forum how he does it, and I believe he takes about 80-something shots (more than FoCal would take)

I read that cars have their logos taped, athletes are asked to cover the logos on their smartphones if they are not made by the official sponsor, same for computers etc etc. seems pretty strict.

Lenses / Re: 35mm f2 IS for city photography at night?

Different strokes for different folks I guess, but I found the Sigma 35 Art to be a game changer. Before I bought it I rented both the Sigma & the cheaper Canon at the same time to compare and to my eyes at least it wasn't even close...

Now for my style of shooting, sharpness is everything... The Sigma at 1.4 is every bit as sharp as the Canon at 2.0 http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=824&Camera=453&Sample=0&FLI=0&API=0&LensComp=829&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=0. With both lenses at 2.0, the Sigma left the Canon in the dust http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=824&Camera=453&Sample=0&FLI=0&API=0&LensComp=829&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=2

Don't get me wrong, I like image stabilization as much as the next guy, but for me 35mm is easily wide enough so that IS isn't really necessary. But to each his own...


Maybe in the center, but  in the corners the Canon 35mm f/2 IS looks a bit sharper to me than the sigma, both at f/2 - I wonder if the difference is visible in real life landscape shots
note: there was an extra . at the end of the URL which caused the link to fail

Third Party Manufacturers / Re: D4S Specs confirmed.

Adorama isn't a rumour site. They won't write anything unless they've got something to write.
Unless they create placeholders ahead of time with unconfirmed specs that they get from rumor sites :)

Thanks. Have you tried the Samyang? It's one of the few Samyangs I haven't owned/used. I'd be interested in hearing a first-hand experience! If the Samyang has a worse IQ though, it's not worth it, you get what you pay for, I rather pay more. Who ever heard of a cheap TS lens! I'll read the review you linked now.

Ps. is the 17mm L or not? I though it wasn't an L lens but amazon lists it as an L lens! Which is it?

No, I have not used it. According to reviews it seems to be a less-expensive alternative to the Canon if you don't plan to shoot with apertures wider than f/8, if you don't expect the same image quality, but you need the tilt-shift. At $1000 it is not exactly cheap.

Here are two more articles by Roger:

There is a 24mm Tilt-Shift for Canon EOS mount by Samyang/Rokinon for about half the price, with lesser build and image quality.
Edit: The-Digital-Picture.com has a review here: http://www.the-digital-picture.com/Reviews/Samyang-24mm-f-3.5-Tilt-Shift-Lens-Review.aspx
Schneider makes also Tilt Shift lenses for Canon http://www.bhphotovideo.com/c/search?atclk=Lens+Mount_Canon+EOS&ci=274&N=4288584247+4291231926+4108103567 but they are not cheap. See Roger's take on the 50mm version here http://www.lensrentals.com/rent/canon/lenses/specialty/schneider-50mm-f2.8-super-angulon-for-canon

Pricewatch Deals / Re: Rokinon/Samyang 14mm f/2.8 $275
« on: January 28, 2014, 12:13:36 AM »
Rokinon FE14M-C 14mm F2.8 is the name in the ebay ad, but is it a different version than the one found in internet reviews (Lenstip review, etc), aka Rokinon 14mm f/2.8 IF ED UMC?

No Rokinon developed an entirely new lens with the exact same specs as their best selling 14mm lens, specifically so they could disappoint customers but offer a 20% discount. It's brilliant decision making if you ask me. :P

I'm not sure the sarcasm is warranted.  I believe Samyang/Rokinon did have an earlier version 14mm that was no where near as steller as the current (reviewed) model.  I suspect the poster wishes to avoid making a mistake.   Does anyone know the answer?
There is a Samyang UMC version, and there was an earlier MC version which was slightly different and was produced only at the very beginning (as far as I know - I think wikipedia has something on that). I have seen the Rokinon branded only labeled as MC, never as UMC. I believe they never cared to update the name for the Rokinon branded versions

I trust you realize that a single off-camera flash set up is just a gateway drug.   ;)
Isn't that true for most gear recommendations? :)

Didn't Roger also write something on his website that Imatest values should not compared between different testers/labs? I think you are just doing that. I doubt that DXO and lens rentals have an identical test setup.

so the x is a DPP-only phenomenon (or feature)?

Long exposure noise reduction is not recommended for ISO 1600 or higher, if I remember correctly from my T3i/600D manual. Not sure if that has changed. Maybe the algorithms are overwhelmed?
