If the FD lenses are much better and even cheaper then I no advantage going Pentax

I'm interested more in the 28mm and zoom. Depends if the 28mm at f2.8 is decently sharp.

I've been offered the following Pentax vintage lenses: 28mm f2.8, 50mm f1.7, 35-105 f3.5... anyone ever used these?

the store intelligently raised all the prices of the parts by $200.

You can freely adjust the framing of the sensor crop. Which I really like, would be useful for anamorphic shooting my SLR magic and would really help for event coverage.

So you don't actually get a s35 focal length?

How do m43 lenses cover the s35 sensor?

Something it missing: inbody stabilization, I doubt lenses' IS works right?

Hi,
do you have other lenses with no focus breathing? Seems like almost all the Nikon lenses have it.

Looking for Tokina 28-70mm atx pro 2.8 from Europe. Glass clean and in good condition. Functional AF is not important.

if it cant be downscaled, how come the canon 5d mark iii can do raw full frame at 1080 with a 21mp sensor?

could be because the processor has been developed to downscale in hardware?

I have always dreamed of the GH camera with a super 35mm sensor

 Thanks, why is the Olympus so expensive?

What about Vivitar 24mm f2?

Going to be pretty hard to find for under $500. Nikon 20mm f1.8 is what immediately comes to mind.

I might as well get the samyang the 21mm f1.4 for less.

Looking at the information found about nx300 hack (the one which disables recording time limit), it seems that one way of doing some hacking would be with a firmware update.

Another way of doing it might be through wifi or connecting the camera to pc with a cable. If it would be possible to enter the camera as a developer/debug mode, maybe some code could be changed right in the camera.

As I understand, that nx1.zip file contains the updated firmware 1.4 which is running on the camera. Now when we have access to it, we can find the parameters, that describe the things we need to change, let's try the bitrate first. I just used search and was able to find many mentions of "bitrate" in the zip along with numbers like "min = 6000000" and "max = 8000000". Don't know what these numbers are for, but that is a start. So we need to find the right numbers and pack them in a new firmware update, like the nx300 hacker did.

Here is a description of that process: https://sites.google.com/site/nxcryptophotography/diy-firmware

And then someone needs to be brave enough to test it :D

 

i guess it's 80mbit

I have two questions now:

- do you have a list of the best lenses for money with no focus breathing and parfocal?
- what is the best lenses I could get with an aperture of f2 or lower that is in the 10-24 range? I was thinking a samyang, I'm asking because I need to avoid ISO above 1600 for the NX1 and I noticed that f2.8 from the Tokina 11-16 is not enough sometimes

Obviously vintage lenses are more than welcome!

I was just looking for a constant aperture zoom. I looked on eBay and saw the 35-105mm and then found this. For 30 bucks I thought what the hell. I had a small set of FD lenses. I sold all of them... Some of which I paid 3 or 4 times more, but won't sell this. The only issue I have with the lens is that the filter ring is recessed, so it is hard to mount and nd filter. But even at 5.6 you get good bokeh. In fact, I don't think any of the shallow focus shots in that video were shot wide open. 

So ND filters are impossibile to use?

Great lens. I bought this on a whim for 30 bucks. 

Here it is on an eos-m...

Almost zero breathing and amazing bokeh for an f4 lens. 

How did you find this?? I just love no focus breathing lenses now!

Ok i finally got it... The tokina 28-70mm f2.8 I was looking at is the pro I (2.6-2.8) also known as the best one It looks like that one because it's the same, the difference is in Japan was never marketed as 2.6!

Speedbooster on the nx1?

Anyway what I would like is not a super image quality but just that constant aperture on the focal range with virtually no focus breathing. Sharpness should be just acceptable.

Thanks guys  version 1 is the one reviewed right? Shouldn't avoid this one since it's not from the "legendary" design?

I see, now I'm even more confused. Where did the get the "same optics" info?

It's weird Amazon Italy deleted the item from the site (I guess Samsung decides if the item is discontinued) and now the stock is coming and item is back on the search results 

So let me get this straight: this 2.6-2.8  

and this ATX pro 2.8 

which are identical are two completely different systems?

The ATX PRO is not as sharp, cinematic looking, parfocal and with virtually no focus breathing as the old 2.6-2.8?
I read on here the latest ATX (non pro) http://www.kenrockwell.com/tokina/28-70mm-f28.htm has the same optics as the 2.6-2.8 so assumed even the ATX pro which is in between had the same since it's has also the same body.

If I'm completely wrong then I might just get the Tamron 28-70 f2 for less that has all the issue like heavy focus breathing, plastic build quality etc...

I read that it has same optics as the pro version (it's identical from the outside, it "just" has 2.6). I saw this comparison and to me they're the same and not worth the extra price 

I was asking for the non pro because I could get it for less than the pro.

Does anybody know if the non "pro" version of the Tokina AF 28-70mm f2.8 (with M/A focus switch on the body and where the filter rotates while focusing) also also almost zero focus breathing?
