Sigma150-600mm F5-6.3 DG OS HSM SPORT Lens For Nikon

After using this combo for some time now often in borderline/critical light situations ( Birds and Nature, autumn low light, low cloud, grey in grey, rainy etc) I am impressed by all elements involved. The Nikon D7500 really is a powerful and affordable low light cam and delivers an outstanding overall performance in combination with the Sigma package ( and also the Nikkor 80-200mm 2.8 and the TC 1.4II!). The Sigma lens has no issues with the D7500, focus without the TC-1401 is very fast and reliable ( Result of full speed 7FS with adjustments to Nikon D7500 overall to max. performance for high speed is really surprising: 5-6 Pics are always perfectly focussed and balanced – for me a superb result compared to my previous ‘’quotas’’). With the TC 1401 it still all works perfectly with the Nikon D7500, focus works on all levels ( yes, also around f9 and higher - and at very high ISO’s) and you do get a ‘’reach’’ like that of an a 1250mm lens!! – just a little bit slower but still allowing for up to 3 FPS with similarly good results.Why 1250mm? Sigma is max 600mm & TC1401 =840mm f6, plus Nikon D7500 (APS-C= Sensor Size hands you an angle of view of 1.5x that of an FX camera resulting in the picture seeming to be larger/closer)= comparable to view through an 1275mm f9 (at full resolution of 20.5 mp and not cropped to a lower resolution coming from a 24mp body without a TC)Overall Sharpness of the Lens itself is excellent. Sharpness with the TC is a tiny little bit softer, but not as much as I had expected. Of course ,this all depends on the available light. In comparison to the D7200 (has 24mp but less responsiveness to low light) a picture under comparable circumstances without enlarging or cropping has no visible difference in resolution, ‘’blowing up ‘’ the picture to A3 still does not show a visible loss of resolution with the Nikon D7500 compared to the D7200.I also did a good few tests with a METZ AF-1 52 Flash over the distance of up to 35-40m ( 70-80 yards). Yes, even for birds (and a fox which probably had the shock of his life!) ! – they hardly ever seem to be bothered by a flash. The Nikon D7500 and the Sigma Lens combo work brilliantly for this ( even though this distance seems to be impossible for a Flash) – but for a single pic only. No series ( recharging time of flash) = Works, excellent results and of course enhances the lighting and sharpness of the picture a good bit – even over such large distances.All in all this is probably one of the best, just about affordable ‘’reach out’’ combo’s for Amateurs / ‘’Enthusiasts’’around . Highly recommended.

In the short period of time I have had this lense it has impressed me as quite simply the best long focus lense I have ever owned. Once I learned how to use it properly that is. I am recovering from cancer treatment and the lense is, for me, very heavy so a tripod is essential. I also use a wireless shutter release. Be prepared to adjust ISO settings to keep to an aperture of around f11 for depth of field. I photograph wildlife as hobby and ensuring a sharp duck in the middle of a pond while set to f5 is beyond me at the moment! To sum up a fantastic lense, if in doubt, treat yourself.

Had to return the lens as the autofocus didn't work,tried on 3 different bodies to no avail.had refund and bought the 60-600mm sport lens.

This is one of the best value for money lens on the market. It is well built and a little heavy which you expect from a lens of this quality and price. Super auto focus and zoom lock. Thank you sigma !

Very heavy but very good so far. I can't wait to get out and about for more wildlife photography
