need help with my letus35 FE guys.

[africanmarty]

Nothing is wrong with the housing/product itself (i think) but the footage i'm getting from it is soft. refer to this example: http://uk.youtube.com/watch?v=OaUnDXJEBJo ( will put 720p version up tomorrow, as my internet is capped atm and is runny very slow ). i thought my problem was that i hadnt focused on the GG propely, but today i focused on it again and i still got soft images... now i have a school of thought on this and that is that i am STILL not focusing properly on the GG and the footage ( i'm using the LCD atm to focus everything and maybe that just isnt good enough to get a crisp focus ) and that if i got an external HD moniter, i could focus everything perfect ( focus the gg properly/ the footage properly with the lens and all will be good.)

..BUT i have seen some grabs, footage with these adaptors and they look perfect...(did they all have external HD monitors) why is mine soft ??? any suggestions ?


please help me !! any one else using the letus FE ??

[africanmarty]

ok.. now this is really starting to irritate me !! i plugged the hv20 into my tv ( SD tv ) via Composite Video Cables and it looked great on my TV, the playback was sharp and looked like it did in the LCD ! but earlier when i put it on the computer it looked soft WTF ??? please guys need your help.

an SD tv doesn't have near the resolution of a PC monitor, so even soft HD footage on a PC monitor will look pretty darn good on an SD TV screen

720p version up :

Let me know if you guys think its soft or am i being paraniod.

you know, it does look a little soft. if you shoot with the vibrator off you will see which "side" of the gg the fault is at. if you're focusing the hv20 correctly you should clearly see the grain structure, and if you do it's a lens or collimation issue.

i can see the grain structure of the gg when focusing, so what lens or collimation issues could it be ??? what do you mean by collimation ?

[mattias]

the most obvious lens issue would be a bad lens, either by design or by age and wear. collimation is setting the distance between the lens and the film plane/ground glass. if it's wrong the markings will be off and you will shift the infinity and near limit, but you should still be able to focus by eye at some distances.

i dont think its the lens becuase i used it with a static adapter and got really sharp results, see here :

thats the same lens on a diy static adaptor. and you can see its REALLY sharp.

how do i check this ? what marking will be off ? sorry for all the Q's. thanks for your replies.

[africanmarty]

BUMP. do you guys think the distance between the lens and GG is off.

[mattias]

the distance markings on the lens. i come from the film world so all this talk about hd monitors to set focus is completely beyond me. "don't these people have tape measures"? :-) focus on something by eye and measure, does it match? if it doesn't you might have to adjust things. i haven't used the fe but in general you set the lens to infinity, open it up wide, loosen the lens mount and move it until distant objects become sharp, double check so you haven't lost near focusing, repeat, then lock the mount down.

starting to make sence. though i have never done this before, can i stuff up the adaptor by doing this ??
