10.1 - Are the lenses all the same length?
No, but the distance between the gears is the same. The lenses have a very compact lightweight design to fit to the new small cameras and accessories.
10.2 - Are the lenses checked for fungus and thoroughly cleaned with fungi-stopping baths before rehousing?
We offer lens services on different levels as additional services. An anti fungi treatment is common.
Pls. see Technical Information Polishing – Grinding – Re-Coating – De-coloration
Pls. See our Technical Information about how we judge lenses and suggest lens service.
10.3 - Can I change feet to metric scales?
10.4 - Can you cover the sensors of all digital cameras?
We cover N35/S35 film format, Alexa and Epic in 4K. However the lenses have a ‘natural’ fade towards the corners.
10.5 - Can you rehouse also other models?
By now we can guarantee to rehouse the lenses stated on the flysheet. Other lenses need to be sent in for evaluation.
10.6 - Do you plan on any colour for the engravings and markings?
No, all engravings are white.
10.7 - Does the barrel shift while focusing?
The focus mechanism is a new design. It is an internal focus which means there is no barrel shift. The mechanism is a modern cam drive design. The glass block is not rotating.
10.8 - Does the focus and iris position change?
Yes, focus gear is on the front side.
10.9 - Does the serial numbers stay the same?
10.10 - Focus mechanism: will the lens retain its helicoidal system or will they be cam driven?
10.11 - How about the coating and fungi treatment?
1) coating, fungus, cementing will be checked at receipt and recommendation given
2) uncoating on request possible
10.12 - How long is the warranty?
12 month on mechanical parts by P+S Technik
10.13 - How many witness marks will the lens have?
We do detailed graded witness marks in feet or meter.
10.14 - How much will the rehousing for the Schneider lenses cost?
The price is planed be the similar as for the Panchro rehousing. The fixed price will be available at IBC 2014.
10.15 - Is the focus shift completely eliminated and will not represent itself after a while?
10.16 - Is the focusing mechanism based on a cam drive?
10.17 - What is the lens mount?
10.18 - What will be the front diameter?
The front diameter will be the same on every lens. We plan an 80 mm or 87 mm front diameter. A filter thread is not planed.
10.19 - What's the final size/weight of the lens and what materials are used? How the rehousing technically is accomplished?
The lens groups with the original glass fittings are kept. We rehouse them into CNC machined parts made of aluminium and brass.
10.20 - Which weight has the lens after conversion?
18mm: approx. 550 g
25mm: approx. 500 g
32mm: approx. 550 g
40mm: approx. 500 g
50mm: approx. 630 g
75mm: approx. 750 g
100mm: approx.1200 g
10.21 - Which will be the technical specifications?
Mechanical same as our Cooke Panchro rehousing, but we will reduce weight of the lenses a little more.
10.22 - Will the lenses have a close focus range after the rehousing?
Yes, every lens will come with a close focus range.
100mm: < 0,80m
10.23 - Will the lenses in one set be colour matched?
A colour matching is not possible, a yellow tone of some lenses can be eliminated.
See Technical Information on de-colorization
10.24 - Will there be a threading for screw-in filters?
10.25 - Would you offer a custom case with high density foam for the set to store everything nice and tidy?
We have a very nice foam for 6 lenses which comes as a gift with the return delivery. We can offer an aluminium case for 6 lenses or a high-quality trolley case for 6-8 lenses.
