Your very welcome Damon you're the model of sharing hard gained knowledge for the good of the community with everything you continue to do with your battery mod thread. In that spirit I also re-posted this on the original X5 lens thread last week for everyone's use. I have recently been testing nonnative lenses, both film and sensor, that may be useful due to the telephoto effects only experienced through adapting. Definitely seems their are some significant gains that may be experienced though the unforgiving weight limitations force very careful application and use. I'm very encouraged by the results from a few set-ups so far but in no way through testing.
Damon, As i haven't yet pulled the trigger on an X5R can you tell me if the "R" requires anything different weight wise with the lenses or is the extra camera and SSD weight limited to the portion attached to the vibration plate thereby negating it's effect on lens balance?
Your experiences with the 15mm are exactly as my first X5 in November. I've had three and although there were absolutely minor differences in how they reacted to the lenses they were all primarily the same in what they wanted so to speak. I feel the differences seen are as a result of manufacturing differences in the zero cog brush less motors which act as both the sensor of movement and the means to correct said motion.
Yes it would definitely seem so. Given what I could see in the photos of it they designed it so that the additional mass was prior to the gimble.
I honestly don't see what they reported to you from a physical standpoint but totally understand what they have experienced. The largest difference in the gimble assembly and what is responsible for the increase in mass is the SSD drive which through its placement has no affect on lens balance. it has been added prior to the first motor and movable part so although it must be supported by the gimble plate it does not require stabilization by the gimble motors. 57g is a very small increase considering what was added so I would be surprised if the camera was heavier. if it has changed in weight it is lighter due to the following attributes. I see two differences at the camera. A shorter rear body which has been offset to the rear and a larger motor to handle vertical pan. By these photos I believe the lens attachment face of the camera has been moved rearward about 10mm, the rear camera housing is about 5mm closer to the horizontal stabilization motor, and the body itself is about 5mm shorter. All of this moves weight rearward in relation to the point of rotation on the pan motor including all lens weights. Although there is no guarantee but with the shift in weight and the increase in motor size it may be able to handle stabilizing heavier lenses. Now as easily as that could be true it could also be that the increased motor size doesn't carry an increase in performance and the changes to the camera body may include a lightening of the lower body which would then result in a net gain of no change in balanced weight even with a different pivot point. However if they have had to add additional weight to the lens then the body has retained a similar weight while the pivot point has obviously changed making the camera more rear heavy which should enable heavier lenses. By how many grams is unknown but even if its a change of 30g it would add a few more lenses. A change in lens balance is surprising considering DJI hasn't provided different balance rings for the few lenses they endorse. Given the extended gestation of the X5R one would expect it to be fully vetted.
I can only report it as i see it and as I have one in hand the 12mm Olympus lens does not balance the same as it did on the X5, in fact on the X5 I had a 5g tyre weight on the rear of the camera and then the balancing ring plus a UV filter ring with the glass removed on the front and this gave me a level balance in whatever position I moved it around in. Also taking those two rings off and putting on the B+W ND0.8 it was also balanced nicely due to the heavier weight of the filter. Now with the X5R and the two rings on the front with no tyre weight on the rear of the camera it tips backwards like a brick. As you stated maybe it has better motors to stabilise the lens, that I don't know but in a switched off position it does not balance the same as the X5 using the same lens and balance rings.
All of this would be due to the difference in pivot point for sure bigger motor or not. That said DJI may have installed a motor which would tolerate more lens imbalance due to the aforementioned changes.
Great! If you can get it at an absolute balanced state I'll plug your findings in and make a new list for the X5R. Although my original testing worked from the 15mm I had gone from scratch on the 12 and the 45 in order to back up my original findings on the 15 so working from the 12 is no problem. If your willing to be guinee pig I'll shoot you the added weight range created by the correction you send me to see if the R is amiable.
