I’m up­grad­ing to a full-frame body, mainly for shoot­ing con­certs and in­door events, but I also love wildlife pho­tog­ra­phy. On my bud­get, should I get a new D750 or a sec­ond­hand D810 or D3S? Si­mon Scot­ting

Ja­son says... the D810 and D3S are more up-mar­ket, ‘pro-grade’ cam­eras but I’d def­i­nitely go with the D750. The 12.1Mp im­age sen­sor of the D3S is quite old and fairly low in res­o­lu­tion. Con­versely, the 36.3Mp sen­sor of the D810 has great re­solv­ing power, but im­age noise is more

of a prob­lem when shoot­ing con­certs or in­door events, where you’ll of­ten need to use a high ISO set­ting. Com­pared with both of these cam­eras, the late gen­er­a­tion 24.3Mp sen­sor of the D750 cou­pled with the same Ex­peed 4 pro­ces­sor that’s fea­tured in the D810 de­liv­ers far su­pe­rior high-iso per­for­mance. In this re­spect, the D750 is one of the best DSLRS ever made. The megapixel count and 6.5fps max­i­mum drive rate also make it very adept at wildlife pho­tog­ra­phy.

I’m con­fused about which lens to buy with a new D750 body. Is the 24-120mm VR or 28-300mm VR bet­ter? Also, are D-type lenses com­pat­i­ble and can I still use my DX lenses? Vin­cent O’neill

Ja­son says… Per­son­ally, I’d avoid the Nikon AF-S 28-300mm VR lens. The mighty zoom range is nice to have but per­for­mance is lack­lus­tre in terms of sharp­ness and dis­tor­tions. Nat­u­rally, the AF-S 24120mm VR doesn’t give you as much tele­photo reach, but de­liv­ers sig­nif­i­cantly more wide-an­gle cov­er­age, which can be a big bonus. Im­age qual­ity is sig­nif­i­cantly bet­ter and the f/4 aper­ture rat­ing re­mains con­stant through­out the zoom range. Clinch­ing the deal, the 24-120mm costs around £1080/$1100 to buy on its own but, if you pur­chase the D750 as a ‘kit’ com­plete with this lens, its price ef­fec­tively drops to about £450/$500. Bar­gain! Also, yes, D-type lenses are com­pat­i­ble with the D750 and you can use your ex­ist­ing DX lenses in ‘Crop’ mode, although the max­i­mum avail­able im­age size will shrink to 8.75Mp.

Do you know of any kind of con­verter that will en­able me to use my old Sigma Sony A mount lenses on a Nikon cam­era body? Frank Bauer

Ja­son says... I’m afraid the short an­swer to this is ‘no’. I’ve never seen one and I also checked with Sigma for you, just in case. They said that due to the flange dis­tance, the large dif­fer­ence in phys­i­cal size of the rear of the lens, and the elec­tron­ics, it’s not vi­able to make an ef­fec­tive con­verter. Sigma does of­fer a mount con­ver­sion ser­vice for some of its more re­cent ‘Global Vi­sion’ lenses, but this isn’t avail­able for the older mod­els. Sim­i­larly, Sigma also mar­kets a mount con­verter for us­ing some of its own Sony A and Canon-mount lenses on Sony E-mount bod­ies. Nat­u­rally though, that won’t re­ally help you with those Nikon bod­ies.

Do you know of a com­pany that can re­move the anti-alias fil­ter from my D5100? Ken Flatt

Ja­son says... The ben­e­fit of re­mov­ing the anti-alias (AA) fil­ter is that it in­creases the cam­era’s po­ten­tial to cap­ture very fine de­tail. The trade-off is that it’s more sus­cep­ti­ble to moire pat­tern­ing and false colour. Some com­pa­nies do of­fer a ser­vice to re­move the AA fil­ter from cer­tain Nikon cam­eras and re­place it with a non-aa fil­ter, but I’ve never seen the D5100 on their lists specif­i­cally. It’s also an ex­pen­sive pro­ce­dure that typ­i­cally costs more than the D5100 is worth. A much bet­ter and more cost­ef­fec­tive so­lu­tion would be to sell your D5100 and up­grade to a cam­era that doesn’t have an AA fil­ter. For a DSLR that’s a sim­i­lar size and spec­i­fi­ca­tion, you could go for a D5300, D5500 or D5600.

A con­sum­mate all-rounder, the D750 beats both the D810 and D3S for im­age qual­ity at high ISO set­tings

The price of the 24-120mm VR is heav­ily dis­counted if bought as part of a D750 kit

It’s pos­si­ble to have the mount and elec­tron­ics of most Global Vi­sion lenses changed, but it can work out cheaper to sell the lens and buy the al­ter­na­tive Nikon-fit edi­tion

Later edi­tions of Nikon’s D5xxx se­ries cam­eras from the D5300 on­wards omit the anti-alias fil­ter
