Originally posted by Weber I'm actually quite easily tempted by cheap, interesting glass... but the desire to keep my whole kit portable, plus the fact that I have to move often, has been my most powerful anti-LBA talisman so far!
Ah, you're a perfect candidate for a small bellows, a focusing helicoid, and a pile of tiny cheap enlarger lenses! Let's see, a good starting set would be :
* EL-Nikkor 50/2.8 (100g)
* Vivitar-LU 75/3.5 (70g)
* Novoflex Noflexar 105/3.5 (120g)
* Ilex Anastigmat 140/4.5 (260g)
Except for the beautiful EL-Nikkor, all these can be used for general photography too. My M42 Bellowscope weighs 230g; the 17-35mm focusing helicoid weighs 110g; a set of M42 macro tubes are maybe 40g. All these, with less weight than any Vivitar Series 1 70-210! Or you can skip the bellows and the 140, and the kit weighs about the same as a DA10-17! Just don't forget the lens hoods. Cheers!
