Pablo, Despite what the other two have said, the reverse is actually the case and it used to be normally expected that you would use the same lens for enlarging as was use to expose the negative. Granted, because of modern technology and advancements on both sides of the exposure process, you may not get today as good of results as with separate lenses. I recently bought for less than $150 a very good Nikkor 150 enlarger lens (newer version that sells for $750-$800 US) on eBay. The 50 mm regularly goes for less than $50. A 75 mm for a similar price.
