Had to laugh at Lord Puss's tirade on poor JoeM--will he live to rise again? colorful as it was The Cat is right on the facts re the Camera's.
Ok I have used the D100 since July last-,and simply the Nikon DTTL system in the camera supports ONLY the SB series 80/50/28 DX flash units in this mode. The capture of 'fast motion' as you mention is something I would not expect the unit to not do adquately in normal use--you're not after bullets shattering glasses are you?--bear in mind it is a function of flash duration that allows movement to be frozen- lesser power output will give faster such duration i.e full power say is 1/250 sec,quarter power would be 1/1000sec therefore cutting down so-called edge blur of a moving object.
Lenses--Hmm? hate to say this but buy the best ones you can afford--I 'm not a fan of Sigma basically most work with the D100 can be carried out with say a 60mm MicroNikkor/ 17-35mm f2.8 AF-s Nikon 28-70 f2.8 AFs Nikkor 80-200mm f2.8 AFs-IED ( ogle at this JC full out a 300 f2.8 on the D100!!
I have the 24-120mm and while it is an Ok optic--it is just not good enough bottle for the D100.
Of course you are coming in for a treat maybe(?) Nikon have released some new DX lenses specially for the Digital SLRs how about the12-20 mm AF-G WA--yummy! and of course the new 70-200mmf2.8 AFS IED VR Image Stabilized version--I've ordered one of those!
Your SB28 can only be used in non TTL Auto and Manual Modes with the D100-fine flash though and with a meter and some simple tests you should not need the DX version
I have not had in my tests nor read any occasion where the DX series flash units are "not fast enough" I do add though that this DTTL (Nikon only !) is a bit of a nuisance particuarly for Macro Underwater whereI have a DX100 housing and must use my Nikonos Strobes on manual only.
Good luck on the D100 hunt--be prudent where you buy-Aus prices are too bloody high!!--check www.dirtcheapcameras .com.au--seem to offer the best local Oz deals.
Yes I'd hoped this forum would get better acceptance-as a snapper for 45years would enjoy a good stouch or two!
Good Shooting,
