I own several very fun lenses, which are fairly modern with one exception. All but one of these lenses basically have anti reflective coating and baffling for digital sensors and the only film era lens is the outstanding Nikon Nikkor 50mm f/1.2 AI-S. Tamron 28-75mm f/2.8 Effective: 20-53mm f/2.0 https://www.dropbox.com/s/gdeoshe55kr944n/DSC_2733T.jpg Tamron 90mm f/2.8 Effective: 64mm f/2.0 https://www.dropbox.com/s/nam22yppgeoi5cy/DSC_2730T.jpg Sigma 10-20mm f/4.0-5.6 Effective: 7-14mm f/2.8-4.0 https://www.dropbox.com/s/bzewi81cp2turx2/DSC_2725T.jpg Nikon 50mm f/1.2 AI-S Effective: 35.5mm f/0.9 https://www.dropbox.com/s/n4i5z7fp0lmi2l9/DSC_2727T.jpg Nikon 50mm f/1.8 D Effective: 35.5mm f/1.2 https://www.dropbox.com/s/8x05fzesaob0x5x/DSC_2735T.jpg With FM2n Nikon 70-300VR f/4.5-5.6 G Effective: 50-213mm f/3.2-4.0 https://www.dropbox.com/s/pa9g9ye5mba7z7a/DSC_2731T.jpg With the Panasonic 14-42X https://www.dropbox.com/s/746q6mtn344pwoi/DSC_2740T.jpg With the Sigma 18-35 f/1.8A Effective: 13-25mm f/1.2 https://www.dropbox.com/s/rjv1k9urbuwukyj/DSC_2761T.jpg with grip https://www.dropbox.com/s/0xnb2j4nvx9gkiy/DSC_2753T.jpg At no point did it feel like any of these lenses would tear the mount off my camera, nor did they feel "excessively bulky." I do not own the HLD-7 yet for any of these. The 70-300VR was the most massive of the collection. IBIS can handle the 70-300VR at 300mm but not as well as in lens VR, definitely a lens combo that warrants a tripod. The FoV is the same as if I were to mount these lenses on the D200 or any APS-C body. You may actually have slightly more FoV than an APS-C body, 50mm f/1.2: (1.5 x 50mm) = 75mm APS-C (0.71 x 50mm) x 2 = 71mm m43 w/ Speedbooster I'll be posting full resolution images for pixel peeping if anyone wants to. I however don't have test charts.
