an item over $250 usually requires a signature. this is when you would have the deliverer sign possible damage.

the sensor in question 6.1mp was the culmination of a sony science experiment. i believe it was thier first sensor that awnsered to 35mm digital.

the 16-85 looks like a nice zoom for outside shots. i tend to favor primes for faster (indoor) aperatures.

i removed the locking tabs on all 3 of my m42 adapters and threw the tabs in the trash. never had a problem with lenses coming loose. sometimes i need to swap lenses from m42 to PK in a hurry and have no time to fiddle with getting that ring off the body.

last lens i bought was an old zeiss folder camera with a novar 100mm f3.5 triplet. i converted it to m42 mount and took some interesting shots. i stopped there knowing that pandora's box was wide open.

i have a couple of these cheap adapters and one genuine pentax one. both work the same aside from the aperature ring is not centered on the cheap ones. i removed the locking clips on all of them.

Ive also used non resistant gear in damp conditions. I think it would be handy for sports shooters where the game isnt cancelled by rain. If its raining out i go inside.

I can give you an entire story. My first dSLR was the ist DS and 50mm M series f1.4 my first decent lens. My best shots with it came in Av mode with one hand on the focus ring and the other on the shutter. This offered the least distractions for me to immerse myself in the shot. I really liked the depth of field work but had a hard time with how shallow f1.4 is wide open.
Frustrated by the manual mode requiring the green button I wanted a way to shoot Av around f2.8. I tried the hole method but ended up filling it back in with JB weld:D because I didn't like the less confident snap onto the body. I really thought hard about modifying the body to not engage the stop down lever... I settled on modifying the lens instead as it only cost $50 on eBay.
I tried the Takumar 50 but disliked the yellowing and couldn't find a reasonably priced 8 element version that wasn't worn out. My viewpoint was further reinforced by the fact that every Takumar lens is missing this stop down lever anyway. I don't shoot film and I know people who have/do will disagree with my approach, but is has helped me capture better shots and it works well for me in practice.
Majority of my work beyond f4 I am shooting at infinity anyway. This opened up an entire new realm of disassembling lenses and adjusting the infinity stop as most are off as well. The avatar pic is from a cheapo zoom that had cemented separation. I have since learned and fixed a prime with this issue using mineral oil instead of cement. :lol: Anyway, this forum is great for information and I have learned quite a bit in the past years. Cheers!

the lens is already crippled by todays standards. why live with crippled metering as well?

filling the viewfinder with light isnt a problem until after f5.6. this is the kit lens fastest speed at 55mm... 90% of my shots with any fast 50mm are at f5.6 or below. i see no need for a stop down lever here and having to spam the green button before each exposure is disruptive to workflow.

Had some decent weather and took an outside shot with the Novar/Zeiss at f/11. It's uncoated 3 element design. Attachment 290796 |

its interesting; many people prefer A series for aperture control or m42 for lack of lever. yet i always get pushback when i suggest modifying an M series to operate in the same manner as an m42. the new china 85mm K lenses don't even have levers.

common misconception about "making it through QC" with volumes as they are, QC is about tools to make good parts vs. checking parts after they're made. everyone got this misconception from the shiny gold inspector stickers manufactures used as a "feel good" measure.

Here's phone shot of setup and a quick f3.5 shot. The metering is a bit inaccurate. Would like to find some vintage film post presets. Attachment 289717 Attachment 289718 |

I used an old m42 extension tube for the mount and some pvc for extension. I managed trim to get infinity but its a mm or two before stop. Still on mobile i'll upload some pics soon. Yes its uncoated and flares easy, I am surprised by the center sharpness wide open. I cant imagine what focusing at f3.5 wouldve been like without a range finder.
