When I was younger, like ten or twelve I can't remember exactly... my friend down the road from my Gramma's had gotten an Estes Model Rocket kit for his birthday. That was soooo coool! We flew it a few times.
I didn't have money. But I had a library card. I took out some books on chemistry and Werner Von braun.
I scrounged up some scraps and household items and built my own rocket.
Going with liquid fuels for a first try was, how shall I put it? Ambitious.
I blew a hole big enough to bury a coffee table in, in Gramma's back yard.
That afternoon, my friends dad came over. He handed me a baseball sized rock (that had landed on his shop roof in his yard).... "This belongs to you I presume?" then he handed me a brand new Estes Rocket kit, Just like the one he gave his own son... "Play with this, it's safer."

Me and my friend, his son later that day got in trouble for damaging a parked car with a toy "Rocket car", sadly the frog piloting the car did not survive.
Live and learn... (if you live) I always say.

looks a little over exposed.

1/45 sec...??? why?
if using only flash no point in using anything other than 1/160 to 1/180 sec...
if balancing flash with ambient... then ok use whatever...

at f 1.4 you may not be able to use multiflash accurately.. stop it down a couple stops....

we'll need some exif info and lighting set up info....

it is really easy to build battery replacements....
you take the right diameter wooden dowels and cut them slightly shorter than aa bateries, then screw in screws to the ends of the dowels and solder wire leads to them. insert instead of batteries and connect the leads to your ac power supply.
I do it all the time, hardly ever blow anything up...


ps glue sticks work if you cannot find dowels...

to be honest, I'd go for the 2.4.
I might just buy myself a second one for shooting 3-d.....

"Find my iphone" is the one my wife uses most. To stalk me.
if you have a mobile phone, do not give the number to your boss or your spouse (which in my case is one and the same) or you might as well be wearing a leash..

flixter and maps.

My 16-45 and 28-70 f4's leave me satisfied and wanting not for any other zoom lens that covers the same range.....
they are my studio zooms, and only get taken off where a prime lens is needed.

for that kind of money... I will build you helicopter drone with camera and you can fly your Pentax camera over to what ever it is you want to photograph.....

I have a pentax 85 mm lens hood that fits my 35 2.4 and does not vinette.
My suggestion is ANY standard or collapsable 35-50mm (49 mm diameter) lenshood will work. Optex and optima brands are usually easy to find.
