Testing 35mm options

**Ed Hurst** · 02-28-2016, 11:34 PM - **1 Like**

Hello everybody,

Firstly, apologies for the tardiness on my part. My son is fine (thanks to everyone to asked after him - really appreciate it). I have now hit another challenge - not enough space on my Dropbox account to host that number of 645Z raws. Does anyone have somewhere I can upload the files so that everyone can access them?

Many thanks,

Ed

Hello Ed

Not sure if anyone has contacted you yet but how much room do you need?
I can free up 1gig in my DropBox and make a share folder for you to put them into if that is enough.
Send me a private message if so.

Cheers

Can you post large jpgs on flickr for now? Personally I wouldn't need to go as far as to download the raws.

Hello there,

So the amount of data equates to 33 x 645Z raw files (that is bracketed shots from three lenses at f4.5, f8 and f16 plus the same for f3.5 for the two lenses that open that wide).

I think it is over 2 gig as a result.

And I really want to do this with RAWs only because a) it gives people maximum info. to play with and b) it minimises processing done beforehand (which is a variable that could interfere with the conclusions).

If anyone has the capacity for that, I'd be more than happy to upload.

All the best,

Ed

Yeah, just actual-size JPEGs would be fine to evaluate overall quality.

They might do but that involves processing. Why not simply download the raw files and process them yourself when ready? I think since people have gone out of their way to help us out we should be grateful for what we have

Quick update - that file transfer site is not working for me; I can't even register - keep getting an error message that states "could not open socket".

Hmmm...

Will look at getting the DropBox premium account with a larger size limit.

I may be able to help out with this, Ed. I've sent you a PM.

**Ed Hurst** · 03-24-2016, 03:12 AM

Hi Mike - I can see no PM there - would you mind trying again please?

Thanks,

Ed

I resent the message Ed.

all this excitement waiting for the images was just too much for me - I went ahead and ordered the new DFA 35. Anybody need a super sharp A35? I had better not hang onto both.
Can't wait to see your comparisons!

Mike, I can't wait to see your comparisons! Hint, Hint.

I think you will be fine Mike, the DFA35 tested well at Diglloyd and smoked the 28-45 zoom for even-ness across the frame, better contrast at apertures 3.5 to f9 and sharper out to the edges. He classed it as the best lens for the Pentax 645 system, along with the DFA 90mm.
