    Multi Row Panoramas. Biggest issue is D.O.F.

    If buying a tech cam with a separate digital back is not an option, then you can buy a cheap view camera of any kind and get your camera mounted to a sliding adapter on the rear standard, with the lens on the front one and use flat stitching anytime you want. I am not sure how deep the sensor in...

    Multi Row Panoramas. Biggest issue is D.O.F.

    you will struggle with tilts if you use paralax stitching. When you turn your camera around, the lens position chages and the tilted areas between the edges wiill not fit the previous frame - take a look at individual photos you are trying to stitch - there will be a visible difference between...

    Long live technical cameras and digital view cameras!

    I am in love with my Sinar P3. It gives me the freedom of movements I want, is precise enough, relatively small and just fun to work with. When paired with the sliding/shifting attachment of my own construction, I can stitch from 50mpx to well over 1 gigapixel all at the same plane of focus...

    Architecture photography - a proposition for the GFX 100RF

    I think that taking normal shot and cropping in post is much better than trying to figure out what is going on on a 3 inch screen in full sunlight. Also, when you crop badly on your monitor, you can re-crop with no bother, but when you crop badly on a miniature screen, that's it, there is no...

    Intrepid camera shutter project

    that's somehting that did hit me too - the project seems to be outdated with the massive design fault. Large format photographers will not be really interested in electronic based systems, while the same can be reached by simply taking the lid off the lens for a second or two, not to mention...

    Sinar P3 DF - Adapting Small/Medium Format Cameras and lenses

    Just one more thing - if you can, try to buy a P3-DF (DF stands for Digital Focus) instead of the normal P3 variant - the updated focusing resolution can make a difference with focusing. You can easily tell the versions aside by looking at the focusing knob of the Sinar P3 - standard versions...

    Multishot and flash sync - GFX 100 vs X2d with adapted lenses

    I dont know about Fuji, but Sinar multishot backs trigger flashes every time a multishot capture is taken, so in a 4 shot mode you get 4 flashes per picture, in a 16 shot mode that's 16 shots. If you shoot in a dark studio, with a shutter set to a 'B' mode (B stands for Bulb), it keeps the...

    Linos inspec.X L 60mm f/4

    Nice write up! Linos lenses seem to be quite good and can be bought for little money from Asia. Some time ago I bought their InspecX L 105mm which is basically an industrial variant of the 105mm Macro but adjusted for a set magnification only (with no float element) - the lens is quite good...

    Multishot and flash sync - GFX 100 vs X2d with adapted lenses

    I may be wrong as I have never shot GFX, but you should be able to open the shutter in a Bulb mode (B), keep on shooting in a pitch black studio and the flash should sync with every shot. When it is dark, you dont need any apertures, as you can get the same result regulating the flash power...

    Sinar P3 DF - Adapting Small/Medium Format Cameras and lenses

    about problems with P2 getting the correct spacing for optical axis - it can be resolved by using a wide rear frame (quite rear but still showing online from time to time) - this was made for digital backs sepcifaclly and solves the issue on P2 cameras with the tilting point being off compared...

    Sinar P3 DF - Adapting Small/Medium Format Cameras and lenses

    THe strenght of P3 comes from its complete integration with CMV lenses (magnetic-electronic) and that works amazingly well with all Sinarbacks for vibration-free multishots. In P2 you can still use CMV lenses but you need to draw additional cables. Also, P3 is a bit smaller which can be a...

    60mm alternatives to the SK 60XL

    Sinar DB mount for digital lenses is the same specs as Copal 0 in most cases (20mm), at least for cells of '0' size. The myth of problems with mounting it in copal comes from early Sinaron lenses that were very often a combo of copal 0 front and copal 1 rear or the other way round, with internal...

    60mm alternatives to the SK 60XL

    You may look for a Sinar branded 60HR (Sinaron Digital 60HR) as these typically are cheaper than the Rodenstock ones,even though the Sinar's quality checks are tighter. There is also a Sinar's DB mount version that can be had really cheap (for about half price of the Coupal mounted ones) and if...

    Any insights on SK 72mm L versus Rodenstock HR Digaron-W 70mm?

    I think there is still a side by side comparison with sample pictures here on getdpi somewhere. I had both lenses and decided to keep a 72L just becasue it behaves better at wide range of scales - it's image quality remains great regardless if you are shooting at 1:3 or 1:300. It is also smaller...

    Stitching by Shifting versus Twisting

    For me the biggest issue with stitching by camera rotation is that you cannot apply all the camera movements freely (I am using a large format camera with digital). When shifting the back at the rear plane i have freedom to use all tilts, shifts and swings that I want or need. Also, there are no...

    X2D Firmware 4.0 Multi shot 4x added

    with Sinar multishot I was surprised how well it was implemented in their last prudced back,the 'Exact' model - it works perfectly fine in at least 90% shots, regardless of circumstances, while with 54h it was a hit and miss at around 50% and could be ruined by the slightest vibration, for...

    X2D Firmware 4.0 Multi shot 4x added

    Artifacts in multishot backs are sometimes due to the internal shifting mechanism not working 100% corrector, or due to the slight change of lighting, so you can shoot a perfectly stationery object and still get it from time to time.

    IR sensitivity of old digital backs

    I do not think that the IR blocking properties of the IR filters changed with the new backs - I think that the currently used Schott IR glass is the same as with the old models and I think that the most commonly used glass is Schott BG39. Obviously, the sensor may have a different base...

    A Beginner’s Guide to Technical Cameras — Architectural Photography Almanac

    I had a Horseman LX camera before switching to more lightweight Sinar cameras, and it could swing around freely -it was a very useful feature for transport - you could lay it completely flat when swung by 90 degrees, without taking off the rail.

    What are your $500 - $1,000 ‘Bang for the Buck’ lenses?

    @John Leathwick - I think that the Sironar Digital 135mm and the Sironar S are in fact the same lens, or maybe very slightly modified for the field flatness. The Sironar Digital 135mm flavour is quite often available for under $1000 and around $500-600 USD if not in a copal shutter (for example...
