Re: This Just Seems Strange

I was looking for used thorlabs parts recently and noticed the same thing. usually I order directly because in europe used parts are hard to find. it's quite simple to do, but I usually have to fill out a form that I don't use the material for military use etc, which delays things a couple of days, ...

Re: 8x HR NA 0.32 + α7R IV 4 Image Pixel Shift Mode

With PSMS there is a 1 EV reduction is noise, equiv. to giving it one more stop light, compared to non-PSMS images. yeah that's another nice side effect - with the S1R 8 shot PS one gets about 2EV better noise performance and thus also 2 stops more dynamic range. interesting that you can use the A7...

Re: USPS Priority Mail Lens Shipments Gone Missing?

Personally I really really dislike the film process.......too much time and work, and then you still need to scan to everything :shock: I wouldn't want to shoot analog for everyday work, but I very much enjoy it for personal projects, specially portraits. and yeah, it takes a lot of time and energy...

Re: USPS Priority Mail Lens Shipments Gone Missing?

Oh yes, this is the golden age of old camera stuff. Nowadays a medium format system that would have costed tens of thousands of dollars when new can be bought for hundreds of dollars. As time goes on, the best lenses will become increasingly rare and sought-after, so now is the time to buy! actuall...

Re: USPS Priority Mail Lens Shipments Gone Missing?

3 cameras in one month! Awesome. =D> you should have seen me in my best days 8) I still use mostly analog gear for my personal photography, and although prices are raising again, a Contax RX can be had for 150-200USD from japan. I already have an RX, lovely camera, but I wanted a second so I can lo...

Re: Newport Damped Optical Posts

in my personal version, I added another ball sledge (without) nut and a second Arca clamp, so the base is much much wider and there is almost no chance of play. that looks super sturdy. which rail are you using? I've been looking for one with longer travel and two sledges and yours looks really nice.

Re: Reversing makro-iris Componons

I used to get a lot of stuff from RAF and still would for specialty things, but getting a 3D printer has simplified a lot of things for me. that's interesting, so you can print lens adapters including threads with a 3D printer? and if so, how would you describe the accuracy and solidity compared to...

Re: Interchangeability of stepper motors?

hi and welcome, it depends a bit how much you know about electronics in general, if you have a solid basic understanding it's quite easy to replace one with another, if it's all completely new then it might be best to stick with the exact parts that are recommended so you have less problems trouble ...

Re: Minolta DiMAGE Scan Elite 5400 vs. Componon 4/28 Tested at 3,1x

lovely test and results as always, thanks for posting!

quick question:
is there a typo in "Mejiro 5.6/90 OT0075"?
I know there's a Mejiro 5.6/90 OTH075 lens, never seen a OT0 series.
just asking so in case somebody searches for the lens it shows up in the result.

Re: EOS 90D vs EOS M6 mkII vs others, suggestions please

I find that is you have one really weak link in your setup, then the others don't matter so much. got a really poor lens? then the camera doesn't matter a lot got serious vibration problems? same got poor lighting? dito got a really poor camera? then optimising the rest wont help much either. so the...

Re: MAG.X 8X / 0.32 LD PLAN APOCHROMATIC OBJECTIVE

wow, going to be exiting. there must be a way to get back tax when you ship things back, after all when lenses get sent for repairs nobody pays tax on the retail price. probably a pain though. In germany, I had to go to the customs office every second shipment that looks like the item is more than 1...
