In other words, the flash's speed is the limiting factor rather than the shutter. It seems like basically every stop of reduction in the flash output offers the equivalent of about 1/3 of a stop of max sync speed? Ish? These things are not necessarily always going to be consistent, though, and generally there's at least another 1/3 of a stop of leeway where there is some loss of light due to sync speed but it's not enough to badly throw off the shot if the exposure is otherwise in the right ballpark. Turning on HSS provides marginal improvements at high outputs (another 1/3 of a stop at 1/1 or 1/2, basically), but more in the vicinity of a full stop around 1/4-1/8. Going to even lower outputs continues to improve the sync speed, but with this camera, those lower outputs are of minimal utility. | Kolari KV-FL1 Flash Power | Max Safe Sync Speed | HSS Sync Speed | | ------------------------- | ------------------- | -------------------------------- | | 1/1 | 1/125 | 1/200 with a slight exp penalty | | 1/2 | 1/200 | 1/250 | | 1/4 | 1/250 | 1/400 with a slight exp penalty | | 1/8 | 1/320 | 1/800 with a slight exp penalty | | 1/16 | 1/400 | 1/1250 with a slight exp penalty | | 1/32 | 1/500 | 1/1600 | Taking all of the above together, shooting at "1m", ISO 400, f/5.6, , 1/200, and 1/2 power should be workable for street shooting distances in low light. (Actually that setting would be a little too much indoors and probably a bit underexposed outdoors.) f/8 and 1/1 power will be safer from a DOF standpoint though. ### SB-26 The SB-26 on max power is very similar to the Kolari flash (with the same filter) but its sync speed performance is much better. Best news of all though is that the non-TTL auto mode works quite well, as does the LCD distance scale. There is about a 3-stop offset in the ISO, i.e., for the GRIII in ISO400, use ISO50 on the flash. | SB-26 Flash Power | Max Safe Sync Speed | Notes | | ----------------- | ------------------- | --------------------------------------------------------------------------------------- | | 1/1 | 1/320 | It is still fully practical to shoot around 1/500-1/1000 but exposure will dip slightly | | 1/2 | 1/2500 | The labeled 1/2 power is actually 1/4 of 1/1, but it can sync at any speed | | | | | So, sensible flash settings are probably: - 1/1, 1/320-1/500, f/5.6-5/8, ISO 400 - 1/2, any speed, f/2.8-5.6, ISO 400 - Auto, ISO 400 on camera, ISO 50 on flash. Flash scale will be reasonably accurate, set aperture accordingly ## Flash vs. LED: | Model | Aperture | Shutter | ISO | | ---------------------------- | -------- | ------- | --- | | Ghost Light without diffuser | f/1.8 | 1/320 | 100 | | Ghost Light with diffuser | f/1.8 | 1/160 | 100 | | Nightfox XB5 Zoomed Out | f/1.8 | 1/80 | 100 | | Kolari KV-FL1 | f/11 | N/A | 100 | ## Presets Need to Review/optimize these: ### U1 (Sunny 5.6) - Shutter: Auto AF - Fn: Enable AF (select) - Touch to select AF Point - Exposure: M (5.6, 1/100) - ISO 100 ### U2 (1/125) - Shutter: Auto AF - Fn: Enable AF - Touch to Shoot - Exposure: Tv (1/125) - ISO Auto Max 400 ### U3 (Tracking No Touch) - FN: Enable AF - Focus Mode: Tracking - Touch input off - Exposure: P (1/125, 2.8) - ISO Auto Max 800 (??) # Color ## Presets ### U1 (Viewfinder) - Display off. - Primary focus mode: Snap - Exposure: M, f/11, 1/200 - Touchscreen: Off - Snap Distance 1.5m ### U2 (Street) - Primary focus mode: Tracking - Exposure: Tv (60) - ISO: Auto with minimum shutter speed of 1/60 - Fn Button: AE Lock - Touchscreen: Touch to shoot ### U3 (Bike) - Primary focus mode: Snap - Exposure: Av (8) - ISO: Auto with minimum shutter speed of 1/160 - Fn Button: Temporary AF while held - Touchscreen: Touch to shoot # Panoramic Shooting ## DIY viewfinder mask notes 1" x 1.75" outside Inside .5" x 7/8" ## Stock viewfinders - Horseman 617 90mm finder would be pretty close to the Ricoh with GW-4 in pano crop. ## Angles of view [Calculator](https://www.pointsinfocus.com/tools/depth-of-field-and-equivalent-lens-calculator/#{%22c%22:[{%22av%22:%228%22,%22fl%22:45,%22d%22:3048,%22cm%22:%220%22}],%22m%22:0}) Cropped Sensor Areas | Size | Full | 2.7:1 | 2:1 | 16:9 (1.78:1) | | | ---------- | --------- | -------- | -------- | ------------- | --- | | Full Frame | 36x24 | 36x13.33 | 36x12 | 36x20.34 | | | APS-C | 23.5x15.6 | 23.5x8.7 | 23.5x7.8 | 23.5x13.2 | | | Camera/Crop | Lens | Horizontal Angle of View | Vertical Angle of View | Diagonal Angle of View | | | --------------------- | -------- | ------------------------ | ---------------------- | ---------------------- | --------------------------------------- | | ==Widelux F-series== | | | | 140 | | | RP 2.7:1 | 10 | 122 | 67.4 | 125 | | | RP | 16 | 96.7 | 73.7 | 107 | | | RP 16:9 | 16 | 96.7 | 64.6 | 104 | | | RP 2:1 | 16 | 96.7 | 58.7 | 103 | | | Lomo Sprocket Rocket | 30 | 100 | 43.6 | 103 | | | ==RP 2.7:1== | ==16== | 96.7 | 45.2 | 100 | Quite close to the XPan 30 | | Sigma Quattro H 2.7:1 | 12 | 96.1 | 44.8 | 99.7 | Sigma 12-24 SA mount?
