I had a Tamron 18-250, it was too exciting to not try it out but after all I sold. The reasons? - nearly always stuck on iso400 - lack of contrast - heavy chromatic aberrations - poor color reproduction - the f6,3 at the end killed me - couldn't use after 200mm because of heavy quality (sharpness) loss Of course this superzoom had it's own good sides: - I took down the grip and I had light, p&s-like, but SLR camera - endless possibilities of composition - very good sharpness. A little bit more post-processing in Adobe Camera RAW gives very good quality images since chromatic aberrations, contrast and color can be adjusted but sharpness cannot be recovered.

The first $110 I received... With the check I received two stickers with DT logo, one of them were proudly sticked on the window of my car, the second is still waiting it's best place. The first $110 was completing the amount needed to buy a new gear to start making stock photos. I can say, it was one of my best investments... posted in first $100 used

Anton9, I have Canon equipment but before posting I read about your gear... I have a similar lens, Canon EF 100mm f/2.8 USM, I use it often. Numbers are telling everything. Your lens is a true macro lens that means that at the closest focusing distance (31 cm from the sensor, 15 cm from the front) the lens is projecting the 1:1 image onto the camera sensor. Your sensor has 23.6x15.8 mm, so at 31 cm focus dist. a fly with the length of 12mm will cover half of the image. You cannot go closer or you cannot magnify better. Consider the depth of field also, f2,8 is good for portraits or far objects but around the closest focusing dist. you will need much closed apertures (above f8) and of course more light. Make some experiments with non-moving objects and with camera on tripod. In low light consider using longer exposures. For moving objects (insects) you need really powerful light sources and very closed aperture. posted in Please help with macro question!!!
