## Questions & Answers

**Q: Does it come with instructions for attaching it?**
A: No, but i can help a little bit.
This objective is known as a finite objective so you'll have to position it 160mm from the camera sensor.
The other type of objective is a infinite objective which requires a 200mm lens to focus known as a tube lens.
You'll need an RMS adapter, mine is a RMS to M42 for example lots on ebay.
Then you'll need an M42 to whatever your camera mount is.
You'll need some kind of extension tubes to around 160mm between the objective and the cameras sensor. Theres probably a little line on the camera body somewhere to show that
Theres lots more info about this kind of thing here: http://extreme-macro.co.uk/

**Q: Does the objective lens come with a container for it?**
A: Yes a normal objective plastic threaded sleeve

**Q: Can I lower the magnification to 2 times rather than 4 or would I need to buy a different lens for that?**
A: Yes you can. You need to shorten the overall distance from lens to sensor but yes you can. A set of bellows really helps with this.

**Q: Will this fit an old b&l dynazoom. i want to lessen the magnification from the 10x to 4x?**
A: Look at your 10x lens. To fit three things should match: the optical design must match - if you see an infinity symbol on your 10x lens -- the lens do NOT match.
Next the the focal length must match, if you see 170/ on you 10x lens - your microscope is RMS, it can work - but requires an adapter - not worth it . 
If ups see 160/ it is OK, and also the third thing - the thread - most likely will match as well.
